When i bought the quantum 2626 i connected all my korgs and moogs and the korg minilogue xd and nts1 when connected to the line input create a loud digital hum and noise and its only on korg products so far moog and berhinger synths do not have this issue.
any suggestions? also it did not happen on my saffire pro 40 just your presonus 2626 quantum. settings?
