I experienced Dirk's PianoTuner as a well designed and easy to use program which gave me great results when tuning my grand piano. The documentation was also very helpful with good instructions and explanations of the tuning works. Thank you for a good tool.

Ik heb al 30 jaar een Kawai vleugel 2,25cm gekocht in de lokale muziekzaak. Ik ben er zeer tevreden over, maar de stemmer van die zaak was niet goed. 10 jaar geleden heb ik mijn vleugel een goede revisie laten doen door Clavis in Utrecht (voorheen Goldschmeding waar ik mijn eerste piano heb gekocht net zoals mijn vader zijn piano daar had gekocht) Wat een vakmensen daar bij Clavis. Ik heb in 2016 mijn stemprogramma bij Dirk gekocht en ik geniet nog steeds van dat programma. Wat geweldig zuiver kan ik mijn vleugel daarmee stemmen en gestemd houden. Niet meer wachten op mijn stembeurt. Ik doe 2x per jaar een precisiestemming en tussendoor wanneer ik dat nodig vind een beetje bijstemmen. Heerlijk om je instrument in topconditie te houden en een genot om op een lekker zuiver instrument te spelen met dank aan Dirk.

I use the Dirk's Piano Tuner since 2014 on my Baby Grand Clement Piano. Tuning now is a really simple and fast task I can do by myself. Thank you Dirk for this great tool!

Very good program, very easy to use and very good stretching calculation. Of course a few bass strings, the most difficult to be tuned, need some adjustments by ear finding the best compromise between octaves, thirds and sixth but most of them are already ok from the calculation. [Dirk: There still is something not ok; all strings have to be optimal after tuning]

Dirk's Piano Tuner ist echt zu empfehlen !!!
Weiterhin ist der Support top, und wie ich meine einzigartig, was die Antwortzeit und Kompetenz betrifft. Würde 5 von 5 Sternen vergeben. Danke Dirk.

Als liefhebber/restaurateur van mijn oude klassiekers in de pianowereld (Erard, Broadwood, Bechstein en Steinway) ben ik een uiterst tevreden gebruiker van Dirk's-stemsoftware. Het is dan ook een kleine ramp als je laptop sneuvelt. Niet bij Dirk. De volgende dag kon ik weer stemmen! Bedankt voor de prima service.

I have had 2 university piano technicians check my piano (7' Baldwin SF10) after tuning with your program. One said "Do you want a job?", and the other said "I'm glad you already have a job, because you could put me out of business!"

I can hear beats and tune unisons and octaves by ear, but it is so much easier being able to use your program. I even use ear plugs while tuning and just use the meter. I usually start in the middle section and go down, tune the middle string of trichords, one string of bichords, and the single bass strings. Then start in the middle and tune the middle string going up. Then start in the middle going down and tune the other strings of each note, then the other strings from the middle to the top. It's almost like a pitch raise, and seems like it might be more trouble, but I think it helps keep previously-tuned strings from getting pulled out of tune.

Then I check every note by ear (without earplugs!) with all strings sounding to make sure there are no beats. I might have to re-adjust 3 or 4 notes at most, and continue to use the meter to decide which string is out. I don't do a bunch of checking with 4ths, 5ths, etc., but just trust your program to take care of that.

The first tuning took around 5 hours because I had to learn how to use a tuning hammer. To me, the 2 main secrets are to make sure the string is lowered or relaxed into pitch rather than pulled up and stopping; and also make sure to hit the note pretty hard occasionally to make sure the tension is even in the whole string. After tuning about 10 pianos - some of friends - I am down to 2-3 hours. A professional tuner is usually faster, but I get a lot of satisfaction knowing I can tune my own piano.

Thanks Dirk! -Jim

Habe den Klavierstimmer vor 5 Jahren gekauft und jetzt den Computer gewechselt. Dirk hat sofort reagiert und meiner Bitte entsprochen, die Software auf dem neuen Laptop zur Verfügung zu stellen. Super Service und ein Super Programm!! Danke
