****ing great idea
I reckon there's a market out there too
I know I would buy one for sure.
If you got D16 or ABL on board with some help in the programming side
you could have a purpose built 303 controller
that links automatically to the plug in through your host ( ableton , cubase )
and can be used as a general midi controller too
jesus why am I saying this ???
time to patent the idea
and quick!
