key double striking on New U1
Mark Mandell
The aftertouch could be a little excessive(if for instance the hammers
are too far from the strings) but I'd have the tech check for excess
lost motion as well as the let-off distance.
Off hand, I can't recall if Yamaha changed their types of hammer springs
but in the older ones with the Schwander actions where the springs were
attached at the rear of the hammer butts, the tension was often weak
enough such that double striking wasn't at all uncommon.

months looking from Savannah to Orlando at various brands: Yamaha, Schimmel,
Boston, Kimble, Kawai, and Baldwin. I decided I liked a $250K 9'
Bosendorfer the best, but my husband said he would get tired of eating
Hamburger Helper the rest of our lives. Instead, we chose the U1 for its
action and tone. Wow its a beauty, but when playing very softly some of the
hammers will double strike the strings. Is it normal for a new piano's keys
to double strike? The piano tech will be back to tune and make any
adjustments in a couple of weeks.

It's not normal. Sounds like he needs to up the after touch a little. Could be
something else. He should be able to figure it out.

when playing softly is indeed a problem with Yamaha verticals. However, I was
in a piano store yesterday where I was shown and I played a new U1 which has
been updated with features from the discontinued WX1 (minus the X-back).
According to the salesman the actions have been modified to minimize the
double-striking tendency. Jim In article

Unfortunately, my U1 is the NEW updated version and it double-strikes.
However, I am hoping my tuner will be able to remedy the situation.

when playing softly.If all contingencies have been exhausted and the problem
still persists then it is time for Plan B.
The damper springs are probably too strong.

That's a new one for me, Gary. Can you help me understand the cause/effect?

The damper spring tension on many new u/r pianos is so strong that the
smooth forward motion of the whippen is hindered when the spoon cotacts the
damper tail.
This results in the sluggish speed of the jack which can't clear the notch
and causes the hammer to bounce. This is very noticeable when playing
softly.
Try this. If you find a double striking hammer on a new piano , lift the
damper with your finger and play the note again. I bet the hammer will now
check properly.
The damper spring tension should only be enough to dampen the string
efficiently whilst causing as little key resistance ( touch ,feel ) as
possible.
Of course , the causes of double striking may be many but the above is
just part of the process of elimination.
