MIDI Echo - The MIDI Echo module repeats incoming MIDI events using a customisable feedback path. - The Echo Path sublane receives each repeated MIDI event for processing. - Repeats are tracked using MIDI channel numbers. - It supports up to 16 repeats. - The interval between repeats can be set in seconds or using tempo-synced values. - While the module is optimised to avoid stuck notes or infinite repeats during normal use, it can still be pushed creatively. - For example, inserting a MIDI Channel module in Modify mode within the sublane can produce infinite repeats. - In such cases, the Panic action is available in the module actions menu. - The module also includes an indicator for when the echo buffer is full. - MIDI Echo is a Mela Lab module and part of Collection 5. Other Changes - Mod Steps: The Retrig parameter has been renamed to Trigger, adding a new behaviour where, in Step mode, the sequencer advances to the next step on note-on. - MIDI Delay: Redesigned the module UI. - MIDI Delay: Renamed the Mode parameter to Sync and added tempo-synced options 1/64 and 1/128. - MIDI Delay: Fixed an issue where modulating delay time could cause some MIDI events to be delayed by an incorrect amount. - MIDI Delay: Fixed an issue where changing the On parameter state while processing notes could cause stuck notes or orphaned note-offs. - MIDI Channel: Fixed an issue where changing parameters while processing notes could cause stuck notes or orphaned note-offs. - MIDI Channel: The Channel parameter is now controlled with a dial instead of a pop-up list. - MIDI Source: The new Note Number source option maps MIDI channels 1 to 16 to a stepped [0%, 93.75%] Mod signal. - Digital Delay: Added an indicator to show when the built-in clipper is active. - Signal Indicators: Updated Feedback's clip and Note Pulse's pulse indicators to match the style of Digital Delay's clip indicator. - Parameters: In the parameter actions menu, the presets section is now labelled. Parameter presets appear under Presets, while list and toggle parameters use Values. - Factory Presets: Added the "Euclid Sequencer" preset to the Parts group. It uses Euclid to generate rhythm and Mod Steps to provide the notes. - Presets: Fixed a crash caused by a malformed preset, with a Root Stack submodule that's not a Group type.

Mod Steps - The Mod Steps module is a simple yet powerful 16-step sequencer modulator. - Its flexible parameters enable sophisticated, evolving patterns. - Modulate Start and Length to create moving sequences. - Retrig controls whether the sequence follows the host or restarts on note-on. - Cycles sets how long the sequence runs. - Modulating Cycles between 0 and infinity can freeze the pattern at intervals. - Mode adapts the sequencer for different uses, including note and MIDI generation. - Each step can be modulated for dynamic patterns. - The module includes actions to randomise or reset step values. - Mod Steps is a Mela Lab module and part of Collection 5. Note Pulse + Mod Steps - Note Event and Note Pulse pair naturally with Mod Steps. - For example, 3 Mod Steps modules with Note Pulse can build a note sequencer. - One in Pitch ±12 mode controls pitch. - One in MIDI mode controls velocity. - One in Unipolar mode controls note length. - Check out the Note Sequencer preset in the Parts group, which demonstrates this setup. Factory Presets - Added a new factory preset group called Parts. - Starting with 3 presets, this group will grow over time with reusable presets that can be dragged and dropped into your own presets. - Added the "Pulser" MIDI preset, showcased in the latest Note Pulse demo video. - Added the "Drone 1" and "RM Resonators" presets to the Pads group. Other Changes - List Parameters: Dials and sliders now once again update values while being adjusted instead of on release (restored pre-3.3 behaviour). Tapping or clicking the title/value button lets you select a value without intermediate changes. - Modulation: List or index-style parameters now respond evenly to modulation. - MIDI Logger: Copy and clear actions have been moved to the module's actions menu. - Modules: Lane-level preset drops now mirror module moves, adding a wrapper lane only if the root module is not a Group. - CC Modulator: The module graduated from Mela Lab and can be found under the Modulator category. - Mono Modulators: CC Modulator and Mod Steps always operate in Mono mode, generating a Mono Mod signal and leaving the incoming Mono or Poly signal unchanged. - AUv3: Plug-ins now correctly report the Mela version number. - Ableton Live: Fixed an issue where the Mela UI did not appear after the plug-in window was closed and reopened. - Note Event: Fixed a bug in Skip mode where increasing Velocity from 0 could trigger note-on while Gate was already high. - Internal: Global parameter value loading improvements.

Reusing Presets as Modules - Presets can now be reused as modules, making it easy to move structures between presets or build complex setups from existing designs. - This allows presets to act as reusable building blocks within larger signal chains. - Any module can be dragged out of Mela to export it as a standalone preset. - Dragging a preset from Finder or Files into Mela inserts it as a module. - Modules can also be dragged between Mela instances to insert a copy. - In all cases, the full nested structure, parameter values, and modulation routing are preserved. - Presets in the browser include a drag handle. - Drag a preset to Finder or Files to export it, or back into Mela to insert it as a module. - Presets or modules can also be dropped onto the User or custom preset groups to save them there. - When inserting a preset as a module, global parameters such as Ahead and polyphony settings are not imported. - Be mindful of Audio and MIDI bus usage, as imported presets may use the same buses as the current preset, which could lead to unexpected routing behaviour. Note Pulse & Note Event - It's now easier to turn Note Pulse and Note Event modules into step sequencers or note generators by modulating their Velocity parameters. - Note Pulse: When Velocity is set to 0, new pulses are not generated. - Note Event: Added a Vel 0 parameter with Skip and Off modes. - Skip prevents note-on generation at velocity 0, while Off also releases a held note. - The Event parameter has been renamed to Gate as it is more fitting. - Note Event: The On parameter has been added back. It is useful when note generation is triggered by modulation, allowing it to be turned off. Other Changes - Audio Input: Side-chain input is now supported when Mela is loaded as an instrument plug-in.

Unison Module - Optimised for stacking oscillators to create a classic unison effect. - Processes submodules in parallel, similar to Stack in Sum Audio mode, with built-in detune and stereo spread. - Each submodule receives a differently detuned Pitch signal, and the outputs are spread across the stereo field before being summed. - Levels are automatically scaled to maintain consistent gain. - A more natural sound is achieved when oscillators use random start phases on note-on. - Detune: Sets the maximum detune depth in cents. - Stereo: Sets how widely voices are spread in the stereo field. - Unison is part of Collection 5 and listed under the Signal Router category. Other Changes - Nesting: The Group and Ungroup features have been generalised into Nest In and Unnest, extending support to container modules such as Stack, Effect, MIDI Group and Unison. - Mid-Side: The module now supports Poly mode and no longer collapses a Poly signal to Mono. - Slew: Allows Rise and Fall parameters to go as low as 0.01 ms. - Parameters: The Enter Value menu item now appears above the parameter presets. - Presets: Updated the default preset. - Strummer: Fixed edge cases that caused unexpected behaviour. - Note Length: Fixed a bug where the note length was not updated when adjusting the Time parameter. - Modules: Fixed a 7.1 regression that prevented intensity values from being duplicated when a modulator was duplicated.

