tune

• New: Define and import keyboard mappings via microwave ref-note or microwave kbm-file

• Improvement: Calculate the errors and badness of an equal-step tuning
• Improvement: Make the diff command consistent with the remaining commands

• Improvement: Calculate the errors and badness of a Val
• Improvement: Improve the error structs and the documentation of the scala module
• Change: Move ChannelMessage::transform to ChannelMessageType::transform for consistency

The live retuning feature has been rethought. You can now combine different tuning methods, tuning modes and tuning clash mitigation strategies.

Available tuning methods:

• [new] Full keybord / Single Note Tuning Change
• Octave-based / Scale/Octave Tuning
• [new] Channel-based / Channel Fine Tuning
• Channel-based / Pitch-Bend

Available live retuning modes:

• Ahead-of-time
• Just-in-time

Available clash mitigation strategies:

• Block new notes
• [new] Stop old notes
• [new] Retune old notes without stopping them

• New: Add ChannelTuner::apply_channel_based_tuning

• Improvement: Include full KBM model in almost every command
• Improvement: Accept explicit scales (file or stdin) in almost every command
• Improvement: The mts and dump commands can be used without pipes
• Improvement: Use YAML instead of JSON

• Improvement: ChannelTuner::apply_octave_based_tuning now accepts any kind of tuning including non-octave-repeating ones
  • Note that non-octave-repeating scales might consume a large number of channels
• Improvement: The tuner module has support for the full KBM model
• Improvement: find_by_pitch has better numerical stability
  • When right in the middle between two scale steps a sharp version of the lower scale step is preferred

• New: Full KBM support for non-linear scales
  • (Scl, Kbm) implements KeyboardMapping<PianoKey>/KeyboardMapping<i32>
  • (Scl, KbmRoot) implements Tuning<PianoKey>/Tuning<i32>, i.e. KbmRoot replaces the old Kbm
• New: KBM files can be parsed and imported
• Change: The ratio module has been merged into the pitch module
  • tune::ratio::Ratio becomes tune::pitch::Ratio

• New: Add StageSpec::String for physical string modeling

• Fix: microwave can now be compiled with the latest Rust version. An upstream dependency was not well maintained.
• Improvement: By removing nannou_audio as an upstream dependency, setting low audio buffer sizes like 64 now actually has an effect and can be used to improve latency times

• Internal: Update midir dependency to 0.7.0 s.t. microwave can update to it as well

• New: Add reverberation effect
• Improvement: Add more LfSources to gain access to properties like velocity and key/channel pressure
  • The new properties enable more flexible waveforms, e.g. a sax waveform whose sound is brighter at higher velocities

• New: Add LfSource::Oscillator
• New: Add 2nd order filters:
  • Low-Pass (replaces the naive resonance filter)
  • High-Pass
  • Band-Pass
  • Notch
  • All-Pass
• Improvement: Better waveforms format
  • Use YAML instead of JSON
  • Some data structures have been flattened for a flatter hierarchy
  • Example: you can now write resonance: 440.0 instead of "resonance": { "Value": 440.0 }
• Improvement: Add from and to parameter to LfSource::Controller
• Improvement: Replace LfSource::Slope by the more flexible LfSource::Time

• New: Add FilterKind::HighPass to modular synthesizer
• New: Add audio-in feature
  • To create a waveform based on audio-in use "AudioIn" as buffer source
• New: Add live interactions to modular synthesizer
  • E.g. you can write "Controller": "Modulation" to gain control over the resonance frequency of a resonance filter via a modulation wheel/lever
• Improvement: Treat the waveform's nominal frequency as a LfSource that can be applied to almost any stage parameter
  • The nominal frequency of a waveform is represented by "WaveformPitch". This means "frequency": 1.0 becomes "frequency": "WaveformPitch"

• New: You can now define your own waveforms!
  • When microwave is run for the first time a file waveforms.json is created
  • Adapt this file to create your own waveforms
  • There is no documentation of the JSON format yet but the parsing error messages will help you to find valid configurations
• Improvement: The root key and reference key can be changed independently

• New: Add new sounds (chiptune, brass-like, distortion)
• New: Add rotary speaker effect for cool organs sounds
  • Ctrl+F10 to enable/disable the rotary speaker effect
  • F10 to accelerate/decelerate the rotating speaker
• New: Send note events to MIDI-out (e.g. FluidSynth)
  • Single Note Tuning messages are used to set the tuning
  • Multiple channels are used to keep the detune per note small
• Improvement: Ctrl+F9 to enable/disable delay effect

• Improvement: Yield two Single Note Tuning messages in mts command in order to retune all 128 notes.

• Improvement: Generify some functions of the math module
• Improvement: Better ergonomics of the Tuning, Scale, Pitched and PitchedNote traits
  • pitch::find_in() has been moved to Pitched::find_in_tuning()
• Improvement: Better mts API
  • Return two Single Note Tuning messages when the number of retuned notes is 128
  • Convert ChannelTunings to SingleNoteTuningMessages
• Improvement: More API documentation

• New: microwave can now send MIDI messages to an external synthesizer instead of using the built-in synthesizers
  • The external synthesizer will be tuned via MTS / Single Note Tuning message

• Internal: Share more code with microwave
