working with etd's and the customers' la-di-da

[David Love]

I did try Ron's style settings and contributed some of my own.  I think
Ron's settings were very good and I tuned with them a fair amount, but
recall that they were designed to agree with what he heard and vary from
the default settings which were designed to agree with what somebody
else heard.  I think we can all agree that different pianos need
different degrees of stretch and all the machines have different styles
built into them to try and accommodate those differences.  The SAT III
has the double octave beat settings, the VT, Cybertuner, etc., all have
stretch settings.  These styles that are preprogramed can't possibly
cover all of the variations that exist from all the different scalings
on all pianos.  They are designed to cover the range of pianos out
there.  While the VT offers the nice feature of customizing each
setting, it is not practical to try and tweak endlessly each style to
make it perfect for a particular piano.  

One thing to consider in this discussion is that when a piano is set up
for the RPT tuning test they don't use a canned tuning based on any
machine's particular default or even custom style.  Those who set up the
piano go back and forth with machine and ears in order to determine
where exactly to put the notes and then those placements are transferred
to a machine's memory.  If it was so easy, we would just run the test
according to whatever machine gets it exactly right.  The problem is,
none do.  At least if we are picking nits, which we are.

David, have you tried Ron Koval's custom style profiles on the VT? If
you
haven't, you will enjoy them. If you have, I'm surprised to hear your
comments.
