I very much wish the T2 had 76 keys. Many times I am limited as to the range I can devote to the left-hand voice. I have found myself using more auto-chord stuff than I want to because of the lack of 76 keys. So I do find it limiting. I got the T2 for the sound/rythmn possibilities but am constantly frustrated by a key shortage. I would gleefully pay for an 76-key Tyros or better yet an 88-key model. Sadly, I think Yamaha believes I am in the minority.
