Hi Douglas, Thanks for getting back so quickly.
Yes, I am getting notes out the dlssynth using the same code/the same *dlsUnit. I am using the dereferenced *dlsSynth because I created an objective c wrapper for managing multiple outputs and I wanted to pass in the reference from my audiocontroller class.
I'm pasting here the relevant parts of in this wrapper class -- Note-On and Note-Off, as well as PGM out work. But CC and pitch bend do not. The data all comes from a 3d sensing device, and it appropriately converted into the correct ranges -- all of the data works correctly over "virtual" MIDI to FM8 in ableton.
I'm on 10.8.3
Thanks!
