Hi. I'm new at changing codes etc. I want to build a midi floorboard with only 4 or 5 buttons. 1,2,3,4 and 5. I also would need bank up and down. I've seen the old floorboard here on this site, and I think I can use that with some adjustments to the programcode?? However...I don't know how to do that. Any suggestions? //mr.P
