My off the wall guess is that the piano either does not record key release data at all or does it badly or does not respond to key release data that was recorded correctly. I do not know what models do or do not use key release data. If this is the case and it is not fixable with a firmware upgrade, it might be possible to post process the MIDI files to "improve" them. If the piano does not respond to or does not respond appropriately to key release data it might be possible to lengthen all notes slightly to achieve a degree of improvement.
I probably have a program somewhere that I wrote that does this. If not, it should not be difficult to modify a similar one to do this. If this is something you want to try, I'll look through my huge folder of utilities. Messing around a little with such a utility would not be a huge effort but it makes sense to first get as much information about the problem as possible.
If would also be useful to determine if it is a key release problem or if it is a pedal problem. Does it happen to all notes with and without sustain pedal?

Hi Carol,
My Disklavier reproduces my playing fairly well as far as how hard to strike the note. But there is something that doesn't sound right when the note is released--sort of a cutoff staccato effect even when playing legato. Since the hammers have no contact with the string after striking, I would guess it has something to do with how quickly the solenoid releases at the moment of striking. When I got the Disklavier, I was so happy with being able to get an authentic sense of what the audience experiences when I play, that I overlooked this--but over time I realized that this was interfering with my enjoyment of the reproduced music.
My piano technician is Yamaha certified to work on Disklaviers, and has done several adjustments but was unable to fix the problem. I wrote to Yamaha years ago about this. I found out from either my Yamaha dealer or my tech (can't remember which now) that this was a design issue of early Disklaviers that was later fixed by a different solenoid or solenoid driver circuit, but that my piano was not upgradable.
I admit I might have this wrong, but I think this is what I heard, and since I got the piano primarily as a workhorse instrument, and the Disklavier part was a performance and teaching aid, it didn't worry me too much. But I keep hoping that Yamaha has figured this one out for my piano!
