From the project

modular analog synthesizer for a.p.

Small 6 stage optical phase shifter PCB, designed to plug into a larger motherboard.

The main circuit is based on the famous Mutron phasor circuit with the addition of voltage controlled feedback. This PCB includes the audio path and CV inputs for frequency and feedback, but does not include any modulation sources.

The intended use for this board is to plug in to a larger motherboard which contains slots for two of these phasor boards, as well as modulation sources, panel controls, and input/output routing. This motherboard could accept different filter boards sharing this footprint and…
