Would like to use a microphone with a VST vocal harmonizer in a live setting. Would split the microphone output for main vocal(going to mixing board like any other vocal mic) and A/D input to the ck61, which would then route to the VST harmonizer. Problem is the A/D input always feeds the ck61 main outs. so I get double main vocals, plus the harmonized output from the VST.  Is there an option to have the A/D inputs route to the usb audio only? Everything works fine except the microphone from the A/D input being mixed to the ck61 main outs.
