Do you know for sure that the soft synth you're driving actually supports CC11? Not all do. CC11 is not strictly defined in the MIDI spec, so implementations vary.
Thanks for the response! The MOTIF XS-7 simply costs too much to not support CC-11 plus I've done it before in previous versions. Although I can't just draw an expression envelope in track view and expect it to work like volume does, I
can draw one in Piano Roll and then convert it to a track envelope after which it works and responds to node manipulations as expected. It's a work around but it'll do since Expresssion envelopes allow you to tweak track volume without re-drawing all the crescendos and diminuendos. Hope this helps someone else.
