That's what I'm trying to do with midifile. It just outputs each MIDI 
packet as a list from one outlet, with the current tick number on 
another. (It doesn't parse the MIDI since that can be done externally 
with [route].) It should be easy to pack those into a qlist and later 
edit the qlist, then play it back into a midifile to save it in .mid 
format. If the writer part only writes type0 files it can be quite 
simple, since there is only one track (and I will have time any day now 
to actually write it...type1 needs preallocation of unknown amounts of 
memory). Another object could always be made that generates type1 
(multitrack) from type0 files.
