I am having a very strange (I think grounding related) issue with my system. Basically the first time I plug it into my audio interface, everything glitches out and the audio interface disconnects from my PC. After 3-4 seconds the audio interface reconnects and everything sounds okay. Any subsequent connections between the eurorack and interface are totally fine. It is only the first connection that causes any problems.
Additionally if I touch the metal part of a jack socket on both my eurorack and the interface as I plug in the first cable, everything works fine. My thinking is that this must be something to do with the grounding between the eurorack and the interface? I have tried using different wall sockets for the power of each device but the issue remains. My flat is tiny so all sockets are probably on one circuit.
I am really not very clued up on this sort of thing though so was hoping some of you may have a better idea what is going on?
