Thanks for the feedback.  Those are certainly some good ideas.  Believe it or not we have made some sketches for a possible new screen in H9 Control called Combinations that would allow H9 Control to act like a command center.  We were more focused on making all Eventide products work seamlessly together but had thought that it would be nice to have the ability to control other MIDI device via program changes.  I'll mark you down as a +1 for that.
