u4ia, you seem to be right!
Page 4: The Virus TI is real hardware, but with the included VirusControl software and a USB connection, you can seamlessly ?port? its engine into your computer for use as a VST/AU softsynth, making this the world?s first hardware synth with sample-accurate timing. Instead of your computer?s CPU, the Virus? onboard dual DSPs handle the work, as multi-channel audio data is streamed to the host application. You can also chain other plugins before routing to any audio output. *It?s even possible to send audio back to the Virus for synth-engine processing by the envelopes, filters, or fx.*
I take it the latter is happening through the USB connection. Great!
