In response to some other interest in Steiner synthesizer gear, specifically the Microcon, I've added some clarification to the Microcon page regarding the DAMP switch and wiring. Please visit http://analoguerealities.com/projects/steiner-microcon/ for the details. Nothing too dramatic but I think there has been some confusion on this switch. Nyle found an error on the schematic regarding the wiring of the DAMP switch which was built into the Rev 1.2 PCBs. The fix is just swapping a couple of the wires on one side of the switch. The Rev 1.3 PCBs corrected this error and can be built as shown in the 1.3 schematic. I hope this helps.
