Demix By Note.
You can then create new duplicate tracks from the "de-mixed" tracks(the +sign with the little square with lines in it) and then "copy" the demixed tracks and "paste at original location" to those new tracks. Then delete or mute the original track(s). (The original "de-mixed" tracks are not actually independant. If you mute or solo any track, they all mute or solo, for example)
The usual response from experienced people is to use a multi-out instance of the instrument(EXS24 or Ultrabeat) though...
Thank you, yes, I tried both of those approaches. However, as I recall they do not result in a set of tracks that allow me to independently punch in say a new fill on the snare for example. The demixed tracks or their duplicates do not seem to accept input. It has been suggested that a separate MIDI channel for each drum would help; however, my old OctaPad transmits on one MIDI channel only. If I was playing one drum at a time I would simply make a track for kick, one for snare, etc. But to play the entire kit at once onto separate tracks has me stymied. Could I play 9 EXSs at once, each recording to one track and each with all instruments but one deselected?