The 7.1 update introduces Collection 5, kicking off with creative and essential audio tools. It includes Frequency Shifter for metallic and inharmonic textures, a transparent brickwall Limiter, and powerful new modulation tools: Slew, CC Modulator, and Mod Oscilloscope. Collection 5 will continue to expand with every 7.x update and is available as a one-time purchase. Frequency Shifter - Frequency Shifter offsets all frequency components in the Audio signal by a fixed amount, producing metallic or inharmonic textures unlike pitch shifting. - Provides useful tweaks with parameters: Shift, Range, Mode, Stereo, Mix. - Shift: Sets the shift amount within the selected Range. Linear ranges map directly, while Cubic uses a non-linear curve for finer control near 0. - Range: Selects the maximum shift amount. Linear ranges map -100% to 100% directly. Cubic is non-linear and spans ±5 kHz. - Mode: Selects how energy behaves around 0 Hz. Clean is single-sideband. Reflect preserves down-shifted components below 0 Hz. Duplicate adds mirrored components when shifting up. Both combines reflect and duplicate. - Stereo: When enabled, left and right channels shift in opposite directions. Limiter - Limiter is a brickwall limiter that provides transparent peak control using a lookahead gain envelope. - Includes standard controls such as input gain, attack, release, and channel linking, along with a gain reduction meter. - Offers character modes for either faster response or smoother, lower-distortion limiting. Slew - Slew is a modulator that smoothly ramps the Mod signal toward a target value. - The target is set by the Value parameter and can itself be modulated to smooth another Mod signal. - Ramping can be linear, exponential, or a blend of both, controlled by the Curve parameter. - The Rise and Fall parameters determine how quickly the Mod signal responds when the Value parameter changes. - The indicator lets you visualise the current value of the Mod signal. CC Modulator - CC Modulator uses incoming MIDI CC messages to modulate parameters. - Unlike other modulators, each target can be configured to use a different MIDI CC source. - This provides an alternative way to automate parameters from the host. - The host can send MIDI CC automation curves, which are translated into parameter modulation. - CC Modulator is a Mela Lab module. Mod Oscilloscope - Mod Oscilloscope visualises the modulated value of its Offset parameter. - Modulating Offset at 100% intensity displays the modulator's Mod signal directly. - For best results, set Offset to 0% for unipolar Mod signals and to 50% for bipolar signals. - The module can also be used to visualise how another parameter is being modulated. - To do so, apply the same modulation settings to Offset as the target parameter. MIDI Meter - Added the MIDI Meter module for visualising incoming MIDI values. - Displays a 16-circle vertical meter and a numeric value readout. - MIDI Meter is part of Collection 0 and listed under the Visualiser category. Arpeggiator - Added an indicator that visualises the active note position within the chord. - Added Manual mode, where the new Position parameter selects the next chord position across the active Oct Range. - The Position parameter is a great target for automation or modulation, enabling custom arpeggio patterns. Other Changes - Meter: The module now has a more minimalistic appearance with no sidebar, as there is little benefit to keeping it collapsed or showing its name. - Meter: Updated the DSP implementation for a more natural response. - Band Pass: Now supports Poly mode and no longer collapses Poly signal to Mono. - Module Actions Menu: The menu now displays the module name as the title. If the type is not clear from the name, the type name is appended in brackets. - Modulators: Refined the appearance of the modulators' drag target icon. - Module Categories: Replaced the Utility module category with Visualiser.

The 7.0 update brings long-awaited Undo and Redo, making it easy to revert unwanted changes. Perform View has been generalised into remote views, allowing remote controls to be assigned to any Group or Stack module. The design has also been refined across the app to improve consistency and visual cohesion. Undo/Redo Support - Changing a parameter value. - Adding, duplicating, moving, replacing, removing, or renaming a module or lane. - Adding, removing, or replacing a modulation assignment. - Grouping or ungrouping a module. - Adding, removing, or renaming a remote control. Remote Views - The Perform View feature has been generalised and is now referred to as remote view. - Remote view consists of remote controls. - Group and Stack modules, in all their forms, support remote controls. - Any submodule parameter can be exposed and controlled by an ancestor module. - Since lanes are Group modules, they also support remote controls. - Because every preset is powered by a root-level Stack module, Perform View assignments in existing presets automatically migrate to remote controls and appear in the Global remote view. - Remote controls can be created or removed via the actions menu. - All parameter types are supported, including list and toggle parameters. - Remote controls can be renamed with custom names. - Controls are automatically ordered to match their appearance in the preset structure. Lanes - Collapsed lanes now move to the bottom in a horizontal scroll view, where their remote controls remain accessible. - They still participate in lane and module drag-and-drop for rearranging. - Tapping the lane sidebar scrolls all the way to the left, unless it is already scrolled, in which case it collapses as it normally does. - Tapping the Global sidebar lets you collapse or expand all lanes. MIDI Source - The Input parameter has been replaced with Source and Number (or Note). - To configure the module to respond to CC messages, set Source to "Control Change" and specify the CC number using the Number parameter. - The Number parameter lets you limit the module to a specific note when Source is set to "Note-On/Off Gate" or "Flip-Flop on Note-On". - Source now includes a "Note Number" mode, similar to "Key Track". - While "Key Track" is optimised for frequency-based modulation, "Note Number" maps the full MIDI note range [0, 127] precisely to a [0%, 100%] Mod signal. - For example, modulating the Control Change module's Value parameter with MIDI Source set to "Note Number" lets you convert note numbers directly into CC values. Stack Module - Previous updates made the On parameters more performance-oriented, and this update introduces further refinements so the Stack module feels more integrated with other modules. - Toggling off a Stack submodule's On parameter now stops outputting submodule signals completely, rather than outputting the same signal as its input. - In Sum Audio and Ring Mod modes, the Stack module's On parameter acts as a crossfade between its input and output, just like the Audio Processor modules. Other Changes - Toolbar: When there is not enough horizontal space, toolbar buttons appear as menu items when tapping the toolbar's ellipsis button. - Preset Selector: An asterisk now appears next to the selected preset name whenever there are unsaved changes. - Presets: Trying to load another preset when there are unsaved changes now displays a confirmation dialog. - Preset Browser: Folder icons are now displayed in front of preset group titles instead of chevrons. - Preset Browser: The User and custom group folder icons include a user badge to make them easier to distinguish from the factory presets. - macOS: The window title bar and toolbar have been merged. - Menu Bar: Added many useful actions, along with keyboard shortcuts, to the menu bar in the standalone app. - Zoom: The macOS and iOS zoom resolutions now match exactly. - Zoom: The preset browser, toolbar, and about view no longer follow the zoom setting.

Pitch Ramp Module - The Pitch Ramp module linearly ramps the Pitch signal toward the incoming value over a defined interval when a note-on event is received. - It is a useful module for creating simple pitch envelopes quickly. - The ramp interval can be defined in seconds or as a tempo-synced value. - The Range parameter, with a -48 s to +48 s range, defines the pitch offset the ramp starts from on note-on. - Pitch Ramp is a Mela Lab module and part of Collection 4. Factory Presets - Added 3 new presets to the MIDI FX group: "CC Remap", "Drums-to-MIDI", and "Velocity Remap". - Added the "Rich Saw" preset to the Leads group, demonstrating how the Pitch Ramp module can be used to create rich sounds.

