Entropy-Piano-Tuner

[@anthony-s8l3d]

After using this software to tune my upright piano, it has never sounded better. It's almost as if after 40 years of owning this piano, I can now hear what it is really sounds like. The creators of this software have provided a great service in making this freely available. I thank them.

[@megkalapnemadom]

I tuned an upright piano with the Entropy-Piano-Tuner (in 2 days :)) which was disregarded since years, beacuse it was 1-1,5 note out of tune, down. The owner is now VERY pleased... and i am fascinated. Dear Entropy-Piano-Tuner Team, thank YOU for this useful tool! One should keep in mind, that if a note is more than half note out of tune, than the quality indicator wont work. Before tuning these notes, one should tune them roughly into range, than record the note again with inhamonicity detected (=>quality~good), than calculate, than "fine"-tune.

[@lrgalicia5598]

You comment is very usefull, very very usefull: "One should keep in mind, that if a note is more than half note out of tune, than the quality indicator wont work. Before tuning these notes, one should tune them roughly into range,.." Thanks a lot

I live in the centre of france where temperatures can soar to the middle 40s and plunge to minus 15. To enable my piano to stay in tune i would need to enlist the services of a tuner every 3 months. Yr software has been a lifesaver and i am extremely pleased with the result. Than you so much for dedicating your time and effort in creating this masterpiece!

[@peterherman2032]

I just recently acquired a tuning hammer to take care of a "sour octave" (which I did by ear) and then I stumbled upon this great App and gave it a try (only on lower 1/3 of my Petrof baby grand. WOW - what an awesome improvement it made in the sound of my piano - I wish I had recorded a "before and after", but the bass really sings beautifully now (although it had drifted rather sharp in bass register due to humidity, so this was a pretty easy test!). THANK YOU, SIR - you have my deepest respect and appreciation for this great idea/app/technology - I can't imagine why you are "giving it away for free", but hats off to you!

Very practical and useful program. So impressive to hear the results after I've carried out tuning!

[@Supersolyman]

I tuned my rhodes piano last weekend with this program. I was skeptical at first and every single note was registering as low quality. I had a USB condenser plugged in with the right level and gain set. This program just is not designed for those types of sine waves i guess. despite this I continued through and every note recorded first try no problem. Took me a few minutes to figure out how to configure 73 keys E to E. Tuning was straightforward and only took a few minutes to get the hang of. Even though i had little confidence following through, the result was a perfect tuning and the best tuning ive ever done. In the past I have tried tuning my Acoustic piano a few times with mixed results, but eventually got frustrated and hired a professional. Ive tried tuning my rhodes a few times before, with sligthly better results than acoustic tuning but still not perfect. With this program Im going to try my acoustic next.

[@JakeTheBoss-fp7lm]

Solomon Cowan but how did you tune the keys with 3 strings?

[@NathansHVAC]

Use a long mute strip and stuff it between all the outer strings. Make the entire piano single string on all the keys. Then run the software and just tune the center strings. The harmonics and partials are based on the string length. After the piano is perfectly tuned with the software, go back and tune all the outer strings one at a time by removing the beats. No need for software. Get the beats to less than 1 per second.

[@ElmaOrkestra]

Did you use built in mic or get an audio interfact t work? I cant get it to see an interface on the Mac OS version.

A lot of people tend to give their old piano's away for free here in my country. I told my mum about it and she said she'll think about getting one. Of course these piano's will be out of tune (Also stated in the adverts) so I'm just preparing of what might be coming my way. This will save us 75 euros a year. I get why it's high priced as it takes some time to tune a piano, but is still is pretty expensive. Thanks for the free software. I've looked through it already and it looks simple and straight forward. Thanks for the good tutorial!

[@b_a_fps1569]

Welp, my mum thinks it's best to lay off on the piano for another 8 months as I really need to focus on next years school. Halfway the schoolyear, we can see if I still have time to play with all the exams and stuff. :(((( I do get it, though.

After trying it, I will make an update. Can I help with a translation in Dutch ? Kind regards from the Netherlands. *update 11-11-2018*: i recorder my Grand Gors & Kallmann on my reguylar ASUS laptop without an external mic. This went easy. Then I tuned the piano to 440Hz and repeated it 1 time. I am so satisfied with the result and keep the recording and target for future tunings. Also my deep respect for making this and sharing this. Awesome.

Thank you for the software! It's working great, I'm tuning my parents piano (not done yet but it already sounds so much better).

