The FSX keybed on the Tyros3 was specially developed to make the most of the new SA Voices, and the aftertouch really adds a lot of expression without having to use the Mod Wheel.

However, having used, for some time, a PSR-S910 with the same keybed as the S950, and some of the very same SA Voices, I was still very pleased with the overall control the slightly shallower and very light action gave me.

The S950 will also give you Wav and MP-3 playback with tempo and transpose control, and center voice cancel...if these features are relatively important to you, then the S950 is a good choice.

Like the Tyros3 and S910, the S950 does not have any SA2 Voices.
