MEC question. apologies, posted in wrong category earlier

Hello, this is a long shot.

I noticed that there doesn;t seem to be a way to differentiate the main keys from the four outer keys. I wanted the four keys in oder to control octave, scale etc but the transmit the same key numbers as the main instrument keys. If the pico script is set to 48 as first note, the four outer keys produce 48, 49, 50, 51

Im probably missing the obvious. Has anyone managed to make these different of seperate them?

many thanks for any pointers

(i havent upgraded to the new MEC update yet)
