@Zealot:
This SK1 is totally modular. There are no pre set mods. 
The white patch points in the middle of the faceplate are connected to the audio synth chip. All of the switches and potentiometers on the faceplate are for patching and controlling points from the main patchbay. The BIG potentiometers are 10 turn pots. These allow you to make very fine adjustments.
