Verituner is an advanced piano tuning app for use by professional piano technicians. This new app brings our leading Verituner product line to the best ever platform in its 15 year history.

Piano technicians have said that Verituner technology has given them better sounding tunings than they ever thought possible with the fewest steps. Our patented multi-partial technology calculates your tuning to perfectly match each piano’s unique scaling. Automatic hands-off operation keeps you tuning quickly and eliminates tedious pre-tuning measurement steps.

• Aural Quality Tunings – create well-balanced tunings with the only tuning technology that tunes all the partials on all the notes.
• Quick and Accurate Pitch Raises – get close quickly with overpull targets individually calculated from the starting pitch of each note.
• Historical Temperaments – get access to over 90 of the best known historical temperaments, or easily key in your own custom temperaments.
• Adjustable Stretch – precisely control octave widths with the built-in Styles, or create your own Custom Style to exactly match your aural tuning preferences.
• Alternate Standard Pitch – tune to alternate pitches in a wide range of A=392 to A=466.
• AutoNote – jump to any note and octave as you tune with automatic hands free tuning.
• Saved Tunings - instantly recall prior tunings so you can tune quickly and consistently on frequently tuned pianos.

Verituner measures the inharmonicity of every note while you are tuning, accumulating a detailed picture of the scaling of the entire piano. Then it calculates tuning targets for all the partials of all 88 notes to produce a well-balanced tuning custom fit to the piano. By tuning all the partials, the best possible compromise can be reached for every tuning interval, and the need for aural adjustments is substantially reduced. All of this is done completely automatically while you tune – without any extra steps required.

The answer is yes! BUT… Piano tuning involved advanced skills and experience. A beginner will be challenged with correctly interpreting the moving tuning displays, and performing very fine tuning pin movements that a professional takes years to perfect. If you are an amateur, please contact us to understand what to expect before purchasing this app.

If you have any questions about the Verituner app or need any assistance whatsoever, please visit our website and contact us by email or telephone. We are always happy to help!

It’s all about what’s under the hood

I love the Verituner. One of its most unique features is that there are several programable components that will help you style your tunings. These different changeable variables empower you to employ your own taste. If you are a practiced aural tuner— this is great. There are temperament options (including custom definable temperaments). While tuning, there are automatic Inharmonicity stretch calculations running throughout the tuning process until no more information on partials can be gathered by the app, and finally a “ style “ option, which effects how to handle the collected data from the partials it hears.

There are a few good EPT machines and apps. I used a Sanderson accutune machine for a number of years with great results. For the apps, Tune lab costs less and RCT costs more. I found it difficult to decide on one so I downloaded the user manuals of all three knowing they can all do a great job. RCT has a very friendly looking graphic UI, but I could not see how any of these others, within their literature, could compare with the number of variables and variations you can employ in the Verituner app.
It’s worth tinkering with and understanding how each variable effects the outcome, and after a few months I’m really getting amazing results, and can alter the style of my tunings to suit the customers needs.

Love it!

Have used it for the past five years, and am so glad I got it. To me, some of the best features are how it deals with the everyday situations of poor-quality scales and raising pitch. It can take a poorly designed string scale, and with subsequent tunings keep measuring acoustic information and calculate a tuning that will “iron out” problems. The overpull function yields an incredibly accurate tuning, and has saved me untold hours of work. A great tool for the tuner who tunes for a living

Professional tuning software

I am a piano technician by trade, I trained at a school who had the developer of this software teach us a class all about it and the math behind it. Let me tell you, it is highly sophisticated and worth its weight in gold. In the school we used it to test our aural tunings and it did that amazingly. Using a spreadsheet on the computer we were able to input numbers of our tunings measured and saved with the Verituner, and the spreadsheet gave us a graph of exactly where our mistakes were and how bad they were! Very useful for a budding tuner.

Using the software to tune a piano I can do 4+ pianos in a day (depending on their proximity to one another!), and I am ALWAYS satisfied with the results. I am a professional, and this does its job without breaking a sweat, makes me look great, and has taken my tuning time from 2 hours to 1, except for the occasional pitch raise.

There is practically no setup, and you have the option to tune in a wide variety of temperaments which is great because I also work on harpsichords, fortepianos and other historical instruments. As well as having the ability to save tunings which honestly I don’t use much. But I could if I wanted to!

If you are serious about piano tuning and want the proper software to do it well, improve your craft, and diversify your toolbox, this is definitely it. It will pay for itself in short order. I owe much of my success in the business to the skills I’ve developed using the Verituner and the people who showed me how to use it.
