Penrose

Quantiser

Penrose

Overview

Penrose is a simple CV quantizer DIY kit for the eurorack format. It takes an incoming continuous CV voltage and converts it to the nearest note in a scale. Active notes can be selected with the 12 buttons. You can use it to tune the output of your analog sequencer, as a semi random melody generator, for fast chiptune arpeggios and much more.

It comes as a complete kit with all needed parts to build it. That includes a multi colour aluminum frontpanel, high quality jacks and illuminated bi-color push buttons.

The project is open source, so the schematic and source code is available
