HERE IS MY PROBLEM WITH MY MORNINGSTAR MC6 PRO:

I think I know how to assign CC#, but each time I assign CC# in the looper of the H90, the looper stops to work.
I press and hold any of the LED buttons (P/A/B) in PERFORM MODE in the 3thrd page where you can fin REC, PLAY and STOP.

I assign for example:

CC50 REC
CC51 PLAY
CC52 STOP
CC53 undo/redo
CC54 ERASE
with the learn function in the H90
but after that, I can not use the looper, even directly with the foot switch of the H90… that’s crazy
