My = brain was fixed on the fact that if there was a base it had to be used. = O:( Hey #7 below is goiung to make the pitch raise a lot easier for me. Locking in the target until ready to go on. Will this still leave an = auto advance? I have been using the numbers and doing the math in my head as I go.

As to whether or not hardware is a factor in the Verituner's = performance, the answer is yes. 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.=20 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.=20 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.=20 4. It is important to understand that tuning sequence with the = Verituner is only a concern with with the first 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. =20 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. 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.=20 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. 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.
