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 : 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