[@johnb2832]

I cant say thank you enough. I have a Samick Baby Grand 5'9" that I play all the time. Sadly I have only "HAD" (not by me) it tuned once every year to 11/2 years. Which is way to long for me. It sounded terrible but I was tired of paying the $125 every time I had someone tune it. So I read everything I could to learn, and everything I could about tuning a piano. From pulling it (which I didnt need to do), to temperament, to partials, and so much more that I know have a deep respect for tuners that I didnt have. So before I actually learned how to tune I tried to tune everything to a 440 temperament and all the frequencies. Well you know how that sounded! In tune when playing one key but terrible as you would know playing a run or any other combination of keys. That is when I knew there was soooo much more. I was about to give up and call the tuner. After studying all about tuning, I found your program and loaded it into my phone and tried to tune that, of course as you say its for testing only on a phone. So I bought the Scarlet 2i2 Studio set $249(Condenser Mic., headphones and everything to hook it up to my computer) and plugged it into my Mac and that made all the difference. My piano sounds beautiful. This was my first piano tuning that I did right and I just wanted to thank you soooo much for this program. I can now tune my piano ANYTIME I want, without paying $500 a year for tuning. Yeah the Mic was $249 and about $100 in tuning materials but I wont have to pay another tuner again!! You should be compensated for this program. It works great!

[@joseadrianvaldes9792]

Hi, I'm trying to learn how to tune pianos myself, until now I have learned some things about inharmonicity and technique, what are the most important things I should learn?

[@handyatmusic]

This program has some powerful features. I am especially impressed with the spectrum tuning display which shows you what all 10 partials are doing at the same time. If this program actually produced an even, decent sounding tuning (which it does not in my experience), one with a smooth tuning curve, rather than one that sounds uneven especially in the bass and across the break, and generally sounds (and looks) amateurish, it could potentially compete with professional tuning software and hardware packages that cost up to a thousand dollars or more. I would also question why it is necessary to sample all 88 notes when other hardware and software products (again, professional and usually costing a lot of money) take representative samples from different regions of the keyboard and successfully extrapolate a good tuning for the whole piano. This is very time consuming, and when it is one's livelihood time is money.

[@lindafuria2889]

yes, this software does has some amazing features, by sampling every note it is possible to get a good interactive tuning rather than the other ETD's, which only samples a few notes. Of course at this early stage, Entropy isn't meant for the piano technician tuning to make a living-maybe in the not so distant future hopefully it will fast enough to do quicker tunings...

[@IsaacOLEG]

thanks for providing that interesting software. if the piano playing in the background is tuned with your software, the tuning (sound in tune indeed) have some sort of much articulated tone, a little as what is obtained with Dirk tuner, a may be similar program (too compact may be, in mediums, while articulation and clarity of tone is sort of proof of the success of computation, I think). (also possibly the human ear wish to hear some stretching, hence the good results with some options as 12th 15th balance) I have trouble defining where the difference is if compared with human tuning, I like to put a finger on that, as tuners (some) really use those power peaks created by harmonious mix of partials in octaves and other slow intervals. may be the fact that the tuner listen very early to the tone to catch that "minimal entropy' is where the resulting difference hide (I feel that softwares are yet slow when it comes to 'listening'. I hope there will be more studies and may be other algorithms or other options, this is a fascinating subject. Regards

Hi, great softW. I think it is amazing. I have questions: I understand that we have to mute strings and leave just one. How about the high octaves, do we have to do it?. 2) How does the softW consider the fact that pianos are tuned using intervals and beats? Thanks...

[@theproject9577]

Always tune to the middle string. Numb the two outside strings of the three strings of that note ,leaving the middle string still open. Make sure that one is tune then un-numb the two outside strings one at a time and synce them up one at a time. You'll know when you got it right they will all together sound like one string being played.

[@elic307]

When you get to a note that has more than one string, which one of them do you tune (others are muted obviously). Should you repeat for the previously muted strings unmuted?

[@MrGabrielcito]

Per the user manual: "For unisons (keys with several strings) we recommend to tune only one of them with the EPT (while muting the others) and then to adjust the other strings aurally."

[@josvanr]

What does it mean when the strobe patterns in different bands move in opposite directions? which one has to be stabilized? thnx

[@josvanr]

PS this especially happens in the higher pitches. Eg the lowest pattern is moving to the right, and the pattern above that one is moving to the left. Should I stabilize the lowest patter, or should the entirety of all patterns be as slow moving as possible?.. (like average speed as small as possible)

Thanks for this great programme! What do I do when the green tick doesn't align with the key that was pressed in the Record mode? The green tick on the screen is always one key before the one I actually pressed. Wouldn't that mess things up when it comes time to tune the keys?

