hi, i just purchased the blueboard, and am using it with MainStage 3. I want to know, is there any way i can map the "A" button with "previous patch", and the "B" button with "next patch"?? i just want to simply move to the next patch... but it seems i need to memorise the bank and program number for each patch, and press 3 seconds for the next bank and something like this...?? i hope it's only i don't know how to set up....or else it's really dumb!!!
