Disklavier

Thanks for all your responses, very clear and argued, even it's a little bit difficult to me to 
understand every term...

I am sure that my problem is not normal, and is not in the way of record the sound in itself 
(well, it is, in fact, but not at this point...)

When I stand in front of the piano, and just make a small record of a few notes, very softly, 
while carefully slowing down the up movement of my fingers, in order to test the capacity of 
recording the off motion of the keys, and, when it's recorded, when the DK plays and every 
note-off sounds like 'dum', 'dom', 'dum', and when I *see* the keys going up fast and full of 
"authority", I'm very confused ; can it be possible that :
1 - my first and very new DK has a serious problem, or,
2 - my sequencer (Digital Performer) is unable to pilot the DK
3 - Yamaha, with the very last model of upright piano, made a reduced software, in order to 
tell to the customers : "Hey, you want quality, buy the Mark IV model !!"
