Thanks! That works, although it creates 16 channels even if there is only data in 1 channel. It looks from the docs like I can might be able to use filters to solve this.

Holy crap, I'd never heard of midish, but it looks like it'll do all kinds of stuff I was going to write PD or Python (rtmidi) code to do, i.e filtering, splitting, mapping, etc.

Nice, a MIDI shell that I can run from inside emacs. Very useful.

I *love* this linux-audio list. Thank you all so much for being around, and being so helpful.
