Hi Babette,
I had Tyros 1,2,3,4,and5 and loved every one of them as to me they were the best on the market but time dose not stand still and technology improves and operating systems become better and more convenient to use. We all see this in Genos and that is why so many of us have changed and are pleased we did. You will see some music forums where it is nearly all Genos keyboards that are being used where as before it was mainly Tyros 5. The same thing will happen with the SX900. For those wanting a 61 note keyboard and three right hand voices with lots of other additions there dream has come true. The price is around what Tyros 1 and2 was but with lots more content and new features.
Time moves on and so should we.
