So, this may not be related to optical at all. I plug a stereo cable into the hi-hat pedal plug and it begins to show continuous midi activity without even plugging a controller in at all. I checked the cord and there is no faulty continuity which leads me to believe that it is either the MD board or the v.1.8 input board. I tried it awhile back and thought it might be the Hi-Hat controller, but now I am not so sure. When I plug the cable into the MD it immediately acts up. The MD no longer responds to the buttons until I unplug it and reboot the MD.
Any thoughts?
Regards
