where does your output from the virus go ? usb audio will not work, mystery has no recording functions, so only analog or digital outs serve
When using the SimpleVirus USBdriver - I can't route the audio to get sound from anything - the VST nor the Mac Speakers.
But when I go back to the Roland UM-ONE and Steinberg UR22 setup it all works perfectly.
I just don't have enough knowledge to get it working any other way.
