Revision as of 18:42, 3 June 2019

This is just a quick, photographic guide for the one or two people out there that actually have the CGS122 switched matrix or CGS123 switched matrix Eurorack boards.

A little on how it works

Partial schematic. The rest is simply more of the same.

Construction

CGS123 Circuitry PCB.
Rear of CGS123 Circuitry PCB.
Switch PCB. Note that only half of the resistor positions are used. 1/8 W resistors are required. All resistors on this board are 100k 1%.
Switch PCB. Note that only half of the resistor positions are used. 1/8 W resistors are required. The second resistor position is for a second matrix on the same board, allowing for stereo switching. The CGS123 interface board is only mono.
