Thanks
mitchiemasha no worries, it was more to do with the latest update supporting vst3 and selecting the viruses 3outs/1input option with cubase not being able to support the viruses input which works as a sidechain via USB.
In other words load cubase, load access vc and try selecting 3outs/1in you will see an error message to do with cubase not supporting sidechaining.
Anyway Im moving on and waiting for an update from steinberg if it ever happens.
Juist frustrating having an available feature thats not supported by a very popoular DAW host.
From the looks of things its a Steinberg issue rather than Access.
