mdcmp

mdcmp (MIDI Composer) is a Python library for easily generating songs and emitting MIDI files.

This is a work in progress.

• MDC file format spec
• Progressions spec
• Grid

TODO

• Load MDC file: Convert mdc file back to grid

• Composition:

  • Create the Composition class.
  • Build a mdc bank of canned beats and progressions.
  • Load banks, glob style.
  • Generate random song from selected progressions.
  • Generate intros, verses, bridges, breakdown, chorus, outro.
  • Fade tracks out.
  • Fade tracks in.
  • Humanize: Add some velocity and timing micro-shifts.
  • Drums: Fills.

• CLI:

  • Convert: translate mdc files to midi files via CLI.
  • Compose from cli by specifying layers, loops, and params to composition object.
  • Example idea of CLI composer usage:

mdc-compose \
    --load samples/lofi/ \
    --out name.midi \
    --loop-all 2 \
    --layer intro=drums1:lofi2,verse=drums1:lofi3  \
    --loop-layer-order intro:2,verse:10,intro:2,verse:10 \
    --velocity-jitter 13 \
    --fade-in 10 --fade-out 10 \
    --auto-dynamics [0-10] \
    --humanize
