Hi,
I am using an APC40 MKII. I had set a MIDI map earlier this week, that used 1/A#3 through 1/C#4 (attached is a picture of the buttons I am referring to) to change through decks. But now, those buttons instead change my device's MIDI channel and it has completely messed up my MIDI knob layout. THIS ISSUE HAPPENED AS I WAS PERFORMING ON THE DEVICE, AND WILL NOT CHANGE BACK.
Please look into this bug, I want these buttons to go back to being just buttons without changing the entire layout of my APC.
