Verituner Features

Verituner calculates your tuning to perfectly match each piano’s unique scaling

Automactic Hands-off Tuning

Verituner Hands-Off Tuning Start tuning right away! Just start with A, and the AutoNote identification follows you along to any note and octave for completely automatic operation. The Verituner determines the required stretch by measuring inharmonicity as you tune, so there is no need for a separate measurement step.

Accurate tuning display for every note

Fine Tuning

The Fine Tuning function gives you a super accurate tuning display for every note. Large pitch deviations are show by the direction of the needle, and small deviations are shown by the spinning blades. Simply play the note and adjust the string to slow the blades as much as possible. Then move on to other notes and the AutoNote identification follows your tuning sequence to any note and octave. The display is fast and responsive; it moves right with you for instant feedback. All partials are tuned and displayed simultaneously in a combined spinner that includes a continuous numerical reading of your cents offset from target pitch.

Quick and accurate pitch raises

When a pitch raise or pitch lowering is necessary, the Coarse Tuning function gets the job done quickly. The Verituner automatically calculates an individual overpull for each note in order to compensate for the effects of changing the overall tension of the piano. The Coarse Tuning function displays a cents gauge which quickly shows you a wide range of pitch surrounding the target note. When you first play the note, the starting pitch is indicated by the line marker, and the overpull pitch by the triangle marker. Simply tune the string until the two arrows line up. You can adjust the Zoom level of the gauge to accommodate either small or large (100+ cents) adjustments. If time is short, you can perform a one-pass pitch raise with fine tuning!

Aural Quality Tunings

Technicians say that the Verituner is giving them better sounding tunings than they ever thought possible in a short amount of time. That's because, as in traditional aural tuning, the Verituner listens to all the partials on all the notes. The Verituner is the only electronic tuning technology that measures the inharmonicity of every note while you are tuning, accumulating a detailed picture of the entire scaling of the piano. Then it calculates tuning targets for all the partials of each note to produce a well balanced tuning custom fit to the piano. The Verituner is the first tuning technology that can accurately compensate for scaling inconsistencies, especially in smaller pianos!

Historical Temperaments

The Verituner's default temperament is Equal. You can also tune with 90+ unequal temperaments that are stored in its Temperament Directory. If you select an unequal temperament, it will be saved in the current tuning file, and it will be in effect the next time you load the file.

You can also design, store, and tune with your own unequal temperaments or other historical temperaments you add to the directory. Simply enter the offsets for the twelve notes of the scale.

Adjustable Stretch

The Verituner allows you to set your own preferences for the amount of octave stretch in your tuning through its Style option. Each style sets the widths for various octave types and where they are to be used. There are 3 built-in Styles:


Moderate stretch. A generic style, probably the best choice for the majority of tunings.


The least stretch. It may be a better choice for spinets and very small grands.


The greatest amount of stretch. Use it on concert grands when wider octaves are desired.

Adjustable Stretch

For advanced users who want to go beyond the built-in Styles, one of the more powerful features of the Verituner is creating Custom Styles with its Style Designer. You specify exactly the type of octaves you want to hear in each section of the piano. Just as with built-in styles Verituner applies aural tuning principles and calculates tuning frequencies using the beat rates of coincident partials from these intervals. These calculations are made with an advanced algorithm that finds the best compromises for all intervals and achieves a tuning of your preferred stretch.

You can choose among different types of single, double and triple octaves, and the beat rates for each. Weightings are used so that compromises can be made among different interval types. Verituner blends your preferences to make a perfectly smooth tuning. Once a Custom Style is created, it can be saved for use over and over again on different pianos.

Alternate Standard Pitch

The Pitch option allows you to tune to a pitch other than the default standard of A440. You can set a deviation from this standard, expressed in either Hz (Hertz, cycles per second) or cents (1/100th of a semitone). A deviation from A440 can be set from A392 to A466 (-200c to +100c). If you set a deviation from the A440 standard pitch, the offset is saved in the tuning file. When you load the file later, you will be asked whether you still want to use the for all intervals and achieves a tuning of your preferred stretch.

Saved Tuning Files

When you start a new tuning, the Verituner automatically saves a complete record of the tuning in a file. If you do not assign a name to the tuning, it is stored with a temporary name and will be deleted automatically after 15 tunings. If you want to save a tuning file indefinitely for future use, it can be given a name and stored in a folder. A file contains the tuning's Pitch, Style and Temperament options, the target pitches for each note, and the inharmonicity information measured from the piano. File names can be used to identify the piano brand, model, location, owner name or location.
