My Yamaha p140 is out of tune!?!

I have a Yamaha p140, and several of the notes have gone out of tune! Aflat and e-flat are now out by nearly a quarter pitch. I didn't think this was possible.

We do have a child who like to push buttons on the keyboard; is it possible he managed to "de-tune" the intervals some how? Is it possible to re-set the tuning?

turn off your keyboard and turn it on again while pressing c7 (last key on your piano)

Same problem happened and that fixed it

Technics SX-PX662 also out of tune
by: Rob

... and turning off and then on holding down highest key on the keyboard didn't make a difference. The piano's in tune with itself, but the whole thing is about half a tone sharp. Much obliged for any help folks can give me.

YPG-635 Out of tune also
by: Anonymous

I have the same problem with my YPG-635. The notes become progressively out of tune. If you play a key in the first octave and play the same note in the seventh octave, the notes become flatter. At first I thought maybe it was me, but I've tested it with a tuner and it verifies this problem. I've talked to some people about it and it sounds like it has to be something wrong with the firmware. I mean, it's not like there's anything physically vibrating that's come out of tune. The tones are all synthesized digitally. I've also tried do the reset trick by holding down the key(s) and turning on the piano, but it did fix the problem.

I meant to say in the last sentence that resetting did *not* fix the problem.

P140 out of tune
by: jrp

Thank you LLR. The yamaha p140 was sharp and I did what you suggested and it worked. Hooray! Praise the Lord! Thought we would have to pay bucks out to fix or replace the keyboard.

my little world returns to normal
by: Roger in MA

Yes! Holding down c7 while turning on the piano worked! The message was "clr".

I had the same problem with the key of Eb and Ab that others reported.

Thanks so much for the very simple fix!

Worked for me too!
by: Pommy1

Our DGX-205 had the same problem --- half a note sharp across the keyboard. We thought we were up for the cost of expensive repairs or a new keyboard. Pressing C7 and turning the keyboard on and off worked brilliantly. I don't know how we would have fixed the problem without the Internet!

Yamaha P140 out of tune
by: Mike G

I own a P140 myself and half note sharp across the whole keyboard sounds ilke you have (accidentally maybe) hit the 'Transpose' button?! This will raise or lower the pitch of the instrument in semitones increments, allowing to play in a different key to what you're actually playing. This is quite normal and nothing to worry about.

Digital pianos do not normally go out of tune ever, or need tuning like real acoustic pianos. The pitch is controlled electronically by the P140's processors and on-board software. If somehow you do accidentally find the piano appears to be 'out of tune' then the best thing is to perform a factory reset, as mentioned already. This usually sorts most problems. Of course, faults do occur now and then, but Yamaha is known for good reliability.

If you don't have a user guide you can download one in PDF format from Yamaha's user guide website, just search in Google for it.

Hope this helps.

E-flat and a-flat out of tune. Now fixed!

Does not work
by: Anonymous

I have an Ensoniq SD-1 with the same problem, though the C7 trick did not work. When I start the keyboard it always says "Calibrating Keyboard - Do not touch", so when I do hold down the C7 key, it says "Calibrating Error" and I can chose from recalibrate and Ignore. I've tried both options but it does not work. Help please!

Tuning Technics SX-PX662
by: Gabe

I had a pitch problem with my piano and was afraid that the electronics were just shot. Thank God for the manual though! If you just press "Demo" and "Mode set" at the same time it will give you the option to change the pitch of the instrument. To set it to the standard pitch, just use the "Tempo" arrows to get the number to 40.00. Once you're finished just press either "demo" or "mode set" and enjoy!

P-200 master tuning
by: Anonymous

1/4 step #, retuned all other instruments to keyboard for one performance. Happy to find Gabe's post about 'master tune'. On Yamaha P-200, , , then slide to adjust to 440. Saved!

Thank you, Gabe!
by: Rob

It's exactly two years since I first came to this page trying to figure out how to get my Technics piano back at the right pitch. I wasn't able to find the manual. I was continuously frustrated seeing the "C7" solution, which of course doesn't work on the Technics. I finally gave up on the site, and only only yesterday noticed Gabe's "Demo/Mode Set" solution! And what do you know . . . I'm back in tune! Two years! Dug further in the piano bench, too, and finally found the manual. I swear it hadn't been there before. Rifled through it and found the same solution.

Still trying to decide what lesson to learn from all this.

Set Pitch to g#:Yamaha PSR 172
by: Anonymous

Hi,

I'll be grateful if any of you can tell me how to set the pitch on PSR 172 to G#. I'm aware that Transpose is to be used. I'm looking for the number that should be used for G#

Thanks for your help.

Simple Fix!
by: Anonymous

My Yamaha P-140 was flat to A440 AND was not in tune with itself - octaves were out of tune. Turned the keyboard off & then on again while holding down c7; the screen indicated CLr for clear. Turned it off & on again to clear the clear message & tested it. Worked fantastically well; so fast & easy! PHEW!!!!!

Note for newbies: c7 is the last key on board at the top(high) end of the keyboard

YPG-635 works
by: Anonymous

My son has the "ear" and said it was off by half a note across the whole keyboard. Held C7 while turning on, get a clear message, and it's fixed. Didn't have to hold while turning off as I had forgotten that part and it still worked! Very happy about this posting. Surprised there is absolutely nothing to be found on this in the owner's manual whatsoever..

How to fine tune DGX 230?
by: sologuitar

Please help. I just found out that the A key on my Yamaha DGX 230 does not sound correctly, it's lower than the G. Is there anyway I can fine tune it? The C7 trick above doesn't work for 230:-( Thanks a lot for your help.
