Well, I've never said the Yamaha instrument sounds / solo sounds don't sound good, in fact
they sound great, and so do your work and recordings.
But the styles play a kind of limited regarding peek and expression for my personal taste.
I'm sure there is features that let the user adjust or tweak this in any way or other, but
stright out of the box, as most of the demoes and uploads we hear are, it don't make me
run to the shop and buy.
After all it's the autocomp/styles who are the main rason I buy an arrangerkeyboard, if I
was any good piano or synth player, I would buy soething else.
The part about "punch" in the styles I think Ketron and even Roland G-70 do better than
Yamaha.

Cheers & Happy Playing
