Disklavier

Hi

I'm new in this forum, so I tell you who am I. I'm François, a french composer (so please 
excuse my poor english), 42 years old, and I bought a disklavier -Mark lll DU1A- in order to 
have a better sound for my work (mostly for theater) than a digital sound of piano.

But I'm a very dissapointed, not by the sound of the piano itself, but by the "woody" noise of 
the keys when they return to original positions (i.e. when note is off). I am working now on 
very light piano part (the same universe as, for exemple, Arvo Part's "Für Alina"). I play very 
softly, but when the disklavier replays, the velocity and the softness is respected, but the 
notes-off are brutal, and it makes this woody sound that is amplified by the piano itself.

Has someone had the same problem, and can it be resolved ? I'm sorry if this subject was on 
the database, but I searched for it and don't find.

Thanks for help
