First of all, I know a couple of you PMed me (at least two). sorry about the delay, for some reason my PMs dissapeared when I came back several days later and I forgot who it was.
Anyways, my first attempt at AVR programming! (cope-pasted from my blog) Hold down the "record" pushbutton, "draw" out an LFO/envilope shape with the "shape" knob (it can be several seconds long), and release the button for it to start looping the shape and modulate the volume of whatever instrument you have plugged through it. AKA "tremolo". Push button again to design a new one. [U]Or[/U]! Or toggle "punch-in" switch to edit the existing shape with whatever you feel! "smotheness" knob makes it smooth if the waveshape sampling feels a bit too steppy/aliased. It happens if you sample at a very slow tempo and keep it very slow. "speed" accelerates or decelerates the LFO. I forget what "volume" does.
Two LEDs on either side of the bypass switch (under the decals/finish). The one on the right follows your wave "drawing" as well as when it's looping. "firmware upgradeable"
