As to whether = or not hardware is a factor in the Verituner’s performance, the answer = is <I>yes</I>. The Verituner 100 uses a dedicated Digital Signal Processing chip = that, for one thing, enables it to simultaneously measure up to eight partials = per note. This is done in the background as one tunes. <BR><BR>2. The partials = of 76 notes are measured, a total of  464 partials. As Ron wrote, there = is no point in measuring partials in the top octave, although the = fundamental of those pitches is measured. With this comprehensive picture of a = piano’s inharmonicity, the Verituner can calculate tuning targets that = consider anomalies in the scale. The result is a more highly customized stretch = for the individual piano. This accounts for the positive reports of Verituner = tunings, notably on small and poorly scaled pianos. <BR><BR>3. We probably = haven’t heard the final word yet on the optimal tuning sequence, but in = general the Verituner can make the optimal use of the information it is gathering = (as the piano is being tuned) if A4 is tuned first and the tuning then begins somewhere in the center of the piano and proceeds upward by step, and = then from the center down. The current recommendation is, after tuning A4, = tune A3 to C8, then G# to A0. Dave Carpenter is conducting an analysis that = will lead to a definitive recommendation. <BR><BR>4. It is important to = understand that tuning sequence with the Verituner is only a concern with with the <I>first</I> tuning of a piano with the Verituner. Once the = “complete” inharmonicity information is collected, it is used for subsequent = tunings, as long as the saved file is used. At that point sequence does not matter = to the Verituner.<BR> <BR>5. The Verituner’s Measured Tuning mode = is used to save an aural tuning. A single partial of each note, which can be = selected by the user, is measured and stored.<BR><BR>6. A new feature in the = latest firmware release (a free download that will be available today) is the = ability to alter calculated tuning targets and store them in the tuning = record. The real power of this is that the altered targets are used in all = recalculations of the tuning. <BR><BR>7. Enhancement of the pitch raising mode is in = the newest release and should result in significantly improved = performance. The markers that indicate the starting pitch and the overpull target now = lock immediately and stay locked, although they can easily be erased by the = user and reset. Overpull percentages for three sections of the piano can = now be specified by the user. Furthermore, the user can quickly tell the = Verituner where the sections begin, and the Verituner automatically switches the = percentages as one tunes. It also automatically transitions the = percentages from the tenor into beginning of the treble and tapers it at the top.<BR><BR>8. For more information about the Verituner’s = operation and how it calculates tunings, you can download the complete User Guide (in PDF = format) at http://www.veritune.com/downloads.html   An updated = version of the Guide will be available in a few days.<BR><BR>David = Bauguess</FONT> </BLOCKQUOTE></BODY></HTML>
