The T4 sounds great. The demos are very good and the drums have definately been upgraded. Loved that piano sound . I dont know if people with the T3 should be dumping them though as the sound and the styles are all too similar to each other. I think if i had a T1 or T2 the decision would be easier. Unfortunately the Tyros range still are inadequate for me in terms of an all in one arranger due to the under spec'd sequencer and sound editor but in a studio that would not matter.

Best of luck to yamaha. They have certainly created a buzz about their latest offering by the amount of comments here and elsewhere. They must be doing something right as far as marketing is concerned .

I am sure much great music will be made on the T4 as could equally have been made on the T3. Have fun whatever instrument you play.
