Im not really familiar with FL...
I guess you just need to make sure that FL is not filtering any MIDI data. Also, go through the Virus Manual, there are a couple of settings to adjust for when you are working with a sequencer (something about hi-page/lo-page). Make sure that your MIDI in/out ports are set on your MIDI channel in FL, make sure that the patch has the same MIDI channel as the FL MIDI channel....
Ummm..... The thing is, there could be so many things that could be the issue. It is hard for anyone to narrow it down. You just need to do some trouble shooting. The soundcard/MIDI interface should be OK, so make sure it is not something simple that you are overlooking.
Good luck dude!
