<BR><BLOCKQUOTE TYPE=CITE style="BORDER-LEFT: #0000ff 2px solid; MARGIN-LEFT: 5px; MARGIN-RIGHT: 0px; PADDING-LEFT: 5px">There is a first consideration to pursue before addressing the
<BR>proposition that "EBVT tunings cannot be accurately represented by
<BR>cents offset from ET." That is to get the person who says this to tune
<BR>a piano in EBVT, erase the tuning, have him/her/them tune the piano
<BR>again and see if the two tunings are the same. If they are, and if
<BR>the tuning was done by ear, that is one thing. Then I suppose you
<BR>could bring in the machines to record it. If he can only tune by
<BR>machine simply ask for the offsets used. What more can you ask for?
<BR>For any tuning to be considered for performance or artist purposes it
<BR>must be rendered consistant from piano to piano. Other wise what use
<BR>is it? If a single set of offsets cannot satisfy this criterion then
<BR>forget EBVT at least as far as machines are concerned.</BLOCKQUOTE>
<BR>
<BR>I and at least one other person have explained this before but I guess the
<BR>message just did not get through. I'm sure that a set of offsets can be
<BR>determined that would approximate the aural EBVT that I do or the way I do it
<BR>by the Direct Interval method using the SAT. But what *none* of the smooth
<BR>curve calculation programs that I know of can do is Tempered Octave system
<BR>that I have used now for some 15 years (and by the way, have proved many
<BR>times over that I can do it with the same consistency whether aurally or
<BR>electronically).
<BR>
<BR>In my aural instructions, it says to make the A3-A4 octave a 6:3 type. Then,
<BR>if you follow the instructions through to tune a temperament sequence from
<BR>F3-F4, that octave will be a perfect 4:2 type. As you ascend and descend the
<BR>scale of the piano, there will be octaves of varying sizes throughout. As
<BR>far as I know, all of the programs there are create octaves that vary in size
<BR>only on a gradual basis, not from one note to the next.
<BR>
<BR>Having already addressed all of the accusations of incorrectness, unethical
<BR>behavior and insanity, I can only say that if someone comes up with a set of
<BR>"Correction Figures" (as they are usually called) and uses them, thinking
<BR>that the result will be what I do, day in and day out, that person will have
<BR>results that do not match what I do in any way at all.
<BR>
<BR>I tried the correction figures that Mr. Scott supplied some time ago and
<BR>wrote that the results were not at all accurate. Now, I not being a person
<BR>who ever has used an FAC program and got paid for doing so, I'll hold open
<BR>the possibility that maybe I didn't know how to do it right. But even if I
<BR>did and Mr. Scott's figures turn out to be correct, the issue of tuning
<BR>Tempered Octaves as I do will still not be satisfied, therefore, I still
<BR>maintain that no one can do what I do with that kind of approach.
<BR>
<BR>I also, however hold open the possibility that with Mr. Scott's computer
<BR>expertise, he could eventually duplicate the Tempered Octave system, it will
<BR>just have to be another kind of approach that is completely different from
<BR>that which is used to tune ET.
<BR>
<BR>Any person using an SAT to tune a Victorian temperament from Owen's book,
<BR>Tuning or a Victorian-like temperament such as the Coleman 11 will have a
<BR>result that is far different from what I do even though on the surface, the
<BR>EBVT, the Coleman 11 and one of the Broadwood temperaments appear to be
<BR>similar.
<BR>
<BR>The EBVT with Tempered Octaves is an entirely new approach to the tuning of
<BR>the modern piano. It must be studied to be learned and should be done first
<BR>aurally but an Electronic Tuning Device (ETD) such as the SAT can be used to
<BR>assist, verify and store the tuning as may be desired.
<BR>
<BR>Please don't try to use an FAC type program to attempt the EBVT with tempered
<BR>octaves, it won't work because it is not based on the same principles.
