Thanks. I've looked at the midi transform tool in muse... it does *some*
of the things I want. Perhaps I should look at adding some sort of
scripting to muse to do the rest. It would be nice to make use of an
existing framework and to be able to do things inside an existing editor
rather than doing the "save to midi file, run some program, reload the
midi file" thing.

Good point. I'll have to have a look through the muse code.

Audacity can send audio data to nyquist and nyquist can handle both
audio and midi data, so I guess hacking on audacity is another
possibility. Audacity loads and displays midi data but doesn't play it
or (AFAIK) pass it to nyquist yet.
I guess I'm looking for a scriptable midi editor similar to the way in
which, say, "snd" is a scriptable audio editor.
Thanks for the comments Philip.
BTW, I noticed your comment in another thread about having a guitar midi
controller. Which controller do you have? Does it track well enough to
be useful? I'd love to get into midi guitar, but I'm not sure where the
current state of hardware/software pitch tracking is. Any comments you
have would be useful.
