I still have this problem
I just got my Virus TI2.. My problem is exactly the same. I came from using a Virus B and Snap mode was what I used to keep things level. For some reason I can't even manage to set the INIT Volume for individual parts with the TI. Its like it just completely ignores what I tell it to do! So annoying.. If I can't figure these things out this synth is useless for my live set up!
