Hi
I want to share my solution for all Cubase users who want to use the Virus TI (in USB-Mode) without any latency:
-use the Virus TI VST2 version in live mode
-load an appreggiator preset and play it in a loop
-add a kick to 4/4 (or your favourite style 
-when the beat seems not to be in sync (or is stuttering) to the kick add the midi-insert-effect "quantizer" to the midi track
-you can correct the latency with the "delay" effect at the bottom of the plugin (my latency = -19ms)
(make sure that the "note quant" function is "off" when you want no influence to your midi notes)
I use this effect over all my midi tracks which are routed to my TI
Maybe the picture can help you to understand what I mean:

Anybody using the same solution?
There is also a free Voxengo plugin for latency corrections!
stay tuned
