Terry, if you listen the tone to will  hear the shortening and the less rich
tone obtained with the coupling object. Even on Internet it is very evident,
it makes me think of the effect one have when muting the capo.

Why is it occurring I can't explain, the goodie is of course muting a
little, it also absorb energy ....

may be the inventor have find pleasing the fact that a better coupling is
giving a more strong tone to begin with or he likes the change in tone. I
often write about unisons tuning that we deal with the coupling all time,
and that is the characteristic we may learn to listen, for the coupling seem
to occur even if the strings are a little off, when at the same time the
string is on its way to stabilization, (second part of the extinction curve)
I believe that when we regulate the speed at which the coupling occur we
regulate the way the attack is stabilized, and then the way energy remains
for the last part of the tone. This is what say G.Weinreich without being
able to prove it, some (Steinway trained) tuners exacerbate that "leaning
tone " effect, others have a more pure tone, nowadays when you tune a piano
with many irregularities in hammer mating, you are sometime obliged to use
more than necessary that leaning string to hide the defective unisons.

For me, unisons mean purity and length but energy may be present also, I
don't leave any audible leaning string if I can, as I've find that this tend
to produce too much brilliance, and less warmness..

This is typically the kind of invention that makes me smile (not feeling
particularly superior in nothing, I certainly should had hard times myself
to design and commercialize such a thing). I get it as being "exotic" !

Did you hear the samples ?

Best Regards.

  Please explain further Isaac, what is it I should hear that would show the
device to be useless.

    I know I promised to stay nice and polite ,

    but this invention gave me a good opportunity to laugh (while it is a
little sad that people have spend so much time trying to commercialize such
a goodie).
    Listen to the samples with and without the "pitch lock" and you will
certainly - for most hear immediately why it is useless.

    On the other hand string coupling is exactly what we are after if we
want to tune long lasting unisons (and nicely toning piano) - also what we
get with voicing.

    A good Sunday to all.

    I'll read again before sending, to be sure.

    Isaac

    DEAR PTG CHAPTER PRESIDENT:

    My name is Scott Jones and I am pleased to announce a new product now
available to piano technicians.  PitchLock piano string couplers are small
metal bands that link or “couple” pairs of piano strings.  The joined
strings produce a single frequency, even if the individual strings are out
of tune.  As a result, unison tuning longevity is significantly increased.
The effect is remarkable.

    You will be seeing and hearing a lot about this new concept in the very
near future.  PitchLock will be featured in the February issue of the PTG
journal.  We will also be exhibiting and teaching classes at conventions
nationwide.  You can also learn more about PitchLock at our new website
www.pitchlock.com/home.htm  .    While visiting the website, you can preview
audio/video samples and  see this exciting new line of products.

    PitchLock technical presentations are now being offered  to PTG chapters
in conjunction with our convention travel schedule.  If your chapter would
like to see and hear the PitchLock effect in person, please contact me at
sjones@pitchlock.com .  I hope to see you at a regional convention this year
if not at your local chapter meeting.  Please look for the PitchLock display
or, better yet, sit in on one of our classes.


    Sincerely,


    Scott Jones

    President, PitchLock Inc.


    PS. For a free sample and literature about PitchLock piano string
couplers, just reply to this note and include your mailing address.
