This gate/trigger sequencer uses 3 position toggle switches to set beats to Yes, No or Maybe. Beats set to Yes produce output, No produces no output and a maybe will sometimes be a yes or no. How likely a Maybe is a yes is controlled by a knob and can be modified by external CV.
The module has PCB mounted toggles, pots and LEDs for minimal wiring. It can be used with 12V or 15V power systems.
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 a 2 PCB / 1 PIC set is $24.
Unfinished eurorack

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.
