spidercan Posted May 13, 2015 Share Posted May 13, 2015 I bought a used px330 and I've been experiencing a buzzing/rattling noise on certain keys. It was specific to a single key at first, but it has become progressively worse and seems to have migrated to more different keys. It's less of an issue when I use non-piano tones. Is this an easy fix or should I try to return?Thanks Quote Link to comment Share on other sites More sharing options...
Joe Muscara Posted May 13, 2015 Share Posted May 13, 2015 Do you hear it with the volume turned down? Quote Link to comment Share on other sites More sharing options...
Display Name Posted May 13, 2015 Share Posted May 13, 2015 It sounds like the speakers are vibrating sympathetically with certain notes. My first guess (and this is just a guess) is you have a loose speaker that is getting looser the more it vibrates -- probably just a screw that needs to be buttoned down.

Jokeyman123 Posted May 13, 2015 Share Posted May 13, 2015 Right, we need to know if this is coming from the key's physical action, or from the sound samples. Either way, it seems like a malfunction. Since you say it is only happening with the acoustic pianos, there must be something happening with the internal sound samples. If there is a factory reset on the PX330, I'd try that.

Certain tones contain frequencies that will cause a loose speaker to rattle. We just had a case with the PX-5S and Spacestation Speaker where only the electric piano tones would cause vibration on the speaker. Also, note he said it is "less of an issue" with other tones, so it is still happening. The fact that it is getting progressively worse and happening with other keys is the big clue for me.... 1 Quote Link to comment Share on other sites More sharing options...
Jokeyman123 Posted May 14, 2015 Share Posted May 14, 2015 That may be true (I've taken mine apart and had to tighten the speskers internally and also added some aoustic damping material inside to alleviate the problem Scott has described. However.... forgot to ask something very important....Spidercan are you playing through headphones or the built-in speakers? Or are you playing through an external sound system? A little detail perhaps important! Quote Link to comment Share on other sites More sharing options...
noemie Posted November 25, 2023 Share Posted November 25, 2023 Hello, I have the same piano and sometimes the sound start to become weird, as if I was using the vibrato (kind of a water disturbed sound) it come and goes. Can anyone help ? Quote Link to comment Share on other sites More sharing options...
Brad Saucier Posted November 25, 2023 Share Posted November 25, 2023 Can you provide an audio clip? Like a picture is worthy a thousand words, so is an audio clip. That usually helps tremendously. Quote Link to comment Share on other sites More sharing options...
