High-pass filter, better modular waveforms, audio-in, live interactions

• 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"

Microwave goes modular!

• 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

Several improvements

• 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

Minor improvement

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

More sounds, rotary speaker effect, MIDI-out

• 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

Better non-monotonic tunings and more tuning messages

• New: Add SortedTuning to treat sorted Scales as Tuning<i32>s
• New: Add tuning program change and tuning bank change messages
• Improvement: Make ChannelTuner accepty any Tuning<K>

Cosmetic/internal improvements

• Internal: Share more code with microwave

MIDI output

• 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

Tuning transformations, Vals

• New: Serialize MIDI messages
• New: Add tuning transformation functions on MIDI messages
• New: Calculate patent vals

Pitch-bend based live retuning

• New: Add monomorphic and polymorphic pitch-bend based live retuning
• Improvement: Analyze any equal-step tuning
• Improvement: Print patent vals of equal-step tunings
