This is a two channel quantizer module. Each channel can independently be set to 1 of 16 different musical modes. It has built in track-and-hold functionality, and quantizing can be turned on or off using gate signals. It has a voltage range of 10V and can process either positive unipolar signals or bipolar signals.
The PCB has PC mounted pots for easy construction as well as mounting holes for those who want to mount the PCB parallel to the panel. It can be built in systems running +/-12V or +/-15V with no modifications.
For complete descriptions of the way the module is used, and how to build it, including schematics and parts list; download this PDF file.
Boards are available now. Price for 1 PCB/PIC set is $18.
Unfinished eurorack
panels are available for this project, they are 12HP and cost $8 each.
There is
more information here about panels. If you're interested in drilling your own panel for
this project, feel free to use my
drill guide. That image should be printed at 300dpi for proper
scaling.
