the number doesnt change im afraid, the easiest way to do it is like this. if you have got the ainx4 boards hooked up to the core, each ain will take 8 pots/faders
the board allows for 4x8 pots or faders, so if the pot you want is on the second set of pins then thats 9-16 so if you wanted pot 9 to assign a midi cc# to you would move the pot number to 9 in the Editor and so on, if you do all the changes first, then make sure learn is turned off in the editor then do a sysex dump to your mb64
yes you have to manually change the pot number in the editor when you change the number you move up one pot, all you do is edit the pot to the cc# you want then go to the next one and so on. when you have done this you then do the sysex dump to the core.
