Ian,

This comparison really changed my views on Yami sound. T4 truely has much more dynamic sound than even the T3. I am very impressed and wish I could trade in my T3 for one now but that's out of the question until T5 or maybe T6 comes out and the going price of the T4 is where I can go for it. Interesting the other night I mentioned a birthday wish and before I stated my wife said "you want a Tyros 4" (not really what I was wishing but it's on track with this opinion).

Playing SMFs without editing anything is a very good way to compare units since their mappings to voices from GM SMFs are important when using backing tracks for realism and true quality sound.
