if you don't have the track selected which the clip is on, live doesn't read the cc change.
kinda sux. the workaround is to map the same cc to switch to the track that has the clip on it.
ooh
just figured out that it's way deeper than that. you can only assign clip pitching to one cc at a time-so you can drop all clips in pitch with the same controller, but only one at a time, when their track is highlit. wtf.
my question is: "bug or feature"?
