I'm not sure what I'm missing here. I set preset D as follows:
action: press type: pc scroll up
slot: 1 lower limit: 0 upper limit: 10 midi channel: 1 increment: yes
Looking at the midi monitor, every time I press the D switch, it sends PC 0. It seems like increment isn't working. What am I missing here?
What firmware release are you on. Prior to 20191105_MC6_v3_4_2_Beta.hex there was a known bug. Upgrade and see if it works.
