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.

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!

I bought Dirk's piano tuner because of what I believe are diminishing standards of conventional tuning near where I live. I am not a trained tuner but am a perfectionist in piano matters. I can thoroughly recommend Dirk's tuner to anyone wanting to tune their own piano to a very high professional standard. The personalised stretch for my Model A Steinway grand sounds excellent, the tuner gives clear and accurate readings to within fractions of a cent and is easy to use. I had numerous Email discussions with Dirk before the purchase and found him always very prompt, professional, and informed, in his responses.

Thank you Dirk for a great product.

I've got Dirk's Piano Tuner few months ago. I am tuning my 218cm piano regularly with it now and I must say my piano was newer tuned better. Much better than tunings of my professional tuner.
Dirk's stretched tuning simply sounds amazing. You will have to adapt your ears to slightly wide thirds, but the fifths are more close to pure. The tuner itself is very simple to use and very precise. For nearly thirty years I was frustrated with most of the time out of tune piano, which is I think, the serious problem of all the sensitive piano players. Now it takes me four hours every month or so, and I am more happy than ever.
One month ago, I've tuned my friend's almost new Steinway D, and he was totally impressed.
I recommend the Dirk's Tuner to every pianist, who has some ability to handle the tuning hammer or has will to learn how to use it (I recommend a good quality carbon hammer). It will make your life much much better.
Go on Dirk! Thank you!

I'm in the process of getting familiar with this tool, and it strikes me how simple and extremely intuitive it is. In my mind anyone could tune a piano with this tool and a maximum of two thumbs!

I will report back when I'm done tuning the whole piano!

I have been using Dirk's Piano Tuner since late 2014. I have tuned my Steinway B six or maybe seven times with it. I was amazed the first time I used it and, frankly, remain so now. My tuning technique has improved dramatically and I can now tune the whole piano in two hours, plus 15-20 minutes setup time (setting temperament strips, etc.) I strongly recommend an external mic All in all I can strongly recommend this product.

Dirk's piano tuning software is by far the best designed, best executed, and easiest to use piece of programming I have ever encountered. Keep up the good work Dirk!

I use this to tune pianos for myself and a few relatives. It does a real nice job. I use to do it by ear, which was too frustrating for me. I am much happier using this program.

Dear Reader,

I tune my own pianos since 1974 with the help of several tuning divices.
Summer 2015 I was looking for a better tuning device because the built-in stretching of my old device was not satisfying any more. I bought Dirk's tuning device.
Result: my instruments sound SUPER; better than ever before !!!
Highly recommended !

Cheers to Dirk and Ben for the development of this incredible tool !

Many thanks, Wim Thijs