Mela FX & Mela MIDI In some DAWs, different plug-in types are listed together, which can make it harder to see which Mela type you are selecting. This update renames the Instrument and Audio Effect types to Mela FX and Mela MIDI correspondingly. Keep in mind that the only difference between the types is the number of audio and MIDI inputs and outputs. Otherwise, their features are identical and any preset created in one type can be opened in another. MIDI Group Module - The MIDI Group module works similarly to the Group module but is optimised for processing note events. - When the module is on, the sublane receives all MIDI events from the parent. - When it is turned off, held notes are retriggered directly to the parent's output, bypassing the sublane. - Turning it on again retriggers the held notes to the sublane's input, and its processed output resumes being sent to the parent. - The sublane receives only the parent's MIDI input, and only its processed MIDI output is forwarded. - All other signal types in the sublane are isolated. - MIDI Group is part of Collection 0 and is listed under the Signal Router category. Note Hold - Added a new Mode parameter with options: Sticky, Retrig and Chord. - In Sticky mode the module behaves as before and turns every second note-on of a given note into a note-off. - Retrig holds a note and retriggers it whenever the same note is received again. - Chord builds a chord until all note-off events are received, and then releases the chord on the next note-on. - Chord mode feels very natural when used with a physical MIDI keyboard, especially when the Hold parameter is modulated using the Sustain Pedal (CC64) message. - To time out notes in Retrig and Chord modes, insert a Note Length module after Note Hold and set the Length parameter to "Fixed". - Updated the module UI to support the new features. - Fixed an issue where the module did not always display the held notes in the correct order. - Sticky Mode: Fixed a stuck note issue that occurred when the Hold parameter was enabled between a note-on and its corresponding note-off event. Other Changes - Euclid: When the On parameter is toggled off during an active pulse, the module no longer retriggers held notes. If no pulse is active, it waits until the next pulse to retrigger them. - Note Stack: Fixed an issue where a note-on/note-off pair could pass through even when the Play parameter was set to 0, if both events arrived at exactly the same time.

VA Oscillator - Merged the "Full-Wave Rectified Sine" and "Half-Wave Rectified Sine" waveforms into a single "Rectified Sine" that supports the Shape parameter, allowing it to smoothly morph between the two shapes. - The "Alternating Sine" waveform now supports the Shape parameter, allowing it to smoothly morph from a pure sinusoid. - Factory Presets: The new "G0 Euclid" and "Demo 6.12" presets in the Synth FX group showcase the new features. MIDI Processors - With this update, the transition to making the On parameter performance-oriented across all modules is now complete. - The On parameter of the following modules is now more performance-oriented: Arpeggiator, Note Echo, Note Range, Scale, Strummer, and Quantiser. - Each MIDI Processor uses the On parameter in a way that best suits the module's function. - For example, the Arpeggiator retriggers the input chord when turned off, while the Quantiser simply stops quantising new notes. - Note Range & Scale: Changing any parameter, including On, updates the output by releasing some held notes and triggering new ones as required. - Chord Module: Fully rewritten internal logic, making the module more robust, especially when its parameters are modulated. - Note Stack: Removed the redundant On parameter. - Note Stack: The module no longer creates a note-on event for a note in the Wait stack if it's also going to be released in the same call as the note-on that freed a slot in the Play stack. - Note Stack: The module no longer generates redundant note-on/off pairs when receiving multiple note-ons simultaneously. - Note Length: Fixed an issue where the note length value didn't always initialise correctly. - Arpeggiator: Fixed an issue in Chord mode where a note-off event could be generated for a new input note-on before it was sequenced. - Transposer & Scale: Fixed a stuck note issue that could occur in certain edge cases. Other Changes - Stuck Notes: Adding, removing, or moving a module now forces all modules to reset, preventing stuck notes even while the preset is receiving note-on events. - Amp Envelope: Fixed an issue in Mono mode where note-on events weren't detected correctly when Legato was enabled and multiple notes were received simultaneously. - Fixed a crash that could occur when a modulator's last target module was removed from the preset. - User Guide: Added the new "Module On Parameter" section to the Core Concepts chapter.

MIDI Processor Modules - The On parameter of MIDI Processors is now more performance-oriented, meaning that even when turned off, they continue to monitor input and update their internal state as needed. - This prevents them from sending unnecessary note-off messages when turned off. - For example, turning off Euclid, Chord, or Transposer releases the held notes and retriggers the input note-on events. - Turning them back on sends the corresponding note-off events for the inputs and retriggers the output. - The new behaviour makes them more robust and user-friendly while helping prevent stuck notes. - Updated modules so far: Euclid, Chord, Control Change, Groove, MIDI Channel, MIDI Delay, Note Chance, Note Length, Note Pulse, Overlap Remover, and Velocity. - Modules to be updated in future versions: Arpeggiator, Note Range, Note Stack, Quantiser, Scale, and Strummer. - Transposer: Adjusting the Semitones parameter now releases held notes and triggers the new transposed notes. - Note Event & Note Hold: Removed the redundant On parameter. - Note Hold: Fixed an issue where the Hold button wouldn't always display the correct state when modulated. - Note Pulse: Fixed the Sync parameter defaulting to 4 bars instead of 1/4. Chord Module - The Note On and Pitch parameters now retrigger note-on and note-off events when their values change. - This allows adjusting the parameters and hearing changes instantly without needing to feed the module a new note-on event. - Modulating these parameters can lead to interesting algorithmic compositions. - It's recommended to place an Overlap Remover module after the Chord module to prevent earlier note-off events from interrupting the latest notes. - Velocity parameters now use percentage units, controlling how much the note velocity moves toward its minimum or maximum value: -100% moves fully toward 1, +100% fully toward 127. Note Length Module - The Length parameter was renamed to Time. - The new Length parameter adds 3 modes, supported only in Note-On trigger mode: Min, Fixed, and Max. - In Fixed mode, the module behaves as before. - Min mode ensures notes last at least as long as the specified value, while Max mode ensures they don't exceed it. - The Sync parameter now supports up to 16 bars. - The module is now more compact. Oscillator Modules - Improved phase control in DS Oscillator, FM Operator, VA Oscillator, and VPS Oscillator. - Phase parameter is now updated in real-time instead of only on note-on. - Can be modulated at slow rates for vibrato or at audio rates for custom PM synthesis. - Phase range shifted from 0º…360º to -180º…+180º, simplifying bipolar modulation. - Added Trigger parameter to control phase on note-on: Free, Retrig, Legato, or Random. - Free: ignores note-on events. - Retrig: resets phase to the Phase parameter value. - Legato: resets phase unless another note is already held. - Rand: assigns a random initial phase. - Updated module UIs to support the new features. - FM Operator: Level parameter range expanded from 0%…100% to -100%…+100%. Reset-to-Zero Envelope - The Amp Envelope module gained a new Reset parameter for controlling reset-to-zero behaviour. - Supports three modes: Off, On, or 1 ms. - Off: On note-on, the envelope restarts from its current value. - On: On note-on, the envelope restarts from zero. - 1 ms: Delays audio by 1 ms and fades it to silence before restarting from zero, enabling clickless voice stealing common in synthesisers. Other Changes - Lane Presets: Add, Insert, and Replace Lane actions now create a new lane with a chosen module in one step. - Noise Module: Renamed the Noise Oscillator module to Noise. - Clipper: Added the "-0.3 dB" preset to the Peak parameter. - Factory Presets: The new "2-Note Symphony" and "Evolving Chord" presets in the MIDI FX group showcase the new features. - Factory Presets: Added the "Based" preset to the Bass group. - Factory Presets: The total number of presets just passed 200.

