No dis-respect meant to Terry because my situation could be shear fluke… but was doing a gig with 2 other dj’s and 2 of us had some weird ground hum. My other half had bought me some DJTT Usb Cables for Christmas that I had never used but were in my bag (always carry spares).. I swapped the cable from my laptop to controller with built in s/card and my hum stopped.
Like I said, maybe shutting down fixed it and maybe my other half is a sucker for paying higher prices but it seemed to work for me on that occassion. Terry please post if what I am saying is wrong because I don’t want to mislead anyone.