[@klankenvanger]

You should first determine what causes the software picking the wrong note. The first thing you want to do is to determine what frequency A4 is set at. For example, if A4 from your piano has a frequency of 432 Hz and the software is set to A4=440Hz, then things will mess up since they don't match. Once you know that A4 of your piano matches the values of the software, it should be fine. If it doesn't, then it means that your piano is severe out of tune. You can turn on 'forced key recognition' in the software, but that should only be done with single out of tune keys. If the software keeps misjudging the key recognition, you should probably go for a pitch raise. I hope this will help. Kind regards, Peter

[@happysteele]

@@klankenvanger Thank you for your kind suggestion Peter. Can you please recommend a good frequency analyser app to measure the frequency of A4?

[@klankenvanger]

@@happysteele 'Tuner Pitched' for Android or 'Pitched Tuner' for IOS should do the job for you. There are countless of these sort of apps available and basically they all work the same. Once you have completed recording all 88 keys you'll have a prophile of that specific piano which you'll have to save on your computer. You can then switch to the 'tune'-tab where you'll be able to see the measured frequency of the keys you'll press. So when you have one prophile available, you won't necessarily need an app anymore. But having an app can always help as some sort of reference/security. Hope this helps for you! Peter

[@klankenvanger]

Oh one more thing: if A4 of your piano is way lower than 440Hz (like for example 430Hz), don't raise it up to 440Hz in one session since the chance of breaking strings increases: the difference in tension becomes too big. In the option menu (file/new/options) of the Entropy software you can fill in the desired concert pitch. Keep it at 430Hz (no problem as long as you don't play together with other instruments) or raise it a little (voor example to 434Hz). After a few months you can choose to tune it again and raise it for another few Hz. In this way it takes a few sessions but it's better for your piano and the tuning will hold much better since your instrument gets time to adjust to the new string tension. A pitch raise is quite a painfull experience for your piano, so you better not rush it. Regards, Peter

@@anthonyb2745 I also would say equal, as the SW tries to match globally the tuning, which means no specific interval or key is favored. That said the SW developers claim they do not know which Temperament is it closer to. Maybe we could call it Entropic Temperament/EnT?

I'm not sure if it's the computer I am using but the setup of the Entropy Piano Tuner looks a little different from the one you are using.

2:22 but which string do you mute exactly? expecially on the keys with 3 strings on it ... And after calculation and tuning "the one" string, do i have to repeat the whole recording / calculation / tune process for the others strings as well ?

[@thepubliceye263]

I don't think it matters which string is muted; it's just to stop multiple inputs from different strings; so just pick one to mute. Once the isolated string has been tuned to the correct note, then I guess you can move on to the next string of that key and tune it to the same pitch (while muting the other), and same principle if there are three strings. I've not tried to the software myself but I think this is the logical conclusion.

[@lindafuria2889]

Paul, if you are new at this I would advise you to apprentice with a professional piano tuner at least for a few hours to learn how to tune unisons. Unisons are usually tuned aurally, especially in the bass section. It takes a few hours to learn how to equalize the tension on the strings so that the pitch will last for a while-this requires a good tuning hammer technique which is best acquired from a pro..

[@waynetaylor7086]

[@Xenthera]

I used this app to tune my kawai ge-1. It needed a pitch shift as well. Not only does it sound beautiful but I also learned a lot as well. I've read so many comments of people swearing up and down that you can't tune your own piano, and while I agree it takes patience and a soft touch it is possible. I can already hear the elitists claiming "Ah well you may have tuned it but it will never hold its tune only a professional can do that!" while that may be true for some pianos, my tuning (after I did a fine tuning) has lasted 3 weeks so far. The only thing is my ipad's mic was not really up to the job so I moved to my macbook with a dedicated mic.

How did you solve this problem? If a key is lowered by more than a half a tone, entropy will detect for example a C as an B. Do you have to adjust the Hz pitch in advance so entropy will adjust to the situation?

Same issue here. Ive given up.

[@johnb2832]

I know its been a year but someone else might have this issue and this will help them. You need to go into your settings on your mac and then the "sound" Icon, then change your input and output setting(CHANGE BOTH) which turns your speakers and mic off and lets the interface do the work. But make sure you plug everything in first so your mac will recognize it and you will be able to change the settings then. You will also need to change it on the Entropy program setting too. Go to "Entropy Piano Tuner" upper left in the program then "preferences" and hit the speaker icon that says "Audio" on the left and then "Device" Change that setting to what every your interface is named. There you have it. Hope it helps.

I have one question: for multiple strings for note, when we record we have to record all the strings separately. and when we tune we do the same as the record part? I apologise for my bad english(if it's bad) but english is not my primary language. Michele from Italy

[@bluestreak711]

I am under the impression we only record one string for each note and when we begin tuning, we tune all the strings within that one note in unison. Your English is fine. No one would have noticed English was not your primary language if you would not have pointed it out.

