Regardless if I use the Pro2 over USB or midi, i can't change patches on the pro2 when local is off
It changes the number, but not the patch name or sound. This works fine when using the Pro2 to control other synths.
So it seems that the patch change message is sent in local off (as it can be recieved by other synths) but not accepted on the way back in. While a correct midi loop is in place.
When the Pro2 is in local off, I can only do patch changes via an external sequencer.
I consider this a BUG.
