- 01-basic-chord.py: chord progressions (C major) - 02-90s-dance-track.py: 5-track 90s dance (arp, bass, pads, drums, piano) - 03-arpeggiator.py: reusable arpeggio generator with dir/type options - 04-single-note.py: minimal single-note example - Rewrite compose_neon_dreams.py: cleaner track functions, proper velocity=0 note_off, tick helper - Add README.md with setup and API reference Uses MIDIUtil library (beats-based API) instead of mido (clocks-based API)
MIDI Util Examples
Working examples created from the MIDIUtil source repo patterns. All examples use MIDIUtil with beats-based (not ticks-based) time, the cleanest API for MIDI composition.
Setup
pip3 install --break-system-packages MIDIUtil
sudo apt-get install -y fluidsynth fluid-soundfont-gm
