Analog Synthasizer Designs

These are designs for EuroRack compatable synthasizer modules.

Each module is designed as a seperate project in KiCAD Each folder includes a BOM from Mouser.com, the Gerber Files if you just want to have a board printed and a PDF of the schematic.

I have taken insparation from all over the web including Music From Outer Space, Yusynth and Look Mom no Computer. Some designs are outright copies of their schematic with my board layout design.

Look in Overal Design.xlsx for where I have gotten the design from And current progress on the designs.

All designs are without waranty, please build at your own risk, I have not tested any of these designs at this time. If you build any of them, you assume responsibiltiy for any potential damage to your existing equipment.

Questions

How big is the Patch Bay PCB?

It measures 25 × 100 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Patch Bay use?

9 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Patch Bay KiCad files?

From the BruteClaw/Analog-Synth repository on GitHub, at the commit this page was made from: the board is Through Hole Designs/Patch_Bay/Patch_Bay.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Patch Bay design in my own project?

Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
