To link the digital signal processing on a laptop or Raspberry Pi to the analog synthesizer, I have made two usb-to-cvgate converters. The first one I designed and implemented was a one-channel version that is able to output up to (approximately) 5 Volt. The second one is an improved version with four channels that can be controlled from 0 to 10 Volt.
Using the EAGLE PCB design software, I have drawn the schematics which should allow others to copy them. Also included below is the bill of materials (BOM) with links to component vendors. I have mainly been shopping on eBay, you can also get it elsewhere of course.
Details of the one-channel USB-to-CV/Gate converter can be found here on our Github page.
Details of the four-channel USB-to-CV/Gate converter can be found here on our Github page.

Hi,
Very nice project! I’m interested in making a 4 ch gate converter.
The schematics and BOM links seem to be broken (they just take me to the front page)
Could you please re-upload them?
Thank you!
Hi Frédérik,
Thanks for mentioning this, I have fixed the links. The hardware details are now on our github page. Regarding the 4-ch version please note the issue at https://github.com/eegsynth/eegsynth/issues/123
best,
Robert
I have just fixed the errors in the PDF schematics and uploaded the correct one to github. See also https://github.com/eegsynth/eegsynth/issues/123#issuecomment-370150194
