Let me edit just a bit what I said to Tom:

... the sounds heard on the Yamaha Tyros3 website demos PROBABLY were the result of the performer's individual settings on his keyboard for that particular studio. In addition, the demos were PROBABLY processed through more studio equipment in the playing and recording process.

I did not say the rest of this paragraph, how could I know what is possible when I don't know what if anything was done.

In MY OPINION, many of the voices have too much reverb, but the compressor settings are fine out of the box. MY OPINION.
