| | Help. USB Ground noise
My RME BabyFAce and Roland Fantom-G don't play together. Rme is connected with USB to PC, and Fantom-G is connected to PC via USB for MIDI.
There is this whining noise that is usually heard from laptops without DirectBox.
If I unplug USB cable form either Fantom or RME the noise stops.
I put Direct Box to Fantom G with ground lift and to RME with ground lift, still no help.