Module On Parameter - A module no longer dims when it or one of its ancestors is turned off. - The On parameter has changed from a binary type to a continuous one. - It is always a Mono modulation target, even if the module is in Poly mode. - For Group and Stack modules, a submodule's effective On value is the minimum of its own On parameter and its parent's. - Modulators: The On parameter acts as the amplitude of the modulation signal. - Pitch Processors: The On parameter crossfades between the input and the generated Pitch signal. - Audio Processors: The On parameter crossfades between the input and the generated Audio signal. - These changes mean the On parameter no longer causes clicks in audio when changing state. - Since the On parameter no longer disables a module's processing or switches its output between Mono and Poly, it has been removed from modules where it added little value or could cause confusion. - The following modules no longer provide the On parameter: Correlation, Meter, MIDI Capture, MIDI-to-Poly, Oscilloscope, Pitch Oscilloscope, Poly-to-Mono, and Voice Activity. Other Changes - Module Help: Built-in help for all modules has been fully refreshed and is now consistent with Core Concepts terminology. - VA Oscillator: Added the new "Bipolar Triangular Pulse" waveform. - Voice Activity: In Mono mode, the module now resizes to show a single item. - Enter Value: Percentage, decibel, and multiplier units can be used interchangeably. - For example, entering -6dB is equivalent to 50%, while entering 2x is equivalent to +6dB. - Chord Module: The Note On parameters no longer cause the corresponding Pitch and Velocity parameters to dim or become disabled. - Phase Distortion: The module has graduated from Mela Lab and can now be found under the Audio Processor category. - Pitch Oscilloscope: The module has graduated from Mela Lab and can now be found under the Utility category. Factory Presets - Added the "Simple Perc" preset to the Synth FX group, showcasing the new waveform. - Added the "Evolved Perc" preset to the Synth FX group. - Added the "Chorus-Reverb" preset to the Audio FX group. - Added the "LR Sweeps" preset to the Audio FX group.

Pitch Distortion - The Phase Distortion module uses the classic phase distortion technique to reshape any waveform. - It splits the waveform cycle into two parts, stretching the first while compressing the second. - As it is not an oscillator, it relies on the Pitch signal and note-on events (Note signal in Poly mode and MIDI in Mono mode) to determine the waveform's start point and cycle length. - This enables many creative possibilities. - The Pitch signal can be transposed down an octave to distort a waveform an octave higher. - An unrelated Pitch signal can be used to apply phase distortion to a drum loop for unique rhythmic textures. - The Phase Graph visualises the waveform's phase after distortion. - Dragging it horizontally or vertically adjusts the Skew or Tilt parameter correspondingly. - The Curve parameter smoothes the phase rate change at the cycle split point, with higher values producing a mellower sound and reducing aliasing. Pitch Oscilloscope - The Pitch Oscilloscope module visualises audio waveforms, making it ideal for viewing signals from oscillators and other processors. - It uses the Pitch signal and note-on events (Note signal in Poly mode and MIDI in Mono mode) to lock onto the waveform. - A mismatch between the signal and waveform prevents proper tracking. - In Poly mode, it displays the waveform of the last triggered Voice. - It's currently a Mela Lab module and might be integrated into the existing Oscilloscope module in the future. - Pitch Oscilloscope is added to Collection 2 so that users who have the Oscilloscope unlocked will also have this module unlocked. Rectifier Module - Rectifier's new Gate parameter sets the threshold level above which the signal remains unchanged, while everything below it is set to 0. - The Rectify parameter range has been extended to support negative values, which allows modification of the positive portion of the signal. - Rectify parameter now includes a "Full-Wave" preset alongside "Half-Wave". - Drag gesture on the graph now adjusts the Gate and Rectify parameters. - The processing order: Gate Clipping → Asymmetric Gain → DC Offset. Oscillators - The Level parameter of the DS, VA, VPS and Noise Oscillators, as well as the FM Operator, now defaults to 0. - With this change, the Level parameter must be adjusted before the oscillator produces audible output. - The oscillators no longer display a flat line when the Level parameter is set to 0. - DS, VA, and VPS Oscillators now also support the Phase parameter in Mono mode. - This means the phase of these oscillators will reset on MIDI note-on events when no Poly signal is present. Core Concepts - User Guide: The Core Concepts chapter has been significantly improved with unified signal definitions and a detailed explanation of signal flow. - Poly-to-Mono: With the Core Concepts now defining Mono and Poly signal processing modes, the Poly-to-Audio module has been renamed to Poly-to-Mono for consistency. - Signal I/O: A single arrow indicates a Mono signal, while a double arrow indicates a Poly signal. - Note-to-Pitch: The module has been moved from the Pitch Processor category to Signal Router. Factory Presets - Added "RM Side-Chain" preset, which uses a very useful side-chaining technique for drums and bass and demonstrates the updated Rectify module. - Added "Custom Dynamics", "De-Esser", "FB Compressor" and "Upward Expander" presets that utilise the Gain Computer and Gain modules. - Added "Classic PD & Beyond", showcasing the new Phase Distortion and Pitch Oscilloscope modules. - Added "Soft Drift" to the Keys group. - Added "HH Enhance" to the Audio FX group. Other Changes - Parameter Values: Increased spacing between the value and unit to improve readability. - Latency: Reduced the maximum allowed latency from 5 seconds to 1 second. - Audio Output: Fixed an issue in the standalone version where audio stopped outputting when changing the Mac's default audio output device.

Gain Computer - Gain Computer is a modulator module for creating custom dynamics processors. - Depending on its settings and placement in a preset, it can be used to build effects such as a feedback compressor, upward expander, look-ahead limiter, side-chain gate, or de-esser. - It computes gain reduction or expansion from the input audio signal, similar to the gain computer in traditional dynamics processors. - Instead of applying the gain change directly, it generates a modulation signal. - This signal can be used to modulate a Gain module or any other parameter to produce dynamic effects. - The Gain module pairs well with the Gain Computer module, but the modulator supports a wide range of other use cases. - The module includes all the standard dynamics processor controls. - Type Parameter: Selects between Compressor and Expander modes. - Downward Processor: When the Range parameter is set to a negative value, the modulation signal is in the range [-100 %, 0 %], ideal for downward processing. - Upward Processor: When the Range is positive, the signal is in the range [0 %, 100 %], ideal for upward processing. - To learn how to create processors with features found in traditional dynamics tools, check the module help. - Transfer Curve: Shows how parameters affect the transfer function. A horizontal pan gesture adjusts Threshold, a vertical gesture adjusts Ratio. - Oscilloscope: Displays the modulation signal in real time. A horizontal gesture adjusts Attack, a vertical gesture adjusts Release. - Gain Computer is a Mela Lab module and part of Collection 4. Gain Module - The Gain module applies gain to the audio signal. - While designed to pair with the Gain Computer module, it can also be used independently in many other ways. - It has three parameters: Down, Up, and Range. - Although Down and Up use percentage units, gain is applied in decibels. - For example, with Range set to 24 dB, Down at 50 % applies -12 dB gain, and Up at 25 % applies +6 dB. - Gain is a Mela Lab module and part of Collection 4. Latency Support - Added the Ahead parameter to Audio In and MIDI In modules. - The Ahead parameter sets how far in advance Mela requests audio and MIDI events from the host. - This allows processing to begin before the events would normally occur. - For example, it can allow an envelope follower to detect transients before they are heard. - This feature is also referred to as plug-in latency. - Most iOS hosts do not yet support plug-in latency compensation and may ignore this setting. - The "Latency Test" factory preset can help users check DAW support and assist developers with testing and debugging their hosts. User Interface - Modulator Oscilloscope: The view XY-pan gesture now controls one parameter at a time. - Compressor Graph: The view XY-pan gesture now controls one parameter at a time. - Stereo Pan: The Pan and Spread parameter positions were swapped for consistency with other modules. Typically, the parameter below the graph is controlled by a horizontal pan gesture, while the one above is controlled by a vertical gesture. - Mela Lab: Instead of displaying a flask icon in the bottom-right corner, Mela Lab modules now use the flask symbol for the module actions menu. - In/Out Modules: The Audio In, Audio Out, MIDI In and MIDI Out modules are now more compact. - Rectifier: Fixed an issue where the dials appeared visually disconnected from the graph. - Many internal changes to improve the UI engine. Other Changes - Default Preset: Updated the default instrument preset to make it easier to add MIDI Processor modules. - Factory Presets: Added a new effect preset. - Factory Presets: Fixed an issue where the "Digitise Drums" preset would not load. - Preset Browser: Fixed an issue where selecting a preset in a group with many presets would cause the list to scroll up. - Crash: Fixed an app crash caused by receiving an unusually large MIDI packet.

