Brad, I'm using 2 (or 3) keyboards at a live gig and want to centralize all the controls, so the iPad app is a great solution. Choppin, For program changes I set the PX5 to use channel 5, (this works.). My Hammond already uses channel 1,2 and 3. Would CC's (like 07,11) need to go to different channels to make changes on the casio? ----- UPDATE - I did test this and sure enough, sending cc07 to channels 1-4 works, even though the keyboard is setup to receive on channel 5. Having a hard time understanding why that is. Any ideas? --- Thanks, mikeG
