Hi,

I'm a tuner - technician in Belgium and since a few weeks,  I
discoverd the mail list of PTG . Nice!
Apparently, lots of tuners are verry happy with the VT Tuner so my =
question is : where is it possible to purchase one and
what does it cost? Is it also possible to find more technical =
information? Here I never heared about those machines.

  David,

  Thanks for your comments. I am very happy to hear that you have a such =
good experiment with your VT100.

  Today I had to prepare and tune 3 Steinway D together for a jazz =
improvisation performance, and the tunings sounds amazing . Each piano =
with his own sound and personality, but a clearness and homogeneity that =
could not be matched by other methods (in a little time)

  What I appreciate the most using this wonderful machine is that it let =
me work naturally and don't drive my ears in a pre-defined curve or =
partial progression.
  It follows the piano, as we all do when tuning (but the death tuners =
who tune by A0 or A88 !)

  I have a comment for you, you said that you can start with any note, =
but the A4 is of great importance and is treated differently from the =
other notes (and gives the pitch you know !) , as Dave Carpenter have =
write many times, it is very important to begin with that note and =
obtain a complete iH reading on it before tuning any other.

  Welcome the happy vt100 users family !

  Regards

  Isaac

    I purchased the Verituner recently and have used it now for about a =
dozen tunings.  I cannot compare it to the RCT or Tunelab, as I never =
used them, but I will say that the VT does a marvelous job when compared =
to the SAT III.  It's ability to measure (or premeasure) any or all =
notes and up to eight partials of each note in order to calculate an =
inharmonicity curve resolves many of the complaints I had about the SAT =
III which, unless monitored very closely, sometimes delivered a less =
than satisfactory tuning to my ear.  Though I had learned to work with =
the SAT III very effectively by use of the DOB, two page memory for one =
piano, and direct interval tuning, I find the VT to be much easier with =
more predictable results.  =20

    The complaints listed earlier I find largely unwarranted.  One =
suggestion was that the VT required a two pass tuning.  That is not =
true.  You can premeasure any sequence of notes ( though it is suggested =
you always start with A4) including notes in troublesome transition =
areas and the machine will use the data to create a curve with smooth =
transitions.  Or, as I believe Ron Koval mentioned, you can measure the =
whole piano before you start tuning.  Not necessary, but It takes about =
5 minutes. =20

    Another complaint was about the pitch raise function, or coarse =
tuning mode as it is called.  The coarse tuning system requires lining =
up two arrows rather than stopping a spinner and is a bit awkward at =
first.  When used as a genuine first pass rough pitch raise, it does a =
perfectly adequate job.  Moreover, you can set up the display with three =
different levels of overpull which can appear simultaneously on the =
screen.  As you progress through the scale and want to change the degree =
of overpull depending on the section of the piano, you can just aim for =
the appropriate indicator.  These settings are preset to 10/30/36 % =
overpull but can be adjusted to your own preference.  I set mine at =
15/30/36 which seems to work a little better for me.  I pulled a small =
Yamaha today which ranged from 30c flat in the bass to 80c flat in the =
treble.  One rough pass, one fine tuning and the fine tuning required =
very small adjustments. =20

    The display itself is perfectly readable and gives a lot of data.  =
The large flat or sharp sign that appears if the spinner is moving too =
fast to see I found helpful. =20

    You can adjust the stretch "style" from clean (narrow) to expanded =
as with the SAT III DOB, but unlike the SAT III, changing the stretch =
style does not preclude the machine using the inharmonicity readings to =
calculate an acceptable curve.  My experience with the DOB is that you =
can actually put the piano a bit out of tune by selecting an =
inappropriate amount of stretch.  I have not experimented fully with the =
"style" settings in the VT, but my impression is that the machine seeks =
to find a balance between style selections and what the piano dictates.  =
I think that is a better system.

    The 300 page memory can be upgraded to 1000 pages for an additional =
cost (as Paul L mentioned).  There are presently a few glitches that are =
being worked out with the upgraded memory, but I wonder just how =
important the extra memory is.  If you believe that inharmonicity =
changes with weather, then you would want to recalculate at each tuning =
anyway.  If you don't, then since you can premeasure and a full 2 pass =
tuning is not required to get excellent results, I don't consider it =
critical. =20

    It comes fully loaded with a variety of HT's and as difficult as it =
is to admit, I actually like the way it tunes ET. =20

    The simple fact that it measures multiple partials (rather than one =
targeted partial) on a given note simultaneously and uses that data =
collectively and progressively to project a curve, puts it above any of =
the machines that I'm familiar with.  There are other features that I =
haven't mentioned, but I think it is truly state of the art.=20
