Rusty, what is the actual sound generating device for your MIDI tracks in RB? Is it an external sound module/hardware synthesizer?

If so, then you need to make sure that ProTools is sending MIDI data to RB.

If it were me, I would do the conversion from MIDI to .wav in RB so that all you are dealing with in ProTools is audio data.

If you are getting some kind of sound in RB from MIDI tracks, you are either converting from MIDI to audio inside the computer or outside the computer. As soon as you have that figured out, you are one step closer to getting this done. Until you have that key part of the puzzle figured out, don't even bother with ProTools.
