Ciao, I need your experience to go ahead on midi designs !

I would like to build a pedal board in order to send midi program change to various midi gear

I only need 30 program changes and 30 buttons

If I use midibox core with pic 16f877 [http://ucapps.de/mbhp\_core.html](http://ucapps.de/mbhp_core.html) and a din module [http://ucapps.de/mbhp\_din.html](http://ucapps.de/mbhp_din.html) with this software [http://ucapps.de/midio128/midio128\_v1006.hex.zip](http://ucapps.de/midio128/midio128_v1006.hex.zip) will I also send a program change through midi out when I will press one the 30 buttons ?

Please let me know,

thanks,

Domenico
