Import scl files

• New: Parse and import scl files
• Improvement:
  • The scl and kbm functions have been moved to a single module named scala
  • The with_key_map has been removed as it was too impractical to use. In return, the ergonomics for (scl, kbm) tuples have been improved.

Bug fix and big bang refactoring

• Fix: Notes getting stuck when changing the root key while playing
• Internal: I did a large refactoring to clean things up. As soon as it compiled, it worked without errors. Thanks, Rust!

Better sound quality, sustain pedal, controllers and delay

This release contains some very cool features:

• New: All channel messages received from a MIDI input source are passed to the soundfont rendering engine. This means, the following MIDI features work:
  • Sustain pedal
  • Pitch bend
  • Aftertouch
  • And more ...
• New: Add delay effect
• Improvement: microwave now uses up to 16 differently tuned Fluidlite channels for sampled playback
  • Pro: The sound quality is as good as if you were using 12-EDO
  • Pro: You can access the full MIDI pitch range

Minor improvements

• Improvement: Add more operations to the Ratio API

MIDI control

• New: You can now play back notes sent from a MIDI device

Porcupine notation

• New: RatioExpression and RatioExpressionVariant providing details about the parsed ratio expression
• Improvement: Add porcupine representation as an alternative to meantone for better note names and keyboard layouts

Porcupine notation

• Improvement: When a porcupine layout exists its properties are printed (edo command)
• Improvement: Fractions are no longer converted to cents when exporting a custom scale

Porcupine layout

• Improvement: When meantone layout is a bad choice, porcupine layout is chosen for fingering. To enforce the usage of porcupine, for example in 22-EDO, provide the --porcupine command line argument.
• Improvement: SF3 support is disabled by default. To re-enable it, use the sf3 feature toggle.

Keyboard layouts

• New: Find meantone-based keyboard layouts for any EDO
• Improvement: Include tuning program in MTS sysex message

EDO analysis

• New: Print step sizes, keyboard layouts and note names for any EDO scale
