This module is a PIC based 4x4 patching matrix. The four inputs on the bottom are routed to the four outputs on the right, and the routing pattern is controlled by the pushbuttons. Patterns are saved to one of sixteen memory bank slots which are selected with the knob on the lower left, these are saved and loaded using the pushbuttons. The module is powerful and easy to use.
The board features PC mounted pots, LEDs and pushbuttons for less wiring, but jacks are mounted off board so the design is friendly for 3.5mm, 1/4" or banana jacks. There are Eurorack and MOTM power connecters. It can be built in +/-12V or +/-15V systems without any 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/PCB/PIC set is $26.
Unfinished eurorack
panels are available for this project, they are 14HP and cost $9 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.
