comparison base/RealTime.h @ 26:090c22aa726a
* Add the Note layer for pianoroll-type display of note-type data
* Complete the MIDI file importer (well, nearly -- it would be nice to
be able to import the non-note data as other sorts of models, and that's
not done yet).
* Minor refactoring in RealTime etc
