This module takes an input from a trigger or gate and outputs a gate of variable length. It can also be used to extend the length of gate signals. Length of gates or extension can range from approximately five milliseconds to five seconds.
The module is designed to work with +/-12V and +/-15V systems with only a single resistor value needing to be replaced. The PCB has mounted potentiometers, so only 5 offboard wires need to be installed
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 is $8.
Unfinished eurorack
panels are available for this project, they are 6HP 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.
