The main issue as I see it is when you have the audio in DB, and for arguments sake, you want to listen to bars 78 to 82 to see what is needed. The audio would need to sync here. One for Ben's magic I guess : - )
I wonder if Ben might not have more important things to do for us. Isn't combining various tracks from various sources--e.g. audio with MIDI, or with DB--what the bigtime sequencing programs like GB, Reason, Live, etc. are all about?
Rather than clutter up a great percussion-composing program with extras that don't really do the whole job anyhow, wouldn't it make more sense to let one of the big boys do the synchronizing, and just switch back and forth between the sequencer and DB when needed to tweak the drum parts?
