Overview
Vco is an open-source printed circuit board by Micosilent, from the Micosilent/MFOSmod repository on GitHub. It is a 2-layer board of 50 × 100 mm with 103 parts on 82 nets, routed with 953 tracks and 65 vias.
It is built around the TL072 and LM13700M. Its parts include 48 resistors, 15 capacitors, 11 connectors, 8 diodes and 7 ICs.
Main components
2README
README.mdMFOSmod
This is a collection of modules from Ray Wilson's Music From Outer Space.
I will be using SMT in all the places I can, and replacing obsolete components that cant be found in the usual electronic distributors ( mouser or digikey ), with appropiate ones, following if possible Ray Wilson's advice on parts.
MFOS SUPER-Modular Bundle
The idea is to end with all the modules from the supermodular bundle for starters, once we have all this modules we can look into transcripting other modules.
TODO:
- 1. VCO
- 2. State Variable 12dB/Oct VCF
- 3. ADSR Envelope Generator
- 4. Mini-Controller
- 5. Dual Log/lin VCA
- 6. VC Low Frequency Oscillator
- 7. Dual AR Envelope Generator
- 8. Noise Cornucopia
- 9. Four Channel Stereo Panning Mixer
- 10. Delayed Modulation Module
- 11. Sample & Hold
- 12. Sonic Multiplier
- 13. Low Pass 24db/OCT VCF
- 14. Wave Freaker
- 15. Stereo Auto-Panner
- 16. Multi-Function Module
- 17. MFOS 8 Stage Phase Shifter
- 18. MFOS Voltage Quantizer
You dont really need all this modules to make a working synthesizer, but I am planning to make all the modules in KiCAD and start bulding them progresivly.

Questions
How big is the Vco PCB?
It measures 50 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Vco use?
103 parts, built around the TL072 and LM13700M. 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 Vco KiCad files?
From the Micosilent/MFOSmod repository on GitHub, at the commit this page was made from: the board is VCO/vco.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Vco design in my own project?
Its repository states no licence, so its author keeps all rights: ask Micosilent before reusing the design.
