Snapshot select with m-vave chocolate pro footswitch

Hello. Can someone help me further with the M-vave Chocolate Pro (via USB) in Modep? The footswitch is recognized as SINCO CTL. With the MIDI display plugin in Modep, I see that the MIDI messages are coming into Modep. I have taken a few snapshots, but they do not respond to the changing MIDI messages. I tested with PC0 to PC3 and with CC channels 0, 32, and 69 with values ​​0 to 3. However, there is no snapshot change. Does anyone have experience with this?
