Thank you, Dale, for posting these items from the CyberTuner website. It is good to know that Dean does not advocate one pass pitch rasies as the end result. Perhaps Duaine will do some more reading, and learn how to propoerly use his program.

RCT auto-measures each note and uto-calculates its over pull using each note's optimal overpull percentage from custom chart. New feature: you can now create, name, and save your own ustomized overpull percentages charts. 16. With Reyburn CyberTuner could I tune my own piano? Yes! You just need to learn how first, but learning tuning takes erseverance. To learn to tune well takes A LONG TIME! Having a RCT doesn't make ou a tuner, but RCT is an excellent teaching tool. If you want to learn more bout piano tuning get in touch with your local chapter of the Piano Technicians uild. http://www.ptg.org >From the CyberTuner manual pp 86-87 fter the piano is at pitch, we strongly recommend you to create another tuning ecord to use for your Fine Tuning pass. Why? Because a piano's inharmonicity is ffected by tension of the string, so after a pitch raise, a string's partial adder may have changed significantly. Furthermore, some thoughtful piano engin-ears” suspect inharmonicity is affected by the stiffness of the oundboard, which varies with downforce, which is affected by overall string ension. So for maximum accuracy, we recommend you calculate a new tuning record fter a pitch change of 10¢ or more. This effect has been noticed in climates here a piano's pitch changes a lot between seasons.

Because it's software, RCT can be easily revised, allowing constant nnovation. The latest version can be downloaded from the Internet. RCT creates super-accurate tunings from low bass to high treble because six otes are sampled (A1, A2, A3, A4, A5 and A6) at as many as four partials three imes each for a total of 63 sampled partials. All partials are automatically easured and recorded to a one-hundredth of a cent! RCT creates aural-quality tunings because it directly matches sampled partials exactly what aural tuners do every day. Small (and all scale-challenged) pianos never sounded better! RCT utomatically senses and compensates for short scaling in spinets, small grands, tc.