Parameter Presets The Offset parameters have a special behaviour where they can be set to Triplet (~66.7 %) or Dotted (150 %). When selected, a checkmark appears next to the corresponding menu item, and the parameter value field displays the label instead of the numeric percentage. Some parameters also provide "Set to ..." menu items for quickly entering common preset values. These two concepts have now been merged into a unified system called Parameter Presets. - Parameter presets appear above the "Enter Value" item in the parameter's context menu. - When selected, a checkmark appears next to the preset's menu item. - Some presets have custom names. For example, one of the Note Chance module's Chance presets is "1/3", instead of 33.3 %. - You can type the preset name manually to set the parameter to it. For example, enter "1/3" for the Chance parameter. - A preset name may appear in the value field, such as Triplet or Dotted, but not all parameters display preset names. - For example, the Chance parameter displays "1/3" instead of 33.3 %, while the VA Filter's Frequency parameter displays "262 Hz" when the C3 preset is selected. Entering Parameter Values - You can enter values in seconds, milliseconds, hertz, kilohertz, beats, or bars, and they will be automatically converted to the parameter's supported unit. - For example, you can enter delay time in hertz or LFO frequency in milliseconds. - Supported unit suffixes include: "s" for seconds, "ms" for milliseconds, "Hz" for hertz, "kHz" or "k" for kilohertz, "b" for beats, and "B" for bars. For example: "0.5s", "100ms", "440Hz", "1k", "0.5b", "2.25B". - When no unit is provided, frequency defaults to hertz and time intervals default to milliseconds. - You can also enter a MIDI note name, which will be converted to the corresponding frequency. Use "#" for sharp and "b" for flat. For example: "C4", "D#-1", "Gb3". - Time in beats and bars supports fractional input as well as dotted and triplet notation. For example: "4/1", "2/5", "1/4T", "1/8d", "1/3". - By default, the host tempo is used to convert beats and bars, but you can override it using the @ symbol. For example: "1/4t@135", "1.5B@85". - A440 tuning is used by default for notes, but you can override this as well. For example: "G4@400", "C#5@432". Note Stack Module - The Mono module has been generalised into the Note Stack module. - It can now stack more than 1 note, making it useful not just for monophonic but also polyphonic synths. - It can also be used creatively in MIDI Processor chains. - The Play parameter sets the number of notes allowed to be played simultaneously. - When the stack is full and a new note arrives, one of the held notes is released based on the value of the Release parameter. - Release has five values: Old, New, High, Low and Random. - The Wait parameter enables released notes to be brought back when space becomes available in the stack. - The Play and Wait stack views let you visualise both the held notes and the notes waiting to be brought back. Note Pulse Module - The module has a new Mode parameter with three values: Once, Hold, and Loop. - In Loop mode, the module behaves as it previously did, generating pulses at regular intervals. - In Once mode, the module generates a single pulse immediately after each host transport restart. - This is particularly useful for resyncing LFOs. - In Hold mode, the module generates a note-on event when the transport starts and a note-off event when it stops. No other events are generated in between. - This is particularly useful for auto-starting the Euclid module's sequencer. Other Changes - Simple LFO now retriggers on MIDI note-on events when not receiving a Poly signal. - Previously, Simple LFO only retriggered when receiving Poly signals. - Simple LFO behaves as if in Free mode when placed where it doesn't receive note-on events. - Note Range Module: Added new Clamp mode. Notes outside the range are clamped to the nearest note within the range.

Group Module - The Group module is now even more versatile. - The module lets you group a sequence of modules using its sublane. - The signal flow between the containing lane and the sublane depends on the selected mode: Insert, Isolate, Split, or Merge. - The module actions menu icon displays the current mode instead of the ellipsis used by other modules. - Tapping it opens a menu to change the mode and access standard module actions. Insert Mode - The Group module passes its input signals to the sublane and forwards the sublane's output to its output. - Ideal for organising modules. Isolate Mode - The Group module doesn't provide input to the sublane and ignores its output. - The module input and output remain identical. - Ideal for creating an independent sublane that appears inline with the containing lane. - For example, it can be used for generating an envelope follower signal from a side-chain input. Split Mode - The Group module forwards a copy of the input signals to its sublane and ignores its output. - The module input and output remain identical. - Ideal for pre-processing signals before sending them to Audio Out, MIDI Out, or Envelope Follower modules. Merge Mode - The Group module doesn't provide any input to the sublane, but merges the sublane's output signals with the module's input. - The module's MIDI output is a merge of its input and the sublane's output MIDI signals. - The Audio output is the sum of the module's input and the sublane's output signals. - The output signal is Poly only if both the module's input and the sublane's output are Poly. - Ideal for pre-processing signals coming from Audio In, Feedback, or MIDI In modules before merging. Poly Buses - Audio buses in Mela now support Poly signals. - This means the Audio In, Audio Out, and Feedback modules can send and receive Poly Audio signals. - If a bus sender or receiver module isn't receiving a Poly signal as input, the bus signal collapses to Stereo Audio at the receiver before merging with the lane Audio signal. Note Hold Module - The Note Hold module blocks note-off MIDI events and converts every second note-on event of a given note into a note-off event. - Hold Parameter: When turned off, all held notes are released, and new events pass through the module. You can automate or modulate this parameter as needed. - Notes View: The view displays up to 9 held notes. If there are more, an ellipsis symbol appears. - Note Hold is part of Collection 4. Feedback Module - The built-in hard clipper threshold can now be set to +6, +12, or +24 dBFS. - In most cases, +6 dBFS is recommended, but higher thresholds can be useful. For example, when creating a phaser effect with feedback. - The new clip indicator shows when the clipper is triggered. If you're not using clipping creatively, adjust parameters to avoid activation. - The Level parameter range has been changed to [–100, +100] %. - Like the Digital Delay module, it now flushes noise below -160 dBFS to prevent buildup from the digital noise floor. - To prevent a circular dependency, the Feedback module does not collapse the incoming Poly Audio signal even if the signal received from the bus is non-Poly. This differs from the behaviour of the Audio In module. - The module has graduated from Mela Lab and is now under the Signal Router category. Other Changes - Group & Stack: The Mode parameters are now treated as internal, meaning they can't be modulated within Mela or automated from the host. - Lanes: Group modules used as lanes are always in Isolate mode. Turning a Group module into a lane automatically sets its Mode parameter to Isolate. - MIDI Source: In the new "Flip-Flop on Note-On" mode, the modulation signal toggles between 0% and 100% on each note-on event. - Modules: Since modules can be freely renamed, the module type may not always be clear. To address this, the action menu now displays the module's type. - Modules: The add module menu now displays the name of the parent module.

