Diki,
"If it sounded great on the DVD, you CAN make it sound as good yourself"

Yes you're right, you should be able to do that.

I've listened to the part in question on that DVD and I think some of the answer is in the technique used i.e. lots of notes played, use of the great sounding lower register, basically lots of stuff going on.
The problem really shows up when a single note melody is played between F3 to E5, it's then that the true quality or lack there of becomes apparent in the mid range of this sample.
I�ve heard a CVP309 piano; I think the sample size was around 110mb needless to say it was a heck of a lot better than the T3 �Concert Grand�.

Thanks for your ideas; I�ll play around with your suggestions re. velocities etc. and I�ll remove any EQ and compression and try it all again to see what comes of it.
Thanks again,

Chris.
