Simply requesting the feature: Let MIDI out work while connected to USB, please!
Thank you mitchiemash for explaining how to do this below. I still would love to see the MIDI connections work on the virus without having to setup routing thru my DAW. Could this be a global parameter option? My menu free OB6 even has a MIDI option for "USB, MIDI, or Both" I like to believe if an analog synth can do it, a digital synth can have this option added on.
