This is the sourcecode for the Sonic Potions Penrose Quantizer eurorack module. The project page with more information about the module can be found here: http://www.sonic-potions.com/penrose

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.

The code has multiple separate parts:

• The root directory contains the Quantizer AVR main program
• The bootloader directory contains an audio bootloader for the AVR and a C++ program to generate .wav files from AVR .hex files

The code is released under the GPL:
