BMC21. Full Wave Dual Rectifier
This is an all analog synthesizer module used to alter the timbre and create new harmonic content. It consists of two identical full-wave rectification circuits, which can be used seperately or one cascading into the other. Each circuit has a manual bias offset as well as external CV that can be used to offset the bias.
The board features PC mounted pots for less wiring, and mounting holes for flexibility in panel layout. There are Eurorack and MOTM power connecters.

modulating their bias.
Here is an MP3 demo of two rectifiers run in series with VCOs modulating their bias, the VCO's are synced to the oscillator on the input's frequency and are having their inputs modulated by LFOs.
Here is a youtube demo of the module.
