So yeah, if you are looking for an ETD that really gives the "best" tuning calculations, especially for difficult scales, I haven't found anything to beat the Verituner yet. Without full information, this challenge is more difficult. The ETD stretch difficulty is still how to articulate to the software where to place each octave match so that the piano can sound the best. ETDs can with precision place an octave at a determined width of any particular partial match, but struggle to tell when just when an octave sounds "good". Accessing the custom stretch modes allows the tech to further tailor the calculation to the piano.Ī simple reason why this gets so complex is that while our ear may be able to easily hear when tuning an octave moving through flat, closer, closer, good, sharp, sharper(similar to how many approach unison tuning). Even in the default "Average" mode, Verituner is more responsive to the quirks of individual pianos. Verituner is really a different ETD in that the measurements are not boiled down to an inharmonicity constant, and it measures all the notes from A0-C7, so that a more realistic map of the scaling can be used to drive the tuning calculation. Tune and move on, or go ahead and tune it by ear are the usual recomendations. This is where TeeBach and many other techs find themselves. Except for challenging pianos! Enter the split-scale tuning mode in Tunelab and other ways to try to make the approximations more reflective of the piano. In all honesty, the guesses are usually good, and the approximations usually work out. (uh, oh, approximations?) Then the ETD uses those few constants to guess what the constants might be for the rest of the piano. After the direct measurement of a single string is complete, that data is boiled down to an inharmonicity constant - a single number "fudge factor" that approximates the inharmonicity data of the string. If you look at what Tunelab does during that process, it gives you an idea of how those ETDs work. Others followed taking 3, or 5 or more measurements of the piano to build that model of the inharmonicity of the scale. Sanderson Accutuner was the big step in taking measurements from the piano to build a scaling model of the piano that could then be used to create the tuning calculation. Sometimes it worked, and sometimes not so well because there wasn't any measuring of the individual piano - the maps created didn't match the specific piano - especially challenging scales. Next generation offered stretch flexibility with either dials or built-in stretch tables which began the search for the elusive stretch. Why Eb-Eb? A4 sits right in the middle and that range of the piano hardly shows any stretch when measured. While it is possible to tune a decent Eb-Eb temperament octave, the lack of any stretch means that pretty soon working out from the middle, the octaves will begin to beat. Consider the first generations, similar to simple "guitar tuners" that are all around. There have been leaps in progress for ETDs over the years. Any of the current crop of decent ETDs can be used to pitch-adjust, with varying requirements from the technician. TeeBach states that he is looking for an ETD to do the full calculation of any particular piano - allowing the technician to only focus on the unisons. It would also be helpful to hear any other comparisons in regards to these two apps.Įxcuse me while I go into ETD wonky mode! Please share your opinion on how Verituner compares if you have used it. I do a couple hundred pitch raises every year, and if Cybertuner helps me do less of them, that would save a lot of stress on my shoulder and wrist. Then just cleaning up some unisons is needed. This is possible as long as the piano is no more than 20 cents flat. The second reason is that from what I've read, a main advantage of Cybertuner, at least for me, is that using the Smart Tune function, one can tune a piano that needs a pitch raise with only one pass. This is one of two reasons I'm looking to switch apps. My problem with the app is that I'm not satisfied with how it tunes spinets and other poorly scaled pianos, so I started to look at other options.įrom discussions I found online, tuners seem to share the opinion that Cybertuner and Verituner are very capable of creating good tunings on poorly scaled pianos. I tune only the unisons by ear and let the app create tuning curves for me. I have been using Tunelab for quite some time now.
