you also need for the Midi Jacks an adapter.
update 01/2020: ground the MIDI IN port too, that's needed because the acrylic's adapter to the stereo 3.5mm jacks are isolated
in case you use silver knobs: they are metalized and make grounding issues, you have to remove from the bottom the paint with a cutter knife.(easy)
the blue cable connects ground from MIDI out to the MIDI IN jack.
