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.

Note Chance Module - The module allows MIDI notes to pass through based on a specified probability. - The Chance parameter sets the probability. - At 0% Chance, all notes are blocked; at 100%, all notes pass through. - The log view displays the last 7 processed notes, indicating whether each was blocked or passed. - Ideal for generative MIDI chains and adding controlled randomness. - Example: Modulate Chance using MIDI Source with its input set to Velocity to allow notes with higher velocities to have a higher chance of passing through. - Note Chance is a Mela Lab module and part of Collection 3. Random Module - The Random module is now more powerful with new modes and the Tilt parameter. - The Mode parameter sets the random signal generation algorithm: Random I, Random II, or Chance. - Random I: At 0% Tilt, the modulator signal randomly takes a value within the set range uniformly. Increasing Tilt toward +100% makes higher values more likely while decreasing Tilt toward -100% makes lower values more likely. - Random II: At 0% Tilt, the modulator signal randomly takes a value within the set range uniformly. Increasing Tilt toward +100% makes extreme values more likely while decreasing Tilt toward -100% makes values near the midpoint more likely. - Chance: At 0% Tilt, the modulator signal randomly takes the maximum or minimum value with equal likelihood. Increasing Tilt toward +100% makes the maximum value more likely while decreasing Tilt toward -100% makes the minimum value more likely. Tuned White Noise - The Noise Oscillator module now includes a new Tuned noise type. - It follows the input pitch signal by downsampling white noise. - The sampling rate is 8 times the input pitch frequency, creating a pitch-tracking noise effect. Preset Search - Mela now supports preset search for both user and factory presets. - The search field is located above preset groups in the Preset Browser. - Tap the search field to begin searching. - If the Preset Browser is closed, selecting Preset Search from the Preset Selector's action menu will open it and focus the search field. - In the standalone version, you can also use Command-F to do the same. Improvements - Degrader Module: Added a "Set to" menu item with the value 2093.00 Hz (3 octaves above middle C) to make it easier to create pitched noises using the Noise Oscillator module and MIDI Source's Key Track. - Modules: Improved the random number generator algorithms. - Module Help: Improved clarity of some parameter descriptions. - MIDI Logger: Made the log background more prominent. - Note Pad: Made the text background more prominent. - Parameter Values: The internal number formatter now overrides the system locale by disabling the grouping separator. - Parameter Values: When manually entering parameter values, both period and comma will be treated as decimal separators regardless of the system locale. Fixes - Preset Browser: If closed, the Create Group keyboard shortcut now opens the browser as expected. - MIDI Source: Fixed visual indicator drawing incorrectly for the Key Track input for MIDI values above 120.

- Fixed a launch crash caused by Mela attempting to preselect a previously used preset group that no longer exists.

Reverb Module: - Introducing a high-quality algorithmic reverb module. - Features standard controls such as room size, decay amount, predelay, and mix. - Offers independent controls for early reflections and diffusion levels. - Includes a high shelf filter in the feedback path to control high-frequency damping. - The module's feature set will evolve in the lab. - Early feedback is encouraged to help shape its future development. - Reverb is a Mela Lab module and part of Collection 3. Ring Mod Module: - Inspired by analog ring modulator circuits. - Produces richer harmonic sound compared to pure digital ring modulation. - The module's input acts as a modulator to the sinusoid carrier. - The carrier frequency ranges from 8Hz to 8192Hz, spanning exactly 10 octaves. - Using the MIDI Source module, it's easy to make the carrier frequency follow MIDI notes. - The Character parameter adjusts the tonal quality of the ring modulation. - Lower values tend to create a mellower, smoother sound, whereas higher values produce a harsher, more intense sound. - The "Ring Bass" and "Ring Follower" presets showcase the module in action. - Reminder: for pure digital ring modulation, use the VA Oscillator module's built-in ring modulation feature. - Ring Mod is part of Collection 3. Other Changes: - Moved the Note Pad module from Collection 3 to Collection 0, unlocking it for all users. - Graduated the Noise Gate module from the Mela Lab, it's now under the Audio Processors category. - Slightly tweaked the All Pass module layout. - EQ Band layout is now more compact and similar to All Pass. - Fixed EQ Band's High Shelf cut not processing audio correctly. - Improved EQ Band module's DSP algorithms. - Fixed the Digital Delay module not initialising correctly. - Digital Delay will no longer build up feedback from the noise floor. - Stereo Delay no longer causes a crash when one of the delay times is set to 0 seconds. - Fixed the max peak value label alignment in the Meter module that the 5.4 update broke. - Fixed the Preset Browser sometimes not preselecting the last used preset group on Mela plug-in instantiation. - EQ Band Gain parameter now offers "Set to" menu items with values -6dB, -3dB, +3dB, and +6dB. - Oscillator Phase parameters now offer "Set to" menu items with values 90º and 180º. - Fixed the Compressor and Gate parameters not being smoothed. - Updated some presets and added new ones. GarageBand for iOS Compatibility: - The Mela 5.5 update introduced side-chain audio input when loaded as an instrument plug-in. - This change broke compatibility with GarageBand for iOS, where Mela wouldn't produce any sound when instantiated as an instrument plug-in. - This update reverts that change to restore compatibility. - Side-chain support for the instrument mode will be added back once the issue is fully investigated and addressed. - In the meantime, you can still use a side-chain with synth presets by loading Mela as an effect. - For example, in Logic Pro, select and load Mela from the MIDI-controlled Effects menu.

