I don't know what the wiring is, but they'd better use the Shield for ground because many panel-mounted 3.5mm jacks are grounded even if you don't solder to them. This would require the cable to be directional and have telescoping shield from one end and no connection on the other end.<br>
<br>
Now that I think about it, 3.5mm MIDI is a bad idea because it might be more difficult to maintain classic MIDI's way of avoiding ground loops. For plastic cases and cheap gear, it wouldn't be an issue, but for modules with metal faces plates, it could really get messy.<br>
