dougsuz Posted December 31, 2016 Share Posted December 31, 2016 Our recently purchased CDP 230R is out of tune with itself. The C is flat, the D is sharp. I know you can adjust the pitch for the entire piano, but what, if anything can we do since the piano is out of tune with itself? I thought one of the benefits of a digital piano is that it would always be in tune with itself. I need to figure out if we should return it and try a different model, or is this just a fluke?

Display Name Posted December 31, 2016 Share Posted December 31, 2016 Hi and welcome to the forums. Sounds like the temperament of your CDR got changed. See page EN-54 of the manual http://support.casio.com/storage/en/manual/pdf/EN/008/Web_CDP230-ES-1B_EN.pdf and change the tuning to EQUAL TEMPERAMENT.

dougsuz Posted December 31, 2016 Author Share Posted December 31, 2016 Thanks for that suggestion. We just did what you recommended, but it did not change anything. Any other suggestions? Quote Link to comment Share on other sites More sharing options...
Brad Saucier Posted December 31, 2016 Share Posted December 31, 2016 How far out of tune are they? Can we hear a recording of it? Quote Link to comment Share on other sites More sharing options...
dougsuz Posted January 1, 2017 Author Share Posted January 1, 2017 It's just slightly out of tune, mostly to a very well trained ear, but annoying nonetheless. Will try to post a recording on a day or 2. Quote Link to comment Share on other sites More sharing options...
Jokeyman123 Posted January 1, 2017 Share Posted January 1, 2017 Are those 2 notes in a specific octave, across all octaves of just a few octaves? This is a strange malfunction. and i would also like to hear it. Are the octaves in tune with each other? In other words, are these 2 pitches in tune with the other octave C and D pitches? There will always be some "beating" between octaves, even with the best acoustic pianos due to harmonics, variations in playing dynamics. I have almost never heard any digital with this kind of note-specific anomaly. Usually, digital keyboards use a "matrix" for scanning key presses and this is divided among groups of notes although I'm not sure how Casio does this. That is why I'm asking if this is only in one specific octave, or in all other octaves. This would suggest a possible electronic malfunction if it duplicates across more than one octave. Just 2 notes, very odd. Individual key sensors in these Casios and most others have no relation to pitch changes, only to dynamics, speed of keystrike and which sample is being triggered based upon depth and intensity of key strike (with the Casio tri-hammer action anyway). So the keyboard mechanism? I can't think this would be the source of the problem. Please post a musical recording. Quote Link to comment Share on other sites More sharing options...
dougsuz Posted January 2, 2017 Author Share Posted January 2, 2017 OK, so this is a little embarrassing. My daughter is the one with the great ear and she initially thought it was out of tune. But she then told me she is getting over a cold and maybe her hearing was affected, so we used a tuner to check it out. After doing so, it seems to be pretty darn close, especially when we compared it with a higher end piano. Thanks for your input and sorry to waste your time. I do appreciate your responses. 1 Quote Link to comment Share on other sites More sharing options...
Kellie Posted February 26, 2018 Share Posted February 26, 2018 I have a similar question!! I have a Casio CDP 200 and it goes out of tune WHILE PLAYING. Sounds like it's slowly dying!! It doesn't happen all the time but has happened during professional gigs and transposing, turning it off/on again doesn't work. What can I do!? If you need a recording I'll happily send one through!

Brad Saucier Posted February 26, 2018 Share Posted February 26, 2018 If it has a pitch bend wheel, run it up and down several times or more to self clean the electrical contacts inside of it. Let us know how that goes and we'll take it from there. 1 Quote Link to comment Share on other sites More sharing options...