All Pass Module: - The new module allows all frequencies to pass through without attenuation, while introducing varying phase shifts. - It includes first- and second-order filter types. - The first-order type shifts the phase by 90º and the second-order by 180º at the cutoff frequency. - The module is ideal for creating audio effects such as phasers. - The All Pass Phaser preset, found in the Audio FX group, demonstrates the module's functionality. - All Pass is part of Collection 3. Other Changes: - Mela now supports side-chain audio input when loaded as an instrument plug-in. - The side-chain signal comes through Audio In 1 for the instrument plug-in, but when Mela is loaded as an audio effect plug-in, it comes through Audio In 2. - Increased the number of supported lanes in a preset from 8 to 16. - The XY control has been simplified. The independent X and Y handles are gone, and the entire control area responds to touches, improving the experience for live performances. - Updated the UI layouts of the following modules: Distortion, DS Oscillator, MIDI Source, Rectifier, VA Filter, VA Oscillator, and VPS Oscillator. - Removed the on/off switch from the Panic module, as it served no purpose. - If purchasing is disabled on your device due to Content & Privacy Restrictions or a Mobile Device Management profile, Mela's In-App Purchasing view now displays a warning. - Fixed a bug where Digital Delay synced delay times didn't follow the host tempo. - Fixed truncated parameter labels for DC Offset in the Rectifier module and Asymmetry in the Distortion module at certain zoom levels. - Fixed a bug where some UI components wouldn't switch to the light or dark scheme correctly in AUv3 mode. - Fixed a bug where MIDI Logger's content wasn't scrollable. - Fixed position value formatting in the MIDI Logger module. - Added new presets. - Made many small internal improvements.

Noise Gate Module: - Added a fully featured noise gate module with a gain reduction meter. - It provides the following parameters: Threshold, Hysteresis, Reduction, Attack, Hold and Release. - Noise Gate is a Mela Lab module and part of Collection 3. Module Updates: - Added the Parabolic Sine waveform to the VA Oscillator module. - Added the Cycles parameter to the Random module. Set its value to 1 for one-shot behaviour. - Added the Smooth parameter to the Random module. It defines the time constant for smoothing out the random modulation signal. - For consistency, the Smoothing parameter has been renamed to Smooth in the following modules: Macro Button, MIDI Source and Stereo Delay. - Added the Step waveform to the Simple LFO module. It's a unipolar version of the Square waveform. - Macro Button's Smooth parameter's maximum value changed to 1 second from 100ms. - Macro Button has graduated from the Mela Lab and can be found under the Modulators category. - The MIDI Source's UI is now slightly more compact. Other Changes: - Moved the Mela Lab button to the right to improve the toolbar layout. - Added new presets. - Various internal improvements.

- Added a Mela Lab preset group which will be used to demo Mela Lab module features. - Added Demo 5.3 preset to the group. - Mela Lab modules no longer incorrectly display the flask icon when not expanded. - Fixed the preset overwrite confirmation dialog sometimes dismissing itself, preventing saving the preset. - Fixed the incorrect alignment of the close button of the About screen when Mela zoom was set to a value other than 100%.

