All notable changes to this project will be documented in this file.
- Fix GUI issues when using the clap plugin in Bitwig
- Fix issue with activating operator 2 modulation target from GUI modulation matrix
- Show file save/load dialogs on top of plugin window on macOS
- When saving patch bank/state, also save selected patch index (and restore it on load)
This release contains breaking changes. Voice phases are reset when they end, which can audibly impact existing projects.
- Add monophonic voice mode (only once voice active at a time). In this mode, when envelopes are restarted, attack will proceed from the previous volume, not from zero
- Add glide (portamento)
- Available for both polyphonic and monophonic voice modes
- Can be set to OFF, LEG (only glide when playing legato) or ON (always glide)
- Supports linear constant time (LCT) and linear constant rate (LCR, time per octave) modes
- Supports optional BPM sync for time/rate
- Optionally retrigger envelopes and LFOs when gliding in monophonic mode
- Replace patch settings overlay with button for toggling alternative visible controls
- Reset voice phases when they end. This fixes an issue where subsequent key presses without intermediate parameter changes do not result in identical sounds.
Audio output is not bit-for-bit identical to version 0.8.6, but there should be no audible differences.
- Add velocity sensitivity parameters, i.e., parameters for how key press
velocity affects:
- Final voice volume
- Modulation output (per-operator)
- Feedback (per-operator)
- Add parameter tooltips for better discoverability
- Change layout of bottom right corner and make plugin window 12 pixels wider to accommodate new controls.
- Add LFO key sync parameter, controlling initial phase of LFOs when activated by a key press. With the default of value of "on", the phase starts at zero. When value is set to "off", the LFO will instead start at a random point of the wave cycle.
- Add pitch bend support. Parameters for upwards and downwards semitone range are accessible from the patch action dropdown menu.
- Add square, triangle and saw operator waveforms. Patches created with previous versions should load from files perfectly. DAW projects should load perfectly in most cases, but if you've used automations on the waveform parameter, the effect will not be the same as before.
- Fix crashes on Windows when clearing patch bank or patches
- Display file pickers on top of plugin window on macOS
- Implement clap state extension
- Use new patch bank / patch format with better provisions for forward compatibility. Patches created with previous versions are automatically converted when opened.
- Upgrade to iced v0.8
- Make CLAP plugin GUI work in Bitwig on Windows; it still doesn't work in Bitwig on macOS and only sometimes on Linux
- Fix clap miscompilation on Linux on aarch64
- Add initial clap plugin support
- Upgrade to iced v0.7
- Fix crashes when opening GUI
- Support sustain pedals (MIDI CC 64)
- Upgrade to iced v0.6, including partly rewriting iced_baseview.
- Improve detection of when mouse cursor hovers over envelope draggers
This release features native Apple Silicon support, performance improvements and bug fixes, including making parameters automatable in Bitwig Studio and Carla.
Audio output is not bit-for-bit identical to version 0.8.0, but there should be no audible differences.
- Add Apple Silicon support. The macOS release is now built as a universal binary
- Improve performance by around 10% in many cases by improving CPU cache behaviour in audio generation
- Port several SLEEF functions to Rust to avoid relying on undefined behaviour, remove the need to use a nightly compiler and ease cross-compilation, e.g., for Apple Silicon. Unfortunately, performance of these functions is decreased somewhat.
- In audio generation, skip extracting voice data if envelope is ended
- Update dependencies
- Fix bug where plugin didn't properly tell host about automatable parameters, causing them not to be picked up by Bitwig, Carla and possibly other hosts
- Tweak audio gen to fix (very minor) differences between simd widths
- When envelope ends, set voice operator phase to 0.0
This release features revamped stereo panning, shorter minimum envelope stage lengths, improved patch management, displaying of waveforms and various fixes.
This release contains breaking changes. Patches might not be able to be fully migrated. However, in many cases, importing patches from 0.7.0 and doing two changes will work:
- Setting
mod outvalues to 0.7071 of what they previously were - Setting LFO targets to the correct value (they may have been changed)
You can keep version 0.7.0 alongside this release, since they use different VST2 plugin IDs.
- Display (part of) left and right channel waveforms for all operators
- Add patch section dropdown with actions for opening patch/bank files, saving patches/banks, renaming patches and clearing current patch/bank
- Add functionality for setting parameter values exactly. Click on values to display a value input window.
- Reintroduce master volume and master frequency parameters as LFO targets (removed in version 0.7)
- Rework panning
- Use true stereo panning (not just balance) for mix and modulation output
- Stop using constant power panning for modulation output. Previously, when
an operator was panned to the center, its modulation output would scale at
cos(π/4)(approximately 0.7071) the rate of feedback but at the same rate when panned hard to a side, which is not very intuitive.
- Decrease minimum envelope stage duration from 10ms to 3.33ms
- When note off message is received during envelope attack phase, always go to release phase, even if it means that with low sustain volumes and a long release time, short notes might be loud for a lot longer than longer notes. This is how FM8 envelopes work.
- When note off message is received during envelope decay phase, go to release phase
- For LFOs in oneshot mode, after running once, stay at the end value instead of going back to zero
This is a large release featuring lots of changes. Some major ones include:
- Full interface redesign for a more modern look
- Operators can now modulate multiple targets. Routing parameters were updated to be more intuitive
- LFOs were redesigned to be easier to work with
- Envelope groups were implemented for adjusting multiple envelopes simultaneously
- Operator and LFO mute buttons were added
This release contains breaking changes. It is not compatible with patches created with previous versions. However, you can keep using version 0.6.1 alongside this release, since it uses a different VST2 plugin ID.
- Allow operators to modulate multiple carriers
- Set modulation index (mod out) in modulator, not carrier
- Increase range of feedback parameter to match modulation index
- Replace additive factor with mix out parameter, which doesn't affect modulation output
- Update frequency ratios, adding both harmonic and disharmonic ones
- Update free frequency parameter values
- Add operator mute parameter
- Feedback is now affected by key velocity
- Interpolate key velocity if key is pressed while envelope is still active
- Fix various envelope issues
- Remove ability to set end volume of attack (it is now always at maximum)
- Increase minimum envelope stage length to 10ms
- Use a more traditional LFO design that oscillates around the base value, not in a single direction.
- Scale LFO effect linearly and bypass normal parameter limits when targeting master frequency, master volume, operator free frequency, operator volume, LFO amount (magnitude) or LFO free frequency parameters
- Make LFO triangle wave type start at value 0.0
- Add LFO wave types reverse triangle, sine and reverse sine
- Default to no target
- Remove master volume and master frequency targets, since LFOs are really per-voice
- Add LFO mute parameter
- When BPM sync is turned off, use base frequency of 1 Hz
- Update master frequency parameter values
- Use time-based instead of sample-based interpolation for parameters and LFOs for sample rate independence
- Major GUI redesign with layout and color changes
- Add envelope group functionality, enabling simultaneously editing multiple ones

This release contains breaking changes, i.e., changes that can affect how patches sound.
- When triggering note while envelope is still running, restart envelope from zero volume
