Shakil,
As far as sound (primarily the demos I've heard), I think the Tyros blows away other synths like the Korg Trinity, Triton Classic, Triton Studio, PA-60, PA-80, Roland Fantom, VA series, and several other synths in the acoustic department.. Lets face it Korg has really gone down hill with their sound since this teeny bopper I wanna be like Britney crowd has grown bigger.. I notice that when people buy synths today, it's not because it sounds good but mostly because of who's using it.... Guess it makes them feel better about their purchase. As far as sequencing, I looked in the Tyros manual and I think it could use a little work. Yamaha still has yet to really nail it with the sequencers in ALL of their upper line arrangers.
