Hi Lawrence, I bought an MS-70cdr and watching some videos on youtube on how to control it externally I found your video and I was very interested in carrying out this project. I made a simple MIDI controller with arduino UNO for Line6 M5 with 4 buttons and it works perfectly, and now I want to build a controller of the one you built for my MS-70cdr pedal. I have some doubts... 1. Does the MS70cdr pedal automatically recognize the foot controller when plugging the USB cable? 2. Does your code accept to connect 2 DPDT switches to UP and DOWN of banks? or would it need to change it ?? 3. Do you have a list of material or some step by step wire connections on Arduino? 4. Could you send the code to my email so I can make my USB foot controller?
Sorry for the doubts, but I need to know to start the project.
