I'm happy with the PSR S950, given its sounds and quality, especially considering the price. What's more, I "borrowed" from it the ones that the PSR S950 lacks, because it can read them perfectly. Besides, I had already tried a friend's Tyros 3 and, as I mentioned before, the PSR S950 has almost the same accompaniment styles. Learning to use it was pretty straightforward for me, because it is very similar to my PSR 3000. This allows you to listen to it immediately on an MP3 player, for instance. I also like the Audio USB function, which allows you to listen to MP3 files, to play along and also to record a song (performance) in Wav format. Yamaha has solved that issue with the PSR.S950 which provides several parameters to emulate quite successfully the magical sound of a Hammond with Leslie. I used to hate that my PSR 3000 didn't have any settings to resemble as closely as possible a Leslie speaker. By the way, I'd say the keyboard is all right, but nothing more. Let's focus now! I really like the sounds with super articulation: Their realism comes through very well, depending on the touch. Sigh! There's also Ketron, which is excellent…end very European, but it costs more or less the same as a Tyros 4!! (In this regard, I think Roland is the one that sounds more European, but the pianos of the brand currently lag slightly behind the competition). One of the rare defects that can I point out is that it lacks "factory" accompaniment styles in 3/4, but it's not really a deal-breaker, because I can always create my own with the Style Creator. I have no interest in electronic music so, consequently, Yamaha's more traditional styles and sounds suit me perfectly. I am musically inclined towards commercial music (rock, folk and a bit of jazz-blues). I used to have a PSR 3000 and I can certify that Yamaha has introduced real improvements, both in terms of sounds and functions, on this instrument, including many of the Tyros 3, especially when it comes to sounds. I bought it new for approximately $2200 in December 2012. I am here to "speak up for" the PSR S950, which comes out pretty bad in the previous review.
