  1. this seems useful, but i think for the cost it should come with a breakout cable and breadboard or something because, clean wiring – i’d say that’s probably the most annoying part to diy. 🙂

    also how is it powered?

  2. Tubbutec are amazing, I have midi and sequencer in my korg polysix and poly 61 now. Excellent service and products no one else is doing. So much better than other products which remove siting functionality from the synths.