Mela Lab: - Introducing the Mela Lab module category. - From time to time new modules are added to the Mela Lab category without any future promises, meaning their feature set is subject to change. - This freedom allows for the experimentation and exploration of new ideas. - With every update, the modules will be refined. - Once a module proves useful enough, it will become part of Mela. - Some experiments will not produce desirable results, and those modules will be removed. - Contribute to the process by submitting feedback to help with the evolution of these modules. - Always remember to bounce down audio and MIDI parts of your projects that utilise Mela Lab modules, as their behaviour may change from version to version, potentially altering the sound of your tracks. - When a preset uses at least one Mela Lab module a flask icon appears in the toolbar. - Tapping it will present the Mela Lab Help view. - Mela Lab modules display a small flask icon at the bottom right corner. Macro Button Module: - It's a modulator module similar to the Macro module but uses a toggle button instead of a slider. - The toggle button is linked to the Macro parameter. - When the toggle is off, the modulator signal is at 0%, and when it's on, it jumps to 100%. - Transition between these binary states can be smoothed by adjusting the Smoothing parameter. - Macro Button module's Macro button (and now also the Note Event module's Event button) triggers on touch rather than release. - Toggling between the previous and new states can be done by sliding the finger in and out of the button area, allowing performance-oriented usage. - Macro Button is a Mela Lab module and part of Collection 3. Multiply-Add Module: - It's a modulator module whose modulation signal is equal to A×B+C where A, B and C are the values of the module parameters. - Modulate some or all three parameters to create complex signals. - The module supports polyphonic modulation. - Multiply-Add is a Mela Lab module and part of Collection 3. Audio-to-Mod Module: - It's a modulator module whose modulation signal is the average of the left and right channels of the input audio. - As all modulations happen at sample rates in Mela, feel free to modulate any parameter to create interesting sounds. - For example, modulating a level of another oscillator will result in Amplitude Modulation (AM) synthesis. - Modulating the cutoff frequency of a filter will result in FM synthesis. - The module supports polyphonic modulation. - Audio-to-Mod is a Mela Lab module and part of Collection 3. Text Input: - The module renaming action no longer presents a separate text field for entering a new name. Instead, the label turns into a text field in place. - The preset and preset group renaming actions no longer present a separate text field for entering a new name. Instead, the label turns into a text field in place. - The "Set to" menu items now correctly format parameter values with units. - Some of the parameters of Comb Filter, LFO, Pitch Bend, Random, Relative Pitch, Transpose and Volume modules now offer useful "Set to" menu items. - Musical Keyboard now hides when iOS's typing keyboard appears in order not to get in the way. Other Changes: - Added the Cycles parameter to the LFO module. Set its value to 1 for one-shot behaviour. - Moved the Create Group menu item from the Preset Selector to the User and custom groups' actions menu. - The preset management help information is now accessible via the Preset Selector's actions menu. - It's much more concise and has been removed from the Getting Started with Mela document for simplicity. - Added new presets. - Fixed a preset loading bug causing some parameters to initialise incorrectly.

Preset Selector: - Moved the Preset Selector to the left side of the screen. - Added disclosure button to toggle the Preset Browser view. - Tapping the preset name now presents the actions menu, removing the need for a separate button. - The Save Preset, Export & Save and Create Group actions no longer present a separate text field. Instead, the Preset Selector turns into a text field in place. - Now a confirmation dialogue will be displayed when overwriting an existing preset. - Create Group action is now accessible via the File menu or Command-G shortcut in the Mela app. Preset Browser: - Greatly improved Preset Browser interface, now vertically scrollable on the left side. - It now feels more integrated with the Preset Selector. - The Import, Export, Rename, and Delete preset group actions are accessible via the ellipsis icon menu. - User presets offer similar actions through a long-press gesture (or right-click on macOS) and swipe left on the preset name. Event Module: - Introduced a new MIDI Processor module for note-on and note-off events. - It's simple yet very versatile. - With the Event module, you can create algorithmic compositions by modulating its parameters. - It can trigger envelopes or retrigger LFOs, even when Mela is inserted as an audio effect with no MIDI input. - Events can be triggered via the user interface, automation, or modulation. - Its primary parameter, Event, accepts values within the [0%, 100%] range. - When the value exceeds 50%, the module generates a note-on event. - Once the value drops to 50% or lower, it generates a corresponding note-off event. - Additional parameters allow you to set the generated event's channel, note, and velocity values. - The note-on and note-off events can also be triggered by tapping the toggle button. - The toggle button indicates the currently held note. - The Event module is part of Collection 3. Note-On/Off Gate: - It's now possible to create a gate-like modulation signal using the MIDI Source module based on note-on and note-off events. - Set the Input parameter to Note-On/Off Gate to use it. - On note-on, the modulation signal jumps to 100% but it drops back to 0% on note-off. - The signal can be smoothed out using the Smoothing parameter. - You can use this instead of an envelope generator when you don't need the complexity. Text Input: - The Perform View parameter renaming no longer happens in a separate text field. Instead, the value label turns into a text field in place. - The Enter Value menu action and a triple tap on a dial or slider no longer display a separate text field for entering a parameter value. Instead, the value label turns into a text field in place. - For frequency-based parameters, you can now enter values by appending either "kHz" or "k". Mela will interpret these values as kilohertz instead of assuming they are in hertz. - Similarly, for time-based parameters, appending "s" to the value will indicate to Mela to use seconds instead of the default milliseconds unit. - Added "Set to 0%" menu item above Enter Value for the Level parameters of the oscillator modules. - The Level parameter of these modules reset to the default value of 50% on double-tap, however, the 0% value is also very useful (e.g. for amplitude modulation). - In the future, other parameters may gain similar options to quickly set them to common useful values. Other Changes: - The update includes many internal changes to continue to transition away from Mac Catalyst and towards becoming a fully native macOS app. - The MIDI Source and Note Length modules updated the Note-on/off strings to Note-On/Off to improve consistency. - The MIDI Logger module is now more compact as the Copy and Clear buttons were removed. The actions are still available via the context menu which can be accessed by tapping the console anywhere. - Added a workaround for Musical Keyboard getting stuck notes due to SwiftUI gesture bugs. - Many UI tweaks and improvements.
