I have been using Dirk's Piano Tuner for more than three years and am very pleased. The calibration of the tuning scale makes it easy and fast to match the program's suggested stretch modifications. I tune my piano about every two months with complete personal flexibility of my schedule. This is great and sounds as good (or better) than tuners I've hired.

I just used Dirk's Piano Tuner for Windows for the first full tuning. It is VERY accurate and the graphics plus digital display make it easy to determine the exact point at which the ideal pitch for each note has been attained. To me it is the most helpful with the highest and lowest notes, and it is great to not have to lay the bearing or guess at what the ideal stretch is. The result was great!

I've tuned several pianos using the piano tuner. The results have exceeded my expectations. Professional musicians and amateur both are satisfied with the over-all temperament.
Thanks for a great tuning tool for those of us that don't hear as accurately as we once did.

After my first experience of tuning my own piano, (an upright SAMICK S-108s bought in 1991), I can say that it is a very good and easy to use application. The piano is perfectly tuned. The disadvantage is only that the first time you tune a piano, a lot of time is needed for the recording, and then the tuning. This took me more than 2,5 hours, maybe also because it was my first experience.

Had a problem with the microphone but it was fixed within a few hours. Thank you.

This is a very accurate and useful software. The calculated stretching is excellent on all sizes and types of instrument. The support is great and fast.

This guestbook is already full of positive comments, so I can be short:Dirk's Piano Tuner is a great program. With a bit of patience you'll tune your piano perfectly, and will make the sound of it sparkle, even if you never tuned a piano before. (If it's the first time you tune a piano: foresee at least half a day; the next times it will go considerably faster). Dirk's service is great. My computer broke and I lost my installation files. After sending a mail I received the next morning already fresh installation files. Thanks Dirk!

What great user support! Emailed about Piano Tuner not working after MacOS upgrade to 10.12. Had a response in 30 minutes (1 am NL time), new download with the problem fixed.

And, of course, the software works great. I have a professional tuner come in once or twice a year, because he has a super ear and makes my Boston grand just sing. But in between times I can touch up and keep things sounding pretty good. Thanks, Dirk, for a great product!
