This is an all analog synthesizer module used to make percussive pitched sounds.

The board features PC mounted pots for less wiring, and mounting holes for flexibility in panel layout. There are Eurorack and MOTM power connecters.

Listen here for an MP3 Demo of the module. I'm just sorta turning knobs in this. I have the output of the module patched into the Frequency CV and towards the end there is some self FM.

Here is a youtube video that shows the basic controls of the module.

and here is a demo made by a builder
