The classic circuit bent Speak & Math with a custom touch pad. The original buttons are superimposed in blue over the fractal graphic, but it's hard to see them in the photo.
Mods include: pitch up/down knob, pulsing blue LED under display, (2) three position glitch switches (on/off/on), pitch activate switch, short loop, long loop, capacitor warble effect and a loop release button on the side of the case. I especially like the loop release button which is great when searching for interesting sounds. You just put a normally closed pushbutton switch in series with the loop switch.
Audio Samples: Stereo effect added
