This is a unique module which uses trigger and gate signals to control a CV. It increases or decreases the voltage by a set interval or multiple of that interval. The interval is voltage controllable.
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 $20.
