re: Open MIDI File - type 0 extract channels to tracks....

If all tracks are set to audio (as they are now as a default), then that command cannot find any MIDI tracks to work with.

If you set Prefs- Inital Track Type - to MIDI, the extract channels to tracks should work fine.
(After setting the track type - MIDI, do a File-New before tring the command, so that tracks will be MIDI)

We'll correct that in the future, but if you plan on lots of work with MIDI files, and using commands that depend on making other MIDI tracks, it would likely be best to make that setting as Prefs- Inital Track Type - to MIDI


Have Fun!
