Can you use Multiple Virus TI VST's in a single project? I want to play separate patches without bouncing audio.

Hi,

I'm trying to play separate Virus patches on separate MIDI tracks inside Ableton. Is this possible? When I open the second one, it says "Virus cannot be found", I'm assuming it all has to be done with the confines of one VST.

I tried exploring Multis, or PARTS. I couldn't find good info, or any video tutorials on them. Does anybody even use them? What are they for? Can I play separate patches with them?

I loaded up another patch on the (2) Part and can't get any audio from it. What gives?

Any ideas or advice? Thanks in advance!
