I am a bit confused.
You are attempting to use the Virus Control component within Sonar? I presume that is for controlling the knobs and whatnots.
I looked at the support site for Access, and there are a total of ZERO articles on their site dealing with using Virus Control with Sonar.
Are you SURE this is supposed to work?
Also, the Ti2 will appear as a choice for midi input devices, with the name 'Virus TI Synth'. You should be able to add that in preferences.
So, please explain a bit more about precisely you are trying to hook up, so that I can better assist.
Thanks, sorry I am a bit denser than usual today.
