Hi, thanks for all the tips here! Unfortunately I can't find a solution for this, yet! In a live set up, I want to use the px5s as a controller for a nord stage compact (1st gen), which is also used as the midi input for sampletank and other synths on iPad, via steinberg ur242 interface. I am also reading charts on iPad in unrealbook (great app!) and have set program change messages to go to the nord and the iPad synths. So the connections are: midi out of the ur242 into px5s, then out of px5s into nord, then out of nord back into ur242/iPad. I can set the midi output of the px5s to 'keys' or 'midi in' but can't see a way to include the program change messages that the px5s is receiving from iPad and pass them on to the nord, along with notes played on Casio. Is there a way around this? Or do I need another box of some kind!? Thanks in advance! Matt
