Fair enough. It won't get much further then the answer you provided yourself:
"trust your ears then"
Do you prefer the sound of the unison or hypersaw, btw?
Don't think there's any right and wrong when approaching this. It's right when it feels/sounds right, so tweak away and don't be such a tweak head
I think you can choose 48k sample rate on the Virus ti, no? this should, presumably, push the aliasing a bit further to the right of the spectrum, making it less noticeable. Interestingly enough, the Virus has much larger definition then the good old JP does. A slight boost on the highs can help to.
