Just one question; it looks like these could be mounted sandwich style parallel to the front panel, but I don't see any holes for standoffs on the boards. Any easy way to do this?

The VCO PCB measures only 78mm x 98mm, so there is plenty of room to add 10mm to two sides should you wish, assuming, like me you are mounting onto a 21HP panel. I guess you'd then have to design your panel to include space for standoffs too. Not keen to do this myself.

Maybe I am blind, but looking at his layout I didn't see that. Maybe it just isn't referenced on there? Any chance you could do a screen capture and just highlight the area where this action happens?

Sorry to be a broken record about this feature, I just think it adds a lot of value to the VCO and I am not understanding how to implement it.

If im not wrong, its the empty pad just between the VCO Scale and VCO Freq trimmers. There is a 270k Resistor connected to it.

Andy's layout shows two of the pads jumpered for permanent non-LFO operation. Remove the jumper and connect the three blue pads to an SPDT toggle. This cuts keyboard CV in to the VCO and references it to -ve via the 270K resistor. Alternatively, connect the lower blue pad to the normalised lug of the CV input socket - saves a switch.
