Re: [disklavier] MPX 1Z (2001) 48" upright

Sam,

Also keep in mind that how a piano SOUNDS influences how you think it feels. For instance, if all else is the same and if one piano is more mellow than another, the mellow piano will feel "heavier" when you play it.

It can. It is a Yamaha U1.

That would be great, but don't action parts (and maybe geometry) change over the years? I'm referring to U1s from 1979, 1997, and 2001 - the 1997 and 2001 pianos, only four years apart, felt completely different. I'm hoping the 2001 model can be adjusted to feel somewhat like my other two.

That's great news, Bill. So, do you think action on two U1 DKV should be able to be adjusted so they are similar? The action on my MPX 100II feels great, the MPX1Z much different.

Sam,

If the action feels different when you are in Disklavier mode, vs when the Disklavier system is off, then my guess is the Disklavier volume setting is set to a -7 or lower. The low volume settings on older Disklavier uprights bring the hammers closer to the strings, which then gives a very funny, mushy feeling when playing it. Try raising the volume of the Disklavier up and the touch will return to normal.

Bill, thanks for the info. Can key dip be adjusted/regulated by a technician?
Also, the action felt different after self-play than it did when power was turned off. Is this possible?

The "small" key size must be some type of illusion, but it certainly felt that way. I will ask friend to measure.

Hi Sam,

The key tops on Yamaha pianos are the same width. It is easy to check. Simply measure from the left edge of key #1 to the right edge of key #88 and you will find them to be the same (about 48 3/8"). The exposed length of the white keytops will be just under 6".

Key dip - The distance the white keys are designed to travel on Yamaha pianos is 10mm - whether they are uprights, grands, Disklaviers or Silent pianos. The dip of the black keys will vary from 10mm a small amount, to match the aftertouch of the white keys.

I imagine that your friend's U1 Disklavier just needs to be acoustically regulated to spec.

Hello all,

I'm considering buying the above model DKV (U1 48" upright) from a friend. I got to try it out today and played it for quite a long time, as well as testing out disklavier functions.

I already own two U1s, a disklavier and an non-DKV upright.

While the disklavier functions seemed to work fine (sticky disk drive that finally worked) and the piano sounded good, the touch was somewhat strange - very light, with a shallower key-dip than my other U1s. Also, the keys actually seemed smaller! Has Yamaha changed their design that much? My pianos are from 1979 and (DKV)1997, this DKV is from 2001.

I started to get used to playing it and after a while enjoyed it, but I feel somewhat conflicted about buying it.

If anyone has experience with different model DKVs like this, or any ideas, I'd appreciate your thoughts.

Thanks,

Sam
