Surely the problem is only one copy of VirusControl running.

Shouldnt be an issue to run 2 x TI's on one machine. Just the second one wont be 'integrated' and can only be connected VIA midi.

Yeah but if you installed two VirusControl VSTi softwares to two different destinations/folders within your VST Sequencer software plugins folder surely it would work,it does with a normal VSTi.
I would rather invest my money on a Plasma 42 inch Flat screen with DVi input

I wouldn't get a polar and a desktop if I were you, if you've got money for another synth I'd suggest a V-synth to go with your Polar.

+1 for the v-synth

TI+V-Synth is a great combo :)
