Every source, plainly stated.
Chromatic includes 53 MIDI editions from the Mutopia Project: 36 public-domain editions and 17 Creative Commons editions. The application code and interface remain separate from these third-party works.
How the music is used
The original MIDI files are stored locally and served as received from Mutopia. During playback, Chromatic may select a melody track, fill long rests from another track, move out-of-range notes by octaves, transpose at the user’s request, and map the result to 16-hole chromatic harmonica tablature.
Tabs generated from Creative Commons material are offered under the same licence shown for their source edition. Public-domain tabs are identified as such. A user-uploaded MIDI is processed in the browser; the user remains responsible for rights in anything they upload or share.
No contributor or source organisation endorses Chromatic.

Harmonica samples
FluidR3_GM SoundFont
Harmonica samples are derived from the FluidR3_GM SoundFont by Frank Wen and contributors, distributed in pre-rendered form by the MIDI.js Soundfonts project. Chromatic trimmed and encoded the samples as MP3; pitch shifting, filtering and breath processing occur at runtime.
