Jack-o-mix

This is a byproduct of MidiALF/CV project: I was testing the fab’s ability to handle plated slots and ended up with what looks like a pretty useful tool to convert 1/4″ cables to 3.5mm and back. Instead of maintaining a bunch of mixed jack conversion cables it’s now possible to just run regular ones through this tool.

  1. We had contact via email, my order is on-hold awaiting CV board. If possible I’d like to add 4 of these. Question: why not have 8 socket pairs?

    • If you have mixed modular environment: Euro and MOTM, or just want to interface Anushri to MOTM, you have to keep around a bunch of 3.5mm to 1/4″ cables. With Jack-o-mix you can just use regular 3.5mm and 1/4″ cables you already have and connect them through Jack-o-mix.
