My mistake. I had scripts turned off.
My impression is that much of the sound quality comes from the hall. The volume of the reverberated notes seems slightly higher than the volume of the initial notes. (Possibly the mics were slightly wre closer to the rear of the hall than to the piano?)
Putting the Wetness slider a little to the right of center will make the reverberated notes louder than the initial notes while keeping the initial notes audible. A popular, and free if you don't mind a nag screen, Reverb is the vst effect Ambience.
I may be wrong about the source of the sound that you want, however. Let us all hear what you create.