Digital Delay Module - The module has been redesigned and now includes the Delay Path sublane. - Since the sublane provides full flexibility for processing the delayed signal, the built-in 1-pole low-pass and high-pass filters are no longer necessary and have been removed. - To keep levels under control, the module retains the built-in feedback hard clipper that limits the maximum level to +6dBFS. - However, modules like Clipper and Meter can be used to manage and monitor levels in the Delay Path sublane to avoid triggering the clipper. - Existing presets that use the Digital Delay module will automatically migrate, with their sublanes populated by Band Pass and Clipper modules replicating the original filter and clipper settings. - The inserted Clipper will have its Type set to Hard, and Peak to +6dB, while the Band Pass will use the 1-pole filter type. Feel free to adjust these settings or replace the modules as needed. Band Pass Module - The new module processes the Audio signal using a pair of virtual analog low-pass and high-pass filters arranged in series. - It's ideal for creating audio effects with a feedback loop by inserting it into the feedback path. - It offers 1-pole and 2-pole filter modes. - Band Pass is added to Collection 3. Clipper Module - Added the Peak parameter, which sets the clipping level within a range of -18dB to +6dB. - The graph now displays how the positive half-cycle of a sinusoid with unity amplitude is transformed by the module based on the current parameters. - The negative half-cycle is transformed symmetrically. - Dragging the graph horizontally or vertically adjusts the Drive or Peak parameter correspondingly. - Double-tapping the graph resets the parameters to their default values. - The Peak Indicator flashes when the input signal exceeds the Peak parameter value. Stereo Tool Module - The Phase Inverter module has been renamed Stereo Tool and now offers extended routing options. - The module now lets each left/right channel's output be set to match its input, swap to the other channel's input, be phase‑inverted, or muted. - The updated "Ping-Pong Delay" preset utilises this module. Module Improvements - Stack: The module has a new mode, Ring Mod. When enabled, Stack's output Audio signal, or the Audio components of the output Poly signal, is the product of the output Audio and/or the Audio components of the output Poly signals of the submodules. - Stack Module: Fixed the scrolling not working using touch (worked when using a trackpad or mouse). - Lanes: Similar to module menu actions, added the "Replace Lane" action below "Insert Lane". - Feedback Module: Changed Level parameter's range from [-100%, 100%] to [-200%, 200%]. - Feedback Module: To keep feedback under control, the module now has a built-in hard clipper that limits the maximum output level to +6dBFS. - Effect Module: The module graduated from Mela Lab and can be found under the Signal Router category. - Layer Module: The module has been removed since creating the same signal routing is simpler with the Stack and Group modules. - Modules: Submodules now dim when one of their ancestors is turned off. Other Changes - Added the new Black theme to complement the White one. It's based on Martin Breault's MelAUM theme. - More themes can be found on the Artist Themes page: https://nikolozi.com/mela/artist-themes/ - Settings: The Getting Started link has been renamed to User Guide and now opens the guide in the browser. - Voice Alignment: Fixed an issue where MIDI-to-Poly instances sharing the same MIDI input would lose voice allocation synchronisation when one of the instances was unbypassed.

Everything is a Module This update unifies several core concepts. A Mela preset is now powered by a root-level Stack module, containing Group modules as its submodules. In other words, the root-level lanes in a preset are Group modules arranged within this Stack. Lane Improvements - A lane can now be thought of as an instance of a Group module because that's exactly what it is. - Lanes can now be toggled off or renamed just like other modules. - Lanes were redesigned to be more compact. - Lane headers now appear on the left, with titles aligned to module titles and an actions button. - Tapping the title collapses the lane vertically, similar to modules. - Up to 3 collapsed lanes can precede an expanded lane. - If more than 3 collapsed lanes are consecutive, the next expanded lane appears below them. Drag-and-Drop - You now need to grab a module or lane by its header and hover it over a lane header or a module to insert it in front of it. - The dimming effect was replaced with a dashed outline between modules/lanes to indicate the module/lane insertion location. - Since lanes are modules of Group type, they can be dragged over any module to be inserted in front of it. - A Group module can now become a lane by dragging and dropping on a lane header, a new lane will be inserted before it. - If a non-Group module is dragged and dropped in front of a lane, a new lane is created before it with the module inserted. Stack Module - Introducing Stack, the first module that processes its submodules in parallel rather than in series, like sublanes. - The Stack module feeds a copy of its input signals to all its submodules. - The module's output signals depend on the Mode parameter, which has three states: Sum Audio, Merge MIDI, and Passthru. - Sum Audio: Stack's output Audio, or the Audio components of the Poly signal, is the sum of the submodule output Audio and/or the Audio components of Poly signals. - Sum Audio: If Stack's input and all submodule outputs are Poly signals, the module's output will also be Poly. Otherwise, it will be Audio. - Sum Audio: The MIDI signal and non-Audio Poly signal components (unless collapsed) remain the same as Stack's input. - Merge MIDI: Stack's output MIDI signal is a merge of the submodule output MIDI signals. - Merge MIDI: The Audio and Pitch signals, or the Poly signal, remain the same as Stack's input. - Passthru: The submodule outputs are ignored, and Stack's output signals are identical to its inputs. - You may want to process multiple sublanes in parallel for more complex setups. To do this, simply stack Group modules. - With the Stack module, you can create simple MIDI effects, such as converting notes into chords by stacking Transposer modules, or build complex sequencers by combining Group, Euclid, and others. - You can also easily create layered synths or effects. - Stack lets you view submodules individually or as an expanded horizontal stack. - When viewed as a horizontal stack, unlike sublanes, vertical lines replace signal indicator arrows, indicating that the submodules are processed in parallel. - Stack is part of Collection 4 and can be found under the Signal Router category. Crossover Module - The Crossover module splits the Audio signal into frequency bands using second-order crossover low- and high-pass filters. - This makes it ideal for building custom multi-band processors, such as multi-band compressors or distortion effects. - The module's crossover filters are designed to ensure a flat frequency response. - To create a 2-band processor, route the same audio into two parallel instances, set one instance's Band parameter to Low and the other to High, and ensure both have the same cutoff frequency by entering identical numeric values. - To create a 3-band processor, take the output of one of the instances and apply another crossover split, following the same approach. - Crossover is a Mela Lab module and part of Collection 4.

Group Module - The module graduated from Mela Lab. - It has also moved to Collection 0 from Collection 4, meaning it's now unlocked for all users. - Added "Group" and "Ungroup" menu items to the module's actions menu. - Group Action: Moves the module into a new Group module instance. - Ungroup Action: Replaces the Group module with the modules arranged in its sublane. Quantiser Module - The module moves MIDI notes forward to the next grid division for tighter timing. - Sync Parameter: Defines the quantisation grid. - Slack Parameter: Set how far a note can stray from the nearest grid division before quantisation occurs, with no notes moved at 100%. - Pull Parameter: Sets how strongly quantised notes are pulled toward the next grid division, fully snapping them to the grid at 100%. - Note Shift Parameter: When enabled, quantised notes keep their original duration by delaying note-off events. When disabled, note-off events remain unchanged, and notes ending before their quantised start time are removed. - Quantiser is part of Collection 4. Groove Module - The module transforms a straight beat into a dynamic rhythm with accents and a shuffle feel. - Sync Parameter: Sets the timing grid for accents and shuffle. - Accent Parameter: Sets the amount of accent applied to notes at odd grid positions. - Shuffle Parameter: Sets the delay amount for notes at even grid positions, creating a swing or shuffle feel. - Groove is a Mela Lab module and part of Collection 4. Overlap Remover Module - The module shortens an active note when a new note with the same MIDI channel and pitch begins, ensuring the earlier note ends first. - It's useful for preventing an earlier note's note-off event from disrupting a synth's playback of the latest note-on event. - Log: The view displays the last 8 shortened notes. - Overlap Remover is part of Collection 0. Improvements - Feedback Module: Changed Level parameter's range from [0%, 100%] to [-100%, 100%] to allow negative feedback amounts. - Feedback Module: Added the Level parameter, which sets the amount of the feedback Audio signal merged with the signal passing through. - Lanes: Added option to insert a new lane pre-configured with Signal Router modules. - Lane Configurations: Empty, Audio In/Out, MIDI In/Out, Instrument, Mono Instrument, Audio In, Audio Out, MIDI In, MIDI Out. Fixes - Fixed a memory leak caused by the popover menu triggered by the plus button at the end of each lane. - Fixed a rare crash when moving a module from one lane to a sublane of a module in another lane.

