Hi All - I have to totally agree w/Al on his summation - oops...have I mentioned that I am now a T4 owner? The T4 is AMAZING! I had the T2 for several years and believe me the upgrade was well worth it! The drums are indeed mucho better and I love all the new voices. When I pull up an older style, MIDI file, or registration and change the drum set to the new "live" drums, it makes a considerable difference. Every time I turn that machine on I am happy (ELATED!) that I made the upgrade. I, like many of the others, am not totally blown away by the (vocal) voices and voice-laden styles, but having been a Yammie user for over a decade, taking the voices out of the styles is an easy task. Overall, the sound of the T4 is so much better than the T2 I had before! Glad I did it and sorry I waited!
