I just picked up an MC8 to use with my Riverside (trs), Timeline, and Specular Tempus. Everything is working as expected and you would be surprised by the amount of options I have with this setup. My only issue I have is when I connect my Riverside to the MC8 via TRS cable it instantly introduces a high pitch digital whine. I have had this issue before when powering pedals on a daisy chain style power supply but I’m now using a Cioks DC 10 with all isolated power and have had no issues for years.
I just wanted to see if this is something that is common and an easy fix? I have tried every different power supply setup and swapping around, even using separate power for all the pedals with no luck. My only assumption is that plugging the Riverside into the MC8 is introducing some sort of new ground loop. I’ve thought about getting some sort of Midi Splitter to just run everything out of the standard Midi out but that defeats the purpose of the 4 ssignable TRS jacks that made the MC8 so appealing.
