Overview
Quantizer is an open-source printed circuit board by sebastianbeyer, from the sebastianbeyer/SO_quantizer repository on GitHub. It is a 2-layer board of 166.5 × 200 mm with 134 parts on 109 nets, routed with 437 tracks and 6 vias.
It is built around the LP2951-50D. Its parts include 52 resistors, 26 capacitors, 11 connectors, 8 diodes and 6 transistors. It belongs with the AVR (ATmega, ATtiny) boards of this library.
Main components
1README
README.mdKosmo format quantizer based largely on the kassutronics quantizer. I went for a different interface though, where you select the scale via potentiometer and with the second potentiometer (and cv input) you can bias the incoming voltages and therefore 'transpose in scale'. It still lacks a few scales.

Questions
How big is the Quantizer PCB?
It measures 166.5 × 200 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Quantizer use?
134 parts, built around the LP2951-50D. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Quantizer KiCad files?
From the sebastianbeyer/SO_quantizer repository on GitHub, at the commit this page was made from: the board is quantizer.kicad_pcb and its schematic quantizer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Quantizer design in my own project?
Its repository states no licence, so its author keeps all rights: ask sebastianbeyer before reusing the design.
