hi,
i'm french so my english is not so good too...
here's how i do...
-create ONLY ONE channel strip with the virus plug in logic (by default midi channel multi)
-select this channel and in logic, track>new track with next midi channel (should be channel 2)
try play midi on this channel... and normally you've got the second channel of virus control who works!!!
if the channel 2 works but no sound ,"ctrl+clic" on the "D" under the mute button and select the output channel who you use... or change the default output in VC in the "common" tab...
do the same for all others channels to get 16 !!!
hope it's usefull for you...enjoy your virus!!!!
