Thanx 4 ur reply leszczu,
You see i already have the setup you've mentioned...My PC is tweaked to the max!!!
To understand the situation, here is the message i've send to customer support:
"Hi Joerg,
It would be great though if you could just adjust the latency settings a bit more when LIVE button is enabled so that clicking dissapears totally.You see i work with a midi foot pedal(imagine Kid Beyond style)and switching from track to track brings that clicking.Of course with LIVE button enabled things are better but not perfect.My question has to do with this perfection..

So sorry if i'm asking too much...
Thanx for the support
Yorgos"
and the answer:
"Dear Yorgos,
Thank you for your email. What we already tried to implement with the "Live" button is already the maximum possible. I can only repeat what I stated already in my first email: what we do here with integrating a hardware synthesizer in a software environment is anything but trivial."
So,conclusion comes to this...
If you play with your Virus on stage Kid Beyond Style use it in a good old Midi
fashion way
Cheers!
Yorgos
