And it's done! Old Thomson wireless router fitted with an arduino duemilanove inside, 8 leds on digital out pins, one potentiometer and a footswitch on analog inputs. The footswitch is an old Zoom expression pedal and it has a 100k pot inside it. The midi out port sends midi control change message. The control function is selected with the "select" pot and the value is adjusted with the footpedal. I can send any midi message from this however, so I could turn this into a midi sequencer of sorts, just send midi notes instead of control change messages.
I can choose an effects mode with the toggle switch, which will modulate the control change parameter in different ways. So far I have a random mode, ramp and up-down modes, demonstrated in [http://www.youtube.com/watch?v=z5XRaIapBGM this youtube video] (or [http://vimeo.com/20298364 the same video on vimeo]).
The red freeze button allows me to lock the pedal once I've found a sweet spot. Pretty kick ass for my first Arduino projects! If anybody is intrested in source code or schematics, leave comments below.
Arduino midi out is really easy, [http://arduino.cc/en/Tutorial/Midi check out this tutorial].
