[sdiy] presets on a modular

The idea I had was that each module still retained its knobs and stuff.
Each jack socket was replaced by a switch with an LED. and that the main
controller (MCU) had an LCD on, which would you could 'look' at each modules
settings for that patch, and the either modify it on the LCD, or on the
module itself.
The touch screen is a nice idea though.

Sounds very similar to the way I was going :-)

I had also though of including a mouse input and VGA screen output on the
MCU for clearer visability of the 'patch'.
