Please help me understand...

I don't know the answer because I never use my Snow's multitimbrality. If I did, I would have definitely bought a TI or TI2. I know that the Snow isn't the best choice if you need live multitimbrality or sound stacking (which is basically multitimbrality on the same MIDI channel.) I think the Snow is the perfect studio Virus: lay down a track, freeze it, go on to the next one (but in truth, I rarely use more than one Virus track...)

Off the top of my hat, I'd say that for your needs you should consider selling your Snow and buying a used TI. You'll probably only need to add $200-300.
