Hello,

I have a Clavinova CLP-220 which for some reason is playing significantly too high (approx +47% according to tuning software). Honestly I am no musician, my wife is, and she is distressed because of this.

I tried the procedure from the user manual - to tune down, hold A1 and A1# and press any key between C3 and B3. I tried repeatedly pressing the key between C3 and B3 while holding A1 and A1# ; I also tried repeatedly pressing all three. None of this has made any difference. Meanwhile transposing works, so it seems that keyboard control in general does work.

Is there any way I can change the pitch of this piano? Apart, of course, from using it as a MIDI source with a separate synth, which is not a cheap option.

I would be very thankful for a solution!

Yours, Mikhail Ramendik

After much more googling I found a solution to the problem. The keys to press are not A1 and A1# but the two or three LETMOST keys on the keyboard, which the manual, confusingly, names A-1 and A#-1.

I hope this thread can stay on the Forum so that those running into the same problem could find it by googling.

I would suspect the tuning software. It's extremely unlikely that any Clavinova plays 47% sharp, esp. after re-setting it - they shouldn't even be able do that when they go seriously wrong. If you think that you're software is right, call Steve Marsden at Yamaha on 01908 366700.

After the reset it plays correctly. My problem was that I misunderstood which keys to press to reset.

So which bit of the promo literature did this come from? Cutting and pasting from corporate literature and publishing it usually involves some sort of copyright infringement, so I'd be a bit more careful.

With regard to digital pianos these days, it's impossible for a digital piano to out of tune with itself (i.e. you don't get the odd key out of tune with the rest of them - unless you've played around with some sort of micro-tuning facility). In any case, resetting a digital piano to factory settings should always get you back to A440.

It's like a computer generated response isn't it!

Yep.
