The renaisance of modular synthesis meets visual programming with a new Arduino shield from Open Music Labs.
rePatcher is an Arduino shield that allows you to “repatch” your Max/MSP or Pure Data patches with a 6 x 6 patchbay matrix. It also has 6 general purpose control knobs for modifying parameters in your patch.
I could see this built out into a project box with stackable banana clips or 1/8” jacks. Think Korg Legacy Controller powered by Ardunio.
