Thank you, again, for taking the time to explain.
One thing though: I believe I interpreted it the wrong way when you said "1:- Master mode on the Yamaha let's you do this. On the FA, you can send midi data but cannot specify the patch number/bank. If you use studio set #10, it sends midi patch change #10."
So can the FA, within a studio set, tell external gear to change to a specific patch? (e.g. have a King Korg which does the VA duties in my setup so if I had my own setup for a song can the FA communicate to KK to change to the patch I require for that song?)
