5.8

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.
  • Getting Started: Updated the document.
Fixes
  • Arpeggiator: Removed redundant note-off messages sent out by the Arpeggiator module.
  • Toggle Control: Fixed a bug where performing the cancellation gesture on the control wouldn't cancel and still toggle the state.
  • Getting Started: Fixed external URLs not opening in Safari.

5.7

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.

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.

5.5

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.

5.3

Mela Lab:
  • Introducing the Mela Lab module category.
  • From time to time new modules will be 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.
Mela 5.3
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.
