Hi Guys,

This one has been bothering me for a few months and figured I'd ask if anyone else is experiencing it.

If I play Japanese Grand patches and hit a middle C, I often hear a high pitch noise. The most clear way I've found to make it happen is if I play the Japanese Dark Grand patch and repetitively hit middle C and another key at eighth note or faster speeds while sustaining.

I have the original Kronos 61 with 3.1.2. I both tried downgrading the OS and reloading the original factory settings and neither helped. I seem to recall playing this patch in the past and not hearing this noise. I'm starting to wonder if something is going bad in the Kronos, but everything else seems normal when playing the board.

Has anyone else noticed this before?

if its a new problem, my guess its your keybed or the actual key.

Are u referring to C4 ? I have the 88; C4/Japanese grand has a bit of a clank.

I don't have that noise type- does it show up in recordings ?

Hi Greg, thanks for the response.

Yea, the keybed was the first thing I thought it could be too, so I played the note on an external MIDI controller and unfortunately still had the problem. I did mean C4 when I said middle C.

Here is a link to a quick sample with the noise: https://soundcloud.com/karls-6/japanese-grand-noise

Playing it today, it sounds a little more like digital noise than it did when I experimented a few days ago. It even sounds close enough to a high hat that I spent a few seconds making sure some drum sound was not getting linked.

Another thought I had was that somehow a piano sample became corrupt. So, I went through the piano types in the SGX engine and I could make the noise in most the Japanese Grand piano types but not German or Berlin pianos. Also, for some reason it was a lot harder to both make and hear the sound in brighter Japanese Grand piano types.

This is definitely a strange one as like I mentioned earlier everything else I do with the board seems perfectly fine.

I heard that annoying noise at 10 seconds. I am stumped. If no one else has suggestions , I think its a service center visit.

I heard the noise too. Sounds like one of the samples may be corrupt - probably only on one sample layer, so you only hear it occasionally. The brighter Japanese grands probably condense some of the sample layers over a narrower velocity range, which would explain why it's harder to get the suspect sample on these.
I would suggest reloading the factory KSC files from the DVD or via USB.

Hi karlos:

I listened to the patch through headphones, studio monitors, and an amp and can't duplicate the noise. I have and X88. I agree with mikelees, it may be a sample that's corrupt. Did you try loading just that sound somewhere to listen to it? I'm hearing more of a distortion vs. a high pitched sound, so that's why I tend to think it may be that. Let us know.

Thanks for all your responses,

Working off the given advise that it might be a sample that is corrupt I started playing with the EXs7 (Japanese Piano) samples in HD-1. I was able to reduce the noise down to being in 2 separate samples: Piano2.jp main2-L and Piano2.jp main2 strch-L

I definitely agree that it is more of a distortion noise and now that it is played through HD-1 I can hear it every time I hit the C4 (and only the C4). I tried loading the samples from multiple copies of the factory KSC files, and tried loading both to RAM and from virtual memory. All resulted in the distorted sample noise.

I'm not sure where to go from here but I'll continue to experiment for a while to see if it comes down to a setting.
