Building the WTPA into a MIDI controller keyboard

edited August 2009 in WTPA1 Mods
I have an idea to buy a cheap 2 octave MIDI controler and mount a WTPA inside and have a nifty portable keyboard version of the WTPA. You could route the controller MIDI out to the WTPA MIDI IN and go from there. Then you could assign the controller's knobs/sliders/buttons to the WTPA functions. The question is, what functions can the WTPA be controlled with over MIDI? And is it possible to code more MIDI control for various things? This, of course, is me dreaming again, even before I get my WTPA, hah!!

Cheers, graham


  • you can control more with midi than you can from the front panel..
