Field notes
The homepage describes a palette spanning notes, intervals, scales, modes, chords, and progressions, with outputs that can feed into other nodes. Playback and notation are presented together, including time-highlighted tablature, standard notation, piano roll, and chord diagrams. MIDI workflows include splitting files into tracks and changing their timing or pitch before export; saved projects and group sharing are tied to requested accounts.
