Sequencer Mode (snow) - No audio output

[NoLie6]

Hi pros,

can I have a short help on this?
I am using a (noname) software midi sequencer. Everything is fine (virus snow is usb connected and switched in sequencer mode).

When I play the midi sequence at the pc I see that the note symbol appears on the display of the snow, but no audio output (on line out l/r) will be produced. I don't know why?

A had a look in the COMMON menu and saw that surround output was Off. So I select Out1 L+R, but with no success. My idea was that since the midi is send to the snow via usb, maybe the audio is returned to the pc also via usb. If so how can I change it to the real audio out?

Best regards
