Mela 5 – AUv3: Synth, FX, MIDI 4+

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.