The Mela 6.2 is a significant update, making the app fully native on macOS by moving away from MacCatalyst. It offers improved stability on macOS, particularly when used as an AUv3 plug-in within a host. It also introduces three new modules—Layer, Effect, and Group—replacing the Sublane module. Layer Module - Layer module lets you create an audio layer easily using its sublane. - The sublane takes non-Audio signals, MIDI and Pitch or Poly (non-Audio components), as input. - The output Audio signal (or the Audio components of the Poly signal) is the sum of the module's input and the sublane's output. - All other signal types pass through unchanged. - While the sublane can transform a copy of the MIDI and Pitch input signals, those aren't merged at the output, unlike the Audio signals. - The module allows you to create synth layers, where each layer can have independent processors such as filters, amp envelopes, panners, and pitch transposition. - The Volume parameter controls the volume applied to the sublane's output before the Audio signal summing. - Layer is a Mela Lab module and part of Collection 4. Effect Module - Effect module lets you create self-contained custom audio effects. - Its sublane, called Wet Path, receives a copy of the module's input signals. - The output Audio signal (or the Audio components of the Poly signal) is the mix of the module's input and the sublane's output. - While the sublane can transform a copy of the MIDI and Pitch input signals, those aren't merged at the output, unlike the Audio signals. - The Dry parameter controls the level applied to the module's input before the Audio signal summing. - The Wet parameter controls the level applied to the sublane's output before the Audio signal summing. - Effect is a Mela Lab module and part of Collection 4. Group Module - Group module lets you group a sequence of modules using its sublane. - It allows you to move the submodules together or bypass them at once. - The module's input signals are passed to the sublane. - The sublane's output signals are passed to the module's output. - Group modules can be nested. - Group is a Mela Lab module and part of Collection 4. Improvements - Glide: The module now handles non-Poly signals, i.e. it functions properly when following a Note-to-Pitch module. - Oscillators: The VA and DS Oscillator modules, along with the VPS Oscillator, will no longer animate changes to the Level parameter, except when its sign changes (positive to negative or vice versa). This adjustment improves visibility, as it’s harder to observe how other parameters influence the waveform shape when the Level is near zero. - DS Oscillator: The module now has the same layout as the VPS Oscillator. - DS Oscillator: The module now handles zero pitch signal gracefully. - Preset Browser: On macOS and iPad, you can now secondary-click on a preset to show the context menu instead of the long-press gesture. - Presets: When the plug-in state is saved or loaded, the "name" field now sets or retrieves the preset name. This ensures that in hosts like Logic Pro, which store presets outside Mela’s file container, the name shown in Mela matches the name of the preset loaded from the host. - UI: Removed the close buttons from the popovers, as they were redundant. Tap/Click outside to dismiss them. - UI: The About view is now a popover and follows the zoom setting. Fixes - MIDI Delay: Fixed a bug where MIDI messages were delayed by twice the amount of the set tempo-sync value. - Preset Browser: Fixed a bug where long-pressing a preset shown in search results would sometimes display a wrong context menu. - Polyphony: Fixed an issue where the Reuse and Release settings were not set in the audio engine. - Polyphony: Fixed MIDI-to-Poly's voice alignment not working for the same MIDI input in some cases. - Modulation: Fixed modulation not working correctly for the modules inserted after a module causing a Poly-to-Audio signal collapse.

Collection 4 - Mela's modular capabilities are expanded by introducing Collection 4 with powerful new modules for advanced sound design. - The centrepiece is the Sublane module, enabling nested processing for flexible signal routing. - Also included are the MIDI Delay and Note Pulse modules, adding temporal and rhythmic control to your MIDI. - Modules like Delay and Feedback let you create custom multi-tap delays, comb filters, and physical modelling effects. - To streamline your workflow, the Vel-to-Amp module maps MIDI velocity to amplitude, while the Note-to-Pitch module converts MIDI notes into a pitch signal. - Every Mela 6.x update will add new modules to the collection. You only need to purchase it once. Mela Classic vs Mela - With this update, the major version number has been dropped from the name—so instead of Mela 6, the app is now simply called Mela. - This change helps avoid confusion, as some users mistakenly thought Mela 6 was a separate app rather than an update to Mela 5. - To clarify: Mela 4, 5, and 6 were all the same App Store app, just with different version numbers in the name over time. - Meanwhile, Mela 3, which is a separate App Store app, will be renamed to Mela Classic. Sublane Module - Sublane is a module that contains a lane of modules, aka sublane. - Modules with sublanes can be nested inside each other. - Input Parameter: When enabled the module input signals will be passed to the sublane. - Output Parameter: When enabled the sublane output signals will be passed to the module output, otherwise, the module output will be the same as the input. Delay Module - The module delays audio signals by a specified amount. Compatible with Poly signals. - Time Mode: Set the delay time in seconds. - Synced Modes: Set the delay time using tempo-synced values. - Pitch Mode: Set the delay time based on the input pitch signal frequency. Ideal for creating comb filters or physical modelling effects. - Offset Parameter: Adjusts the delay time by 50-200%. Available in Pitch and tempo-synced modes. Feedback Module - In Mela, signals flow left-to-right within a lane and top-to-bottom between lanes. - However, you may want to send an Audio signal in the opposite direction to create feedback. - The Feedback module allows you to do just that by taking the output of an Audio bus, delaying it by 1 sample, and merging it with the Audio signal passing through the lane. - WARNING: Protect your ears and equipment by handling feedback with care. Ensure feedback does not build up continuously. MIDI Delay Module - The module delays the MIDI signal by a specified amount. - Time Mode: Set the delay time in seconds. - Synced Modes: Set the delay time using tempo-synced values. - Offset Parameter: Adjusts the delay time by 50-200%. Available in tempo-synced modes. Note Pulse Module - The module generates note-on and note-off events at regular intervals, synchronised with the host transport. - Events are generated only when the transport is running. - The parameters Sync, Gate and Offset let you set the timing of the pulses. - Additional parameters allow you to set the generated note event's channel, note, and velocity values. Note-to-Pitch Module - The module converts MIDI notes into Pitch signals. - If an instance of MIDI-to-Poly is inserted, this module is not required unless you wish to change the tuning from the A440 pitch standard. - Tuning Parameter: Sets the tuning of the note A above middle C. Vel-to-Amp Module - The module uses MIDI note velocity to control the audio level, making notes velocity-sensitive. - Supports both Audio and Poly signal types. - Curve Parameter: Adjusts the velocity-to-amplitude mapping. Higher values increase loudness, while lower values provide more dynamic range. - Smooth Parameter: Sets the time constant for smoothing level changes between notes. There’s more in this update, but I hit the character limit. Full details: https://nikolozi.com/mela/changelog

