Ringing noise-CVP290

[Ian J. Evans]

I noticed a ringing sound in the following three notes at the low end of the keyboard.

Namely: F0, F#0 and G0, the lowest of those notes on the keyboard. This happened whenever the notes were played hard as in staccato, or just played loud and when the keys were bottomed out. If the notes were played very fast it was not noticeable.

None of the adjacent notes had this ringing sound, in fact they had very nice full and rich sounds.

I contacted my dealer who is a very helpful person and a musician also.

We discussed this problem at length and tried different volumes and touch, but the noise is still there except with a very light touch at full volume.

I changed the Brilliance setting to DARK, at his suggestion, and saved the setting in the USER drive of the CVP. At this setting the ringing noise is definitely diminished, not entirely gone though at full volume.

My dealer suggested that it may be a function of the sample taken from the Yamaha grand piano, which may have had this ringing noise on those notes at that time.

If this is the case then one would expect that every CVP290 and possibly the CVP270's would all have this characteristic built in.

My question is to all you users with the same series pianos, have you noticed the ringing sound on those notes or any others for that matter...?

I look forward to your responses.

Ian, my CVP900 exhibits similar behavior, also a little on E0. It's noticeable in Grand Piano 1 and even more in Grand Piano 2 - seems to go up a few more notes. I suspect it's in the sample. I've listened to a few of my other sampled pianos from Gigastudio and most of them exhibit similar sounds in that range. Next time you have access to a good acoustic grand, see if you hear the same kinds of things.

I have a CVP209 and I noticed the ringing you describe on middle "C" on Grand Piano 1. The 2 notes to each side of middle "C" do not have this ringing. On Grand Piano 2 I notice the ringing on the "A" above middle "C". It use to bother me at first because I focused on it all the time, but now when I play I don't even notice it.

[ragvand]

To clarify what I said above. I don't hear the ringing when the note is played loudly as staccato, I hear it when you hit the note, keep the key pressed down and you let the note decay until silent. As the note is decaying I hear a continous ringing (almost electronic sounding) that I don't on the notes next to it. It's most noticible on middle "C" in Grand Piano 1, and on the "A" above middle "C" on Grand Piano 2.

Thanks for your replies folks.

It is interesting to hear that some others have strange sounds; however, there does not yet seem to be a consistency.

I was hoping to hear from more users as I think that there have been quite a few new purchasers of CVP's in the few months that I have been monitoring this forum. Perhaps we will get more responses yet.

Ragvand:

The ringing sound on my 209 is only at the low frequency end as I described, thank goodness not at middle C! You are correct about the problem of focusing on the sound, it is hard to ignore once you hear it.

Jim:

I do not understand the reference to Gigastudio, i imagined it was a music software program until your post, is it a music store...?

I will have to check out my piano teacher's small acoustic grand next lesson; however, I don't think it has as rich a bass sound as the Clavinova grand.

I don't notice much of a ringing sound at Grand Piano 2 but some of the other voices have it . It makes me wonder if there is some cross "polinization" (can't think of a better term right now) within the tone generator, of sounds causing the ringing...?

What do you mean by..."also a little on EO"...?

Let's hear it from you users, one way or another it is good to find out, one never knows Yamaha may also monitor this forum, and they should hear about these things.

Just re-read my original post and I see I got the CVP numbers messed up, sorry about that.

I am referring to the CVP 207/209 series...!

Ian, I would imagine the tone generators and samples in the top-of-the-line CVPs are identical. It may be that different people just have different sensitivities to the kinds of noises we're talking about.

Gigastudio is a sample player - it plays enormous samples off a computer hard disk. I have one connected to my CVP and have installed a number of sampled pianos (Bosendorfer, Steinway, Yamaha, etc.) I listened to them in the range you're talking about. Some have some degree of ringing in the very low range which I take as just the way the sampled piano sounded. Not objectionable, just part of the character of the instrument. The CVP piano is a little more pronounced, perhaps.

After 162 viewings of the original post and less than 2 % responses that have similar sounds riding on top of the notes, one must assume that these are rare instances.

I don't think that it is of any purpose to pursue this any further with Yamaha.

I am glad that in my own case these sounds are at the low register of the keyboard and notes that are seldom used.

Like many things in life one can gradually become accustomed to them and learn to ignore them. It is gratifying to know that there are so many satisfied CVP users and to feel that I made a good decision to buy one.

I have yet to try all the bells and whistles so I am sure that there will be lots of questions in the future. It's good to know that this forum exists to help.

hmm.. i guess the frequent viewings could be because of people checking back for answers, more than it being a problem for them....

Good point, it had not occurred to me.

As Jim noted in his post..."different people have different sensitivities" and maybe because my CVP is only a few weeks old i am listening for things. My old CLP did not have any extraneous sounds though, also it was from a different era.
