Today's arduino code changes include adding support for the left hand pot. This now sets the amount of randomness. Fully CCW = none (steady CV out). Fully CW = totally random. The Right green LED now indicates when double-clocking (2x tempo) randomly occurs. The picture below shows the output resulting from this knob being turned from zero to full over the course of the screen sweep.
Processing code changes include a test to represent the incoming data with a circular rather than linear sweep. It's not particularly inspiring and was only tried in the spirit of "let's see what happens"
