Translated from dutch here is a review from the dutch dealer demonstration.
http://translate.google.dk/translate?u=h...en&hl=&ie=UTF-8 Bart the reviewer is a Roland player himself and on these dutch boards knowdn for being a Yamaha criticaster in the past. Yet now he is really possitive about the T4.
Calling it much more then a minor update and talking about the first time he actually heard drums in a Yamaha style.
Updated the link from babblefish to Google translate thanks for the tip
