I love using my Gameboy's with my eurorack. Played with them all weekend. In this vid I added a voltage controlled NES for crazy flavor too.
Combined madness starts at around 2:00.

In the next version I am building now I will have CV clock sync out from LSDJ so you can control all of your eurorack sequencers with LSDJ. Should have it wrapped up in a month or so.
