 Code in MusE does some of these things. The user interface for doing them

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.

 The second part is harder, where you talk about the "music view" in
notes,
...
  beats, bars vs the data view. MusE stores noteons as
offsets. Of course in
...
  the program is the logic to relate the note event
offsets so the track
 editor, but I have not seen that this is exposed in an api. 
Good point. I'll have to have a look through the muse code.

  Thinking about it I wondered if the code could be
extended to allow you to
...
  send note data from the track editor to an outside
program. For example,
...
  if you could send the data to jmax that did understand
midi, but provides

  interesting ways to manipulate the data. Being able to
do it at run time
...
  is another idea I suppose, with connections like the
way ardour can send
...
  audio to effects or outputs. 
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.

Cheers,

Stuart
