Thank you so much for the replies guys.
@nnnnnn yeah I think I was doing this or at least trying (using C4s own button) but somehow ended up failing - which is likely due to my own limitation. The pedalboard config was posted here and I see it was well feasible!
Show me your compact pedalboard setup
@sunbeast you are right, I was using device mode (simply, the one from YouTube video from DMC on hooking C4 up). I'm not tech savvy and it's taking the toll now haha.
Both you and @Gibs210 suggest midi baby 3. So if I program the midi messages for each button to have 1. on or off 2. On&page up 3. On&page down (I am positive it will have to be with help of forums but that's another story...) I will be able to make it for my use case? I will be able to select my desired preset before the song (buttons 2 and 3), turn it off with button 1 and kick it on when needed with button 1. Just asking as I'm afraid I will shell out $$$ to no avail.
