An easy (?) way to type jianpu (numbered musical notation) on your word processor. Not very polished and doesn't have sharps, flats and other embellishments (yet), but gets the job done in a pinch?
Not very intuitive to guess which keys map where (except maybe 0 and 1-7) - look at the key maps.
This is a cloneAs per winty5's comment, this is an actual font for converting between MIDI and text; fa Musica is only meant to be keyboard-friendly.
If somebody wants to comment a code for a part of a song, feel free! :)
