first of all: hi everybody and thanks for site , project and everything. I build the "old" floorboard ( http://www.ucapps.de/floorboard.html )and it worked right-out-the-box , first power-on :) I will package it VERY small , so small to stick-it outside a guitar ( or , if i find a no-vintage strat ,i will build INSIDE, I'll post pictures, of course ! ;) ) I would like to make a litlle mod: the program-change button marked "0" it would be better to become the "10" button for some midi hardware so for every banks to have from 1 to 10 and NOT from 0 to 9; is it possible ? I got a look inside the source code and I think I have to modify the "button.inc" file, but I'm not an expert in PIC code :-[ ..( ..not yet , i hope to be in future.. ). Anyway , thanks again everybody for the knowledge and the good quality projects I found here around.
