My ETC shows up later today. I got pygame running yesterday ... so here is my first stab at getting some basic sprites rolling.
NO AUDIO - sorry .... just a proof of concept.
Without even having the ETC in front of me ... I'm thinking:
Knob 1 = rotation
Knob 2 = x direction
Knob 3 = y direction
Knob 4 = color (with full clockwise being rainbow flow, and full counterclockwise being original sprite color)
Trigger mode will make the sprite jump/scale.