[@NicolasHeine]

I don't really understand why we need to record all piano keys first and what this algorithm is calculating there. Isn't a correct tone always at the same pitch, no matter where the detuned piano is coming from?

[@brennansmith3892]

[@mariussiuram]

piano-tuner.org/entropy tl,dr; Using an Equally Tempered scale (what you call "a correct tone" which is not accurate and does not exist per se) results in inharmonicity. Entropy-based tuner addresses that.

[@NicolasHeine]

I am familiar with the tempered scale and that it is not perfectly harmonic. However we use it and accept it. The tempered scale is dividing the octave into 12 equally big semitones. Those frequencies should be the same, no matter where the piano is coming from. So still I don't understand why I have to record all tones before tuning and what this algorithm is really calculating...

[@mariussiuram]

@@NicolasHeine If you know all that and are interested in more details of piano tuning, you can go to the link I posted, or read the EPT manual. Note that "correct tune" of a note and "correct tune" of a piano string is not the same, when considering the standard tuning curves for pianos that make bass notes flat and treble notes sharp due to the string/rod harmonic deformation (I forgot the proper term for it, but I hope that you understand what I am referring to). And piano aural tuners always take the whole piano --which is the point of a software such as EPT.

[@marcan42]

Of course, if you want to play a piano with near zero inharmonicity and perfectly tuned keys, the solution is simple: get a piano modeling software synth and build yourself a virtual piano with 10-meter long strings :-) Kind of hard to realize practically, but it sounds really nice!

I have downloaded Entropy but it will only recognise the first two notes on the piano. What is the problem? I'm using an iPad to record with.

[@Mikas_Emil]

maybe they are too far out of tune. Maybe you could use a standard tuner to get them a little closer before you record the notes in entropy

[@momo_the_duck]

I have 85 keys on my piano and I don't know how to set "key number of A" and "keys on bass bridge". Can anyone help me?

[@christophwick832]

Just subtract how many keys are missing in the bass section: A 88 key piano starts with an A. The layout in virtual piano should then match your piano's.

en 5:24 se muestra una sinusoide para poder afinar, a mi me aparece una imagen difusa de colores similar a un holograma que se ve negra si la frecuencia se acerca al "pitch" óptimo, me resulta imposible afinar de esa manera, no se sabe si subir o bajar el tono, me pregunto si no funciona mi soft descargado, es otra versión, o quedó mal grabado el piano? lo muy positivo de la app es que permita guardar las grabaciones, dirk's piano tuner se borra todo si se apaga o se cuelga la PC, o sea que es solo perdida de tiempo. muchas gracias

[@ariellopez2224]

+boris6145 a mi me pasaba igual pero haciendo click sobre ese recuadro cambia de los colores a la sinusoide

[@berntd]

Is the site down or discontinued?

[@christophwick832]

The page was moved to piano-tuner.org

[@berntd]

+Christoph Wick Thanks. I found it.

[@randypcole]

Brilliant.

[@oofeeleelee6556]

How can I adjust it for a piano tuned down half a step

[@globefm]

At 1:05 is described to adjust the frequency

I wonder what microphone are you using to record the notes in the piano. There are 2 keys that are clearly out of tune in my piano and I wanted to fix them. Sadly I don't want to break the bank is a professional microphone. Do you know of an inexpensive microphone that does a good job? I figure an improvement over my laptop pinhole microphone might be worth doing. Although, I really didn't want to spend much more than $20 or so. I wonder if I ask for too much.

[@rreexx]

+Car Cas, Hi! I'm testing the EPT recording my piano with a SAMSON C03U USB Condenser microphone and works great!. See it here: www.samsontech.com/samson/products/microphones/usb-microphones/c03u/

[@anthonyb2745]

If it’s two keys, do it by ear

[@harisbakirtzidis9805]

i have a problem.i go all the way but when i try to use the tuner of the software,i hear the tones from the keyboard on the program and so i can t tune my piano!!!!does anyone knows how to solve this.i guess i m doing something wrong.thanks

[@leodellapietra]

there's the icon of a loudspeaker. Clicking it will mute the echo sound

[@alexuturgaidze5722]

I can't run the soft with an external sound card.

[@ElmaOrkestra]

Anyone having an issue where their audio interace wont show up? Im only seeing built-in mic. Im running Mac with UAD Apollo with thunderbolt but Ive also tried a Focusrite 18i20 USB. Both wont appear!?

