Scott,

As you mentioned, in your initial post, the sound of an instrument, to each individual, is subjective, hence the different camps for Roland, Korg, Casio etc.

As Diki has mentioned, there is a lot more to the Tyros3(and Tyros2) than just higher quality sounds...3 voice layering and aftertouch being only two.

My favorite sounding arranger was the PSR-8000; I owned a pair of them, both kept up to the latest OS systems, but the lack of four variation styles finally made me switch to a PSR-2000 (of which I bought two) and from then on, I used MOTL arrangers for gigging and personal use.

Using an MOTL arranger isn't the burden it used to be, and it also has many advantages, only one of them being cost.

Certainly, the S910 does not approach the overall quality of a Tyros2/3, but it is close enough for my needs, and, again, I like the simplicity of not needing (or worrying about) an internal HD, and of course, having the built in speakers is very convenient.

I went with the S910, rather than buy my sample S900, to stay current with the new style format...all my old styles work fine, and I've still not explored the multitude I have I have on my laptop....plus, I'll be using the new guitar format to edit my present most used styles.

I don't miss three voice layering, I actually prefer the lighter action, and the sound is very, very good...especially if I make sure I use high quality speakers in stereo.

Ultimately, you must A/B the two instruments in question for yourself.

When I went from the PSR-8000 to the 2K it was an adjustment, but the benefits outweighed any negatives, in my case.

Yours may be different.

Good luck, my friend.
