As far as the money. For example, the soprano saxes are incredible. Google the price of a Selmer soprano sax. The sax alone costs about the same as what we can buy a T4 for.
That's an excellent way of looking at the cost, Scott.
When we consider that on the Tyros4, we have
several terrific SA/SA2 saxophones of
various kinds (tenor, soprano, alto etc.) plus a multitude of other expensive instruments (the Single Coil Clean SA Guitar samples were taken from a $70,000 vintage instrument!!) not even including the acoustic pianos and Hammond B-3's, the monetary value of this instrument makes more sense.
I had extensive time on both S910 and Tyros4. The latter is quite in another league from the former, which, in itself, is a great instrument and a super bang for the buck.
