From the project

Fully analog DIY-friendly modular synth

Combined analog bitcrusher, LFO and an output interface with overdrive in a single Eurorack compatible module.

‼️ IF YOU ARE NOT BUILDING FROM THE LATEST PCB REVISION IN THIS REPOSITORY, PLEASE CHECK THE FIX LOG (PCB ERRATA) BEFORE STARTING, AS EARLIER REVISIONS MAY CONTAIN ISSUES THAT REQUIRE CORRECTION.

- Analog bitcrusher - External trigger of analog bitcrusher, which allows sample & hold usage - Analog LFO with square and triangle output - LFO works from about 0.1Hz to 200Hz audio range - LED indicator for LFO - Output module to interface line level audio - LED based overdrive in output…
