hallo,
I finished to populate the cgs48 VCO... but I am quite disoriented about knobs and switchcraft.
How I have to connect them, I mean... there is a wiring diagram??

Thank you

Hi Lorenzo
possibly Ken hasn't posted a wiring diagram because there are so many options with this VCO. You can have it as minimal as 1 CV jack, a coarse tune pot and a tri-out jack.
Or the full show with sub-oscillator, PWM, sine shapers, FM inputs, etc.

If you want to give some desciption of what features you want, or post your panel design, I will try to draw a connection diagram for you.
Very Happy

Hi
I populated this pcb ... and it is disconnecteed since last winter Embarassed

I don't know... If you are so kind to draw a diagram ,maybe I will start and then understand how to go on...
so 1 cv is enougt to undestrand so 1V/O input... tune pot, fine (?), common outs, sub-oscillator, sinc, sub-sync, PWM, SCW... I think it is enought, don't you?

... I will pay you a beer! Wink

Just focus on the 2 modules to the left!

There is 2 options. One with everything included. And one that is a slimmed down version.

@zthee, thanks for sharing! I wonder why you use a bi-polar swashes for VC Divide and VC Shape. I thought them simple attentuators. Am I wrong?

They are just attenuator on the original design. I used a small PCB that I attached to the pot which gave me inverting capabilities.. So - the instructions and the picture doesn't really match 100%.. Sorry about that!
