Totoro is a portable, analog synth made on top of MCP6004 opamp. It features 2 VCOs (one could act as LFO) and simple VCF. Here it is a short video demo.
This open-source project based on original design of SyntherJack's Totoro and published with his permission.
In v1.0.1:
- Some of the components were rearranged
- Batteries moved on top side of PCB so overall assembly is almost 2 times thinner now
- Minor layout issues were fixed.
