Yamaha's SA/SA2 is so darn good because it is very easy and intuitive for the player to trigger nuances in the selected sound while still being able to play chords in the left hand.

I have had many pro synth players try my Tyros4, and the Saxes blow them away every time (pardon the pun).

So do the other wind instruments like trumpet and clarinet, and they simply adored the guitars, both acoustic and electric.

All say they wish they had the same easy to use, and super expressive voices on their synths.

Can't say I blame them.
