Sorry, Lee, but if you are going to get picky, you are going to find trouble with any ROMpler's saxes. The T4's are some of the best, but I can still hear issues.

The really low notes sound good, but there's one REALLY low note that was weird, then the low note vibrato works at that slow dreamy tempo, but faster it is going to annoy you (sax players change vibrato speed depending on tempo and all sorts of other things). Then there's a sort of phasey sound in the mid register (and I've heard it on other recordings, it's not a video encoding issue) that bugs me, a nasality I don't like.

Some of it comes down to the fact he's not bending anything at all, and phrasing like a keyboard player, I've heard the same sound used on Yamaha's own demos to spectacular effect, but in the end, it ALWAYS comes down to one thing with sample sets... if you are prepared to play what suits THEM, rather than them try to suit whatever YOU want to play, you usually get good results. Heck, I've even heard good sax demos of Korg PA2's DNC sax..! As long as you play to their strengths, and avoid their weaknesses, you are good to go. Expose their weaknesses, though (as you can even with Yamaha's saxes) and they will still suck!

In the meantime, at least with a Korg, you can load some third party samples into it. I've heard some really good ones, for Akai. Shop around, and you may find yourself, instead of losing out on your favorite arranger features to go after a particular sound, you just load those sounds into RAM and keep what you have!
