I own a TI (not TI2)
If you are expecting to buy a TI and have everything coming up roses .. you should not expect this.
The build quality of the TI is great. I don't know about the TI2 but supposedly it is "lighter" .. so my guess not as as good.
Also, be prepared for a lot of headaches.
There is this dream of Total Integration .. but when you try to get things going .. be prepared for company A (Ableton) tech support to send you company B (Access) and back and forth.
(Both companies are in Germany and don't seem to go to lunch together.)
Also, I really don't care for a lot of the TI's mannerisms.
Back with the Virus A .. you got a hardware switch for the On/Off.
Everything is software based on the TI. No On/Off switch at all.
If you expect to buy a Virus and have all your wet dreams come true .. you might as well spend $4K on a new guitar and expect to sound like Eddie Van Halen after 1 month of practice.
Like him .. you will suffer and suffer .. and suffer some more.
If you are not prepared to suffer .. Do not buy a Virus TI or TI2.
However, if you are committed to the long, long ... long ... LONG hard road, then perhaps the Virus TI is right for you.
If you wish to consider another long road of suffering .. you might want to consider the Kurzweil PC3 series.
