Max 2 x stereo - serious bottleneck?

[klagga]

A question about a thing I?ve worried about for some time now.

Looking at the specifications at the Access website, I see the following: "From inside a host application, the plug-in enables the new VIRUS hardware to appear as a multi-channel VST/AU soft-synth with up to 4 sub-mixes (or 2 ? stereo)."

This is how I interpret the specs:
- As I usually mix every sound in stereo, if I want to mix the stereo sounds from the Virus with other VST-effects at the same time as I lay down some MIDI-recorded tracks, I can only mix two different MIDI-recorded sounds from the Virus at the same time.
- When laying down MIDI-recorded tracks, I?ll actually have to render the sounds from the Virus to audio every time I exceed the 2 x stereo limit.

This sounds like a serious bottleneck workflow-wise, don?t you agree? The DSP-powerhouse Virus TI won?t be able to send more than two stereo signals at the same time through USB to the computer anyway, no matter how simple the sounds are.

Prove me wrong, and I?ll be happy.
