The Toggle Quantizer is a single channel quantizer with a range of 0 to 10Vs. Each volt is divided into 12 equally spaced voltages, to conform to the 12 half-steps of a musical octave. An input voltage will be quantized to the closest of these 12 steps that's possible.

The only controls on the module are 12 toggle switches, these set whether a particular half-step in the octave is a possible quantized output. This lets you control the musical scale by turning notes in the scale on or off. On the right is an image of the panel with the corresponding notes for each toggle labeled. The module has only a single voltage input and voltage output.

Demos, build documentation, drill guide, are available here.

Unfinished panels are drilled by hand in my garage, they are bare aluminum that may be scratched.  They are intended to be painted, etched or otherwise finished later.

Pre-Assembled Modules are built after the order comes in.  Build time can be a few days or a few weeks depending on what parts I have on hand.  When ordering, please leave a comment at checkout if you have preferences on what color(s) the panel is painted.