[@vrsemurphy]

Hi there-I was just wondering if you ever had any luck getting the UAD up and running on your Mac with this software? I have a 2018 Mac mini, a 2012 MacBook Air, both running Mohave, and a UAD Apollo Twin MKII and Entropy recognizes the interface within the software but the mic doesn’t register in the idle mode or record mode(although it’s picking up the signal). Using the built-in mic on the MacBook Air works but I was really hoping to use my nice mic?!

[@ElmaOrkestra]

@@vrsemurphy Hey, no it was a while ago but pretty sure I gave up and didn't get it working.

[@10gaugesbelow]

what do i do if im not happy with the calculation? iv tryed making it recalculate and it calculates it the same every time. its no good. my solution was to record a grand piano off of a keyboard and use the restore to orginial tuning function to tune an actual piano.

[@philgrant8927]

I just fine tuned my Baldwin 5'8" grand by using Pano Tuner free software to compare with two virtual pianos that I have. One was the Bösendorfer and the other a Steinway. The free software gives you the exact frequency to the first decimal place so I just tuned it exactly to the virtual piano (the Bösendorfer; I just compared with the Steinway, which did not have quite as much stretch). That software is useful because it's very difficult in the deep bass and high treble to hear the precise pitch. But it is not a precise way to tune because of 5'8" grand will receive a different tuning than a concert grand. The book I have on tuning says that, for example, the intervals of fourths and fifths may be more narrow. So I was hoping entropy would help that. I appreciate your comment because I was going to redo it with entropy but it seems it may be a waste of time and just make it worse. Perhaps I will try the entropy but test on my electronic keyboard before I tune the piano. Not sure if entropy actually deals with stretch tuning.

[@bluestreak711]

My phone does not seem to run it efficiently because it does not have enough power and the application malfunctions on Windows 10. From what I could use on my phone, it does look like a great program, but I would really like to have Windows 10 support (Since Microsoft forced the update on us all).

[@bluestreak711]

I just took a Windows 8.1 computer I had out of storage and I am having the same problem. The sound going through the program is severely distorted. Assuming that it may not effect the tuning process, I went through with it anyway, but it was giving me off the wall readings wanting me to take the piano further out of tune. With the fourth octave almost perfect, I tested out the program and it wanted me to change the notes drastically in different directions.

[@christophwick832]

This is known problem with the EPT software that only occurs on windows. You can change the buffer size in the output settings (e.g. double the value) as a workaround.

[@bluestreak711]

The default buffer size is 50. Should set it to 100? Could I set the buffer size larger? Will I be able to use this software effectively on Windows?

[@christophwick832]

This value defines the buffer size for the sound in milliseconds. A larger value will increase the delay between 'keypress' and 'output'. I suggest any value between '50 and 2000'. To your last question: Are there any further problems with the software besides the distorted sound?

[@Supersolyman]

I ran it on a windows 10 laptop no problem.

[@jacolon61]

I was tuning my piano last night and it crashed on me. The file was not saved although I entered the information. So I have to go back, record all the keys again to get back and finish my piano. Can anyone tell me if I did anything wrong?

[@christophwick832]

The file will not be saved automatically. You have to press the 'save' button in the toolbar to save the file.

[@jacolon61]

Yes sir. Got it, thank you!

[@NiclasEklow]

I hope it was the program and not your piano that crashed! :)

[@respekt200]

Tried with Android - record just A0(key became green) and then. nothing else let me to record... That was the end of it. :) Yes it was showing like it's recording, but in the end it said "not all the notes recorded" so couldn't tune.......

[@dampfnudel6801]

You didn't set it up correctly, dude

[@ThePoshPleb]

Ideal for someone with plenty of time on their hands but not so good for a tuner that needs to earn money.

[@ВадимАрхипов-в6й]

Сделайте перевод этого ролика на русский.

[@donprior9144]

this might be a great aid to some but by the time you calculate each not I would have had the piano almost tuned. Any good tuner doesn't need this device.

[@GuillermoSanchez-db1lm]

the best piano tuning is aural pianotuning.

[@gary66992]

No best method is to pluck each string ABCDEFG till tuned bang on

[@michman_k-14]

А как Вы это себе иначе представляете?

[@ricaramurica2260]

Entropy Piano Tuner is no good for my piano The soft show the frequence who must to have the note of the piano, not the frequence real of the note of the piano.

[@ijabbs143]

a pain in the butt.. so many easy aps out there

[@marioburgess3526]

play me middle c

[@ScaramouchedaVinci]

A good idea. But I am not satisfied with the result. It doesnt really sounds in tune. The TLA CTL 5 is much better.

[@Cadw]

I'm just not interested!
