Thanx for your precious help! Although the result seems very satisfying I m sure it can be tweaked again by really qualified people, I ll tell you if I see collateral damages using syncro Smile

Hey guys,

I would like to include some other waveshapes besides the default Pulse & saw.

Which one would you guys consider ?

thx

Hello! I've not tried myself to add waveforms, but maybe you can find some great infos on Bill & Will's page, if you haven't seen it before..

There is a schematic for adding triangle and sine outputs on page 12 of this thread and a stripboard layout for that on page 17.

Take care,
Doug

I added that circuit (thanks Peasant!) and it works really well, couldn't imagine the VCO's without the other waves!

Hi,

I am also about to finish the great sounding Living VCOs and I would like to add that Hard Sync feature.

My knowledge level is limited, but I am trying to improve day by day.
Here is my drawing... it would be great if anybody can confirm:

Hello Marc!
I don't have an original PCB made by the great Jurgen himself so I can't check myself if everything is correct, but it looks like there is a mistake where I ve put a red cross :

This part of the additional circuit should be connected on R20 resistor as you can see here (not on IC3's pin2) :

Any news about the availability of PCBs for this project? I'm very eager to build one.

Nope, the existing PCB's can't be sold due to legal issues that are still unsolved.
