Build Your Own Mechanical Patch Switch
A mechanical patch memory for modular live rigs. I made this when I first started touring with a synth, playing songs from 'The Inheritors', to let me reroute bits of my synth differently for different songs. It has 8 states. In each state each of the 7 inputs is connected to either its A or B output or nothing.

I now use a combination of my own software and an 'Alysseum matrix II' module to achieve a much more flexible version of the same idea.
