After much frustration with the Yamaha MFC10 (mainly thickness on my part…), I was finally able to figure out how to assign MIDI CC numbers to the foot buttons. Using the "learn" mode, I got the Pitchfactor to see the buttons. Works like a charm… The Yamaha is overwhelmingly capable. But having this breakthru is inspiring me to conceptualize more setup possibilities with the MFC and Pitchfactor. Lots of fun and interesting music….
