README
README.mdAnalog monosynth with digital control path
The idea:
- A stripped down version of the Josh Oxford Ribbon Synth with some changes
- No integrated ribbon controller
- MIDI and CV inputs
Status:
- 1st prototype is built and under evaluation
- All major features work
- There are a few PCB kludges required for the first board revisions
- Expect minor componenent and code changes as evalutation continues
- The jack panel and body are not started yet
- Documentation is incomplete while the design is in flux, expect some dead links to schematics/etc for now

Questions
How big is the Main VCO board PCB?
It measures 133.9 × 165.1 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Main VCO board use?
295 parts, built around the TL072, LM324, NE5532 and LM4040C25FTA. 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 Main VCO board KiCad files?
From the JordanAceto/micro_ox repository on GitHub, at the commit this page was made from: the board is circuit_boards/main_VCO_board/kicad_7/main_VCO_board.kicad_pcb and its schematic circuit_boards/VCF_VCA_board/kicad_7/VCA.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Main VCO board design in my own project?
Its repository publishes it under the CC-BY-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
