I installed the glide kit to my Dark Energy a while ago and lately the internal midi-cv converter has been giving me problems. Every so often it just stops responding to any incoming midi signal, either through the USB or midi ports. I reinstalled the glide control and that seems to clear it up, and every so often I would have to remove and reinstall the thing to get the unit to respond to midi.

Today it stopped responding at all, so to troubleshoot it I decided to remove the glide knob to see if maybe it's faulty. In order to install the glide I had to remove in internal jumper, and now I can't find it where I stored it. Does anyone know off hand what kind of jumper I need to buy

Also if this is not a case of a bad glide knob, is there any place in the US that can repair the unit or will it need to be sent back to Doepfer

Thanks in advance for the advice!
