I want to export my multi-track compositions in Ableton to MIDI to make them usable in Sibelius and to make them less susceptible to "ageing out" (what with proprietary project formats and all that annoying jazz). I can't seem to find an easy way of turning .als files into a batch of .midis or anything similar. Any ideas?
You can export one track to MIDI, but it's way, way, too cumbersome to manually flatten all of my tracks into one and then export that; not least because you can't have unison notes without destroying information in one of the tracks.
I don't care about preserving any timbre/instrument information whatsoever - let's pretend that it's just raw note information completely abstracted from implementation and production (but if we can keep that, too, all the merrier).
