<HTML> <HEAD> <TITLE>Verituner</TITLE> </HEAD> <BODY> This is in response to several points from the= recent Verituner discussion: 1. As to whether or not hardware is a factor in the Verituner’s perfo= rmance, the answer is yes. The Verituner 100 uses a dedicated Digital= Signal Processing chip that, for one thing, enables it to simultaneously me= asure up to eight partials per note. This is done in the background as one t= unes. 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, altho= ugh the fundamental of those pitches is measured. With this comprehensive pi= cture of a piano’s inharmonicity, the Verituner can calculate tuning t= argets that consider anomalies in the scale. The result is a more highly cus= tomized stretch for the individual piano. This accounts for the positive rep= orts of Verituner tunings, notably on small and poorly scaled pianos. 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 info= rmation it is gathering (as the piano is being tuned) if A4 is tuned first a= nd 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 conductin= g an analysis that will lead to a definitive recommendation. 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 Veritu= ner. Once the “complete” inharmonicity information is collected,= it is used for subsequent tunings, as long as the saved file is used. At th= at point sequence does not matter to the Verituner.   5. The Verituner’s Measured Tuning mode is used to save an aural tuni= ng. A single partial of each note, which can be selected by the user, is mea= sured 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 st= ore them in the tuning record. The real power of this is that the altered ta= rgets are used in all recalculations of the tuning. 7. Enhancement of the pitch raising mode is in the newest release and shoul= d result in significantly improved performance. The markers that indicate th= e starting pitch and the overpull target now lock immediately and stay locke= d, although they can easily be erased by the user and reset. Overpull percen= tages for three sections of the piano can now be specified by the user. Furt= hermore, the user can quickly tell the Verituner where the sections begin, a= nd the Verituner automatically switches the percentages as one tunes. It als= o 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 ca= lculates tunings, you can download the complete User Guide (in PDF format) a= t http://www.veritune.com/downloads.html   An updated version of t= he Guide will be available in a few days.
