Hi Feelonics,
Did you sort out your issue ? I have just had same issue. My Virus has worked flawlessly for years and now won't connect when using in Ableton Live.
It just says "No Virus TI connected.", You need to connect a Virus Ti Desktop etc.....
Well, all I needed to do was a reset. Been so long since I had any issues, I forgot that was a thing. Silly me.
Fortunately, it can be cured easily by resetting the Virus. First, shut down your
sequencer application. Next remove all cables including the power cable from your
Virus and wait for 20 seconds. Then plug-in the power cable again while holding the
ARP EDIT key. This will trigger a reset. Last, plug-in all the other cables again and
fire up your sequencer.
