Drop a .mid file or an audio file (mp3/wav/flac) to begin — Midio performs it himself.
Drop several audio stems at once (bass.wav, piano.wav, lead.wav…) and their names decide who dances what.
Sit back and watch the show — every jump, combo, and biome is generated live from the music.
Or drop .sf2/.zip files into the soundfonts/ folder next to index.html — they load automatically, no clicking required.
You can drop a different MIDI/audio file mid-song. Press ` for debug, T tracks, F SoundFonts, fullscreen button for immersive play.
