Reply To: Cheap DIY Midi Controller

ok people. cleanest codeset yet. 

Incluses a spot for an expression pedal (or multiples) as well as a VOLUME BOOST with an LED toggling it’s state. This might break with a Preset switch, but will reset if you hit it a couple times.

Lets see if I can get it to paste correctly. If not, download here:
