The Processor is the section at the top of the VCO schematic. It looks
as tho the Elby panel allows for just one CV Processor pot.
wire the CV1 jack to the centre pin of the CV1 pot. The outer pins go
to PCCW and PCW on the PCB. This is quite different from the norm but
an excellent feature of this VCO.
The FM AC&DC and PWM pots are all connected to their respective jacks,
wire to an outer tab, the other outer tab/pin of the pot goes o
ground. The centre tab is connected to the PCB.

Sub Cv jack to outer pin of Sub CV pot, centre pin to CVS on PCB,
other outer pin to ground.

in series, same as for the SUB CV, wire the centre pin to SHAPE CV



This is my interpretation of the ELby panel - i haven't actually used
this panel. Best check with Laurie if you are not sure.
