This may be a silly question, but can weather affect the sound/tone of a DP? Or can age affect it? It just seems that lately with the cold weather especially my Roland KR-7 has a more harsh tone. It's never had a very warm mellow tone like a Yamaha Clavinova, but it seems to have a louder brighter tone now, and sometimes one note when played will ring out much louder than others, even though I'm not striking it any harder. Can this be fixed or adjusted? Thanks. smile

Huh? Yamaha is typically the brighter sound sample which threw me off. I'll start with the obvious. Try your "brilliance" control if it sounds too bright. Or maybe some of your other settings are off. The KR-7 has a lot of buttons - did someone young and curious have access to it?

How cold does it get where the DP is?

If you're experiencing uneven response, you could have an issue with sensors or contacts. A good cleaning remedies most of this type of issue.

On the more subtle of possibilities, cool dry air responds different acoustically than warm humid air. The seasonal change (turning on the heat) may have dried out your air and makes the sound also "drier" than usual. Some people find this more perceptible than others, but I'd start by making sure the sound settings were explored for your taste.

One note ringing our louder than expected sounds like a possible issue with your sensors. They are little rubber things and in principle can get dirty or otherwise messed up. I wonder if temperature could affect the properties of the rubber in some way that matters...seems unlikely.

As for the sound changing with the temperature or age, no. The digital sound coming out of your piano does not change with the weather. I can imagine speakers, the air between the speakers and your ear, and your playing changing with the weather, but not the electrical signal coming out of the piano. Also your perception of the sound may be affected by how your body is feeling.

How cold is your house?

I'm with gv on that. I noticed long ago that sound is harsher when I'm cold, and mellower when I'm warm. So the weather conditions might be affecting you rather than the piano.

It's just a guess, but could this have something to do with the speaker cones being stiffer when cold?

Okay, thanks, will try to check my sensors somehow. Sometimes one note will play so much louder than the others it startles me. My friend who has a Clavinova said she noticed it playing my Roland, too. Yes, haven't been able to heat my house as much this year, so it's chillier than usual.

Is it always the same note acting up?

There's a youtube video of a dude fixing his piano by swapping the sensor from a never used key (like the top one) into the place of a key where the sensor had gone bad.

I'm not sure exactly how it works, but there's a little rubber button that gets pressed down and it has two sensors or triggers on it. It calculates the time between them to get the speed. If the rubber gets torn, they go through at the same time or something and it comes out super loud.

I tend to think the changed sound and the unexpected loud notes are separate issues.

I have the same feeling with the hi-fi system that is at the home of my mother. I only can listen to music with this system once a week. In winter, that room is cold due to nobody stays there, and I feel the sound from the speakers becomes a bit harsher or brighter.

I’ve measured the sound with pink noise, and these measurements are identical as in winter as in summer. Therefore, it’s all in my mind, at least in my case.

In my small apartment in winter, the humidity and temperature changes very quickly when I hang up my washing or do some cooking. The sound of my DP (via headphones) never changes.

I suspect that if I had an acoustic, not only will the sound change, the keys will probably start sticking too.

If a single note is hard to control, particularly if the same physical key gives you trouble after you transpose the voice a semitone or two, then I'd say it's a sensor issue.

If you transpose the voice and it follows the note rather than the key playing the note then it's probably a speaker issue. Foam and rubber surrounds can rot, spiders can stray from their spring constants, cones can droop, etc.

Here it is 2012, and now I am having the same problem with that loud note coming from the G a fourth below low C (at the bottom of the bass staff).
I believe it is most definitely the sensor. How much do you think it would cost here in the San Francisco Bay Area to have a technician come to my home to take care of this single sensor. Or is there an easy way to open the piano so I can get to that sensor myself? Would appreciate any suggestions you might have.

weather affects the air where sounds travel hence as well as your ears but electronic generators of DP are not affected.