Mela 6.0 kicks off a new chapter in the app's evolution, starting with unifying all lane types into a universal one for greater flexibility. The updated Getting Started guide explains how key concepts have evolved—be sure to check it out, along with the changelog, for a quick overview. This is just the beginning, with much more to come in the upcoming 6.x updates. Universal Lane - All lane types (Audio, MIDI, Instrument) are now unified into a single universal lane with merged capabilities. - The preset migrator automatically converts existing presets to use universal lanes. - Lane audio and MIDI I/O settings are replaced with Signal Router modules. - Signal Routers: Audio In, Audio Out, MIDI In, MIDI Out, MIDI-to-Poly, and Poly-to-Audio. - These modules are part of Collection 0. Audio In/Out Modules - Audio In receives Audio signals from the host or an Audio bus. - Audio Out sends Audio signals to the host or an Audio bus. MIDI In/Out Modules - MIDI In receives MIDI messages from the host or a MIDI bus. - MIDI In includes a "Panic!" button to send "All Notes Off" MIDI messages downstream on all channels. - MIDI Out sends MIDI messages to the host or a MIDI bus. - MIDI Out a "Panic!" button to send "All Notes Off" MIDI messages on all channels to the output. MIDI-to-Poly Module - The module converts MIDI messages into a Poly signal, replacing any existing Audio or Poly signal with a new Poly signal. - The module lets you set the polyphony settings for the preset. - Instances sharing the same MIDI input synchronise voice allocation, ensuring consistent Poly-to-Poly modulation across modules. - The Voice Priority rule is replaced with a "Release" setting, clarifying how voices are reallocated for new notes. - Previously, this functionality was handled implicitly by the Instrument lane type before sending the Poly signal to modules. Poly-to-Audio Module - Collapses a Poly signal into an Audio signal by summing voices while retaining the last note-on Pitch signal. - Modules that don't support Poly signals automatically perform this collapse. - The signal remains collapsed even if the collapsing module is bypassed. - Previously, this functionality was handled implicitly by the Instrument lane type before sending the Audio signal to its output. Module Updates - Amp Envelope: Now mirrors the behaviour of the Envelope Generator. When no Poly signal is present, it uses MIDI signals to trigger attack and release states, shaping the Audio signal accordingly. - Panic Module: Removed, as the functionality is now integrated into the MIDI In and MIDI Out modules. - Voice Activity: Now displays Audio signal levels and MIDI signal's last note and velocity when no Poly signal is present. - Voice Activity: Now automatically resizes based on the preset polyphony. - Modulators: The "Targets" view no longer scrolls to the bottom on appearance. Improvements - Getting Started: Updated to reflect the latest changes. - Notepad: Renamed the Note Pad module to Notepad. Fixes - Module Help: Fixed the help popover not utilizing available space correctly. - Preset Load: Resolved a crash that occurred under certain conditions when changing presets. - Polyphony Settings: Fixed an issue with the Newest Release mode not initialising correctly. - Modulators: Modules without parameters, such as Notepad, no longer appear as modulation targets.

Factory Presets - DC Ring Bass: Demonstrates how to turn the Ring Mod module into an oscillator by feeding it a DC signal. - Audio-to-ADSR: Demonstrates how to convert audio signal levels into note events to drive an envelope generator. - Event Symphony: Demonstrates how to use Random and Note Event module instances to create generative music. - Other Presets: Church Bells, Consistent, Drum Bus, Stereo Wah Wah, Tuned Noise + FM, and Tuned Noise + FM 2. Improvements - Collections: Updated the description for Collection 3. Fixes - Reverb: Fixed a bug where the HSF Decay parameter wasn't initialised correctly in DSP. - UI (macOS): Fixed a bug where the selected modulation target menu item displayed two checkmarks. - UI (macOS): Fixed a bug where locked modules incorrectly displayed two shopping carts under the insert module menu.

- MIDI Source: Note-On/Off Gate source is now velocity-sensitive. - Mela Lab: Graduated Euclid, Note Chance and Pitch Follower modules. - Factory Presets: Removed the Mela Lab group and redistributed its presets to the other groups. - Factory Presets: Added new presets that showcase the Euclid module. Search for "Euclid" in presets. - Correlation: Fixed errors in measurement due to numerical rounding errors. - Reverb: Fixed a bug in the diffuser algorithm. As a result, the reverb should sound much better.

- MIDI Capture: Fixed a crash caused by the module after pressing the Start and Stop buttons several times. - Voice Activity: Fixed a crash caused by the module when modifying the preset while keys were held. - Pitch Ratio: Fixed an intermittent crash caused by the module on initialisation. - Pitch Ratio: Replaced the default 1/1 ratio with a more interesting 3/2 ratio value.

Euclid Module - The module converts incoming MIDI notes into Euclidean rhythm. - The core idea behind Euclidean rhythms is arranging a given number of events as evenly as possible in a pattern. - The Steps, Pulses and Rotate parameters let you configure the pattern. - The Accents, Shift and Velocity parameters let you configure the accented events. - The Gate and Sync parameter lets you configure timing. - The circular sequencer view lets you visualise the resulting pattern and the current step. It reduces the Accents, Pulses and Steps to coprime values. - The module works well with Arpeggiator – insert it before Euclid and set the Retrig parameter off. - The Arpeggiator module now defaults to Retrig mode off on instantiation so that the timing is aligned with the Euclid module when inserted one after the other. - When combined with the MIDI Source’s Note-On/Off Gate mode the rhythm can be turned into a modulation signal. - Euclid is a Mela Lab module and part of Collection 3. Pitch Follower Module - Pitch Follower is a polyphonic modulator that generates a modulation signal based on the input pitch signal. - It's similar to the MIDI Source's Key Track, but instead of following MIDI notes, it precisely tracks the pitch signal, including pitch bends. - A change in the pitch signal by an octave results in a 10% change in the modulation signal. - The Center parameter sets the modulation's zero point — when the input pitch matches this frequency, the modulation signal is at 0%. - To make it easier to modulate the Frequency parameters of All Pass, Comb Filter, EQ Band and VA Filter modules with Pitch Follower, they now offer "Set to" menu items with 261.6256Hz (middle C) and 624Hz (range mid-point) values. - The module can be used in both Instrument and Audio lanes. - Pitch Follower is a Mela Lab module and part of Collection 3. Correlation Module: - The module helps you visualise the correlation between the left and right channels of the audio signal passing through it. - Generally, keeping signals above 0 is best. A 0 value represents an extremely wide stereo image. - When the indicator is closer to +1, the channels are highly correlated with little side content. - If it gets closer to -1, the channels are out of phase, leading to most of the signal cancelling out when summed to mono. - Correlation is part of Collection 3. Mute Button - The Level module now features a Mute toggle, linked to the Level parameter. - When muted, the Level is set to 0%. - Unmuting restores the Level to its previous value. - Use the Level module for quick, clickless muting of a lane or part of a lane. Stepper Control - Added a stepper style control, it's ideal for a list or integer-valued parameters. - It consists of two buttons around a parameter title/value button. - Tapping on them sets the parameter to the previous or next value. - Dragging these buttons vertically allows you to adjust the values faster. - The behaviour is similar to dials and sliders that control list type parameters, they trigger the value change on release. - The first modules to utilise stepper controls are Euclid and Pitch Ratio. Improvements - Chord: Simplified the module by removing the note toggle label, making it more compact. - Chord: Changed the maximum number of notes in the chord from 6 to 8. - Chord: Added "Set to" menu items to the Pitch parameters. - Pitch Ratio: The module now uses stepper controls for the Numerator and Denominator parameters, simplifying incremental value adjustments. - Pitch Ratio: The Ratio Display now updates when the module parameters are modulated, displaying the resulting ratio multiplier. - Rectifier: The Rectify parameter now offers a "Set to" menu item with the value 50%. - Comb Filter: The Frequency parameter now defaults to 624Hz, the mid-point of the parameter range. - Drag-and-Drop: Dragging modules onto empty lanes now works. - Settings: Added the link to the tutorials page under the Help section.
