I ran into a problem with RM100 this weekend - the midi stopped working on my head - in checking into the problem it seems that the head does not power a midi controller anymore. I have a GCX/Ground control system, midi out of the GCX into a Digitech GSP1101 and out of the GSP into the RM100 - well it seems that whatever happened to cause the problem also caused the GSP1101 midi out to cease to function. Has anyone else had this problem? Is it possible that to damage other equipment from the RM100 midi in, as I was using a midi patch cable that had all 5 pins connected? Also it sounds like (at least from searching the forum) that I can only get the fuse for phantom power on the midi - is that true? It seems I will have to find a good local repair center - as I have a RM100C that is not working and I will need to get it fixed.
