Hi Jeannie, >I was hoping to find a place for Q&A in the journal, so I hope this doesnt >waste to much of your time but I've got a Kawai studio with one note (5 >below the treble break), that has o.k. attack, but no decay and short >sustain. One of the most common causes of this malady is loose bridge pins, and bridge related problems. Loose pins will rob the note of a lot of energy, create false beats, and some times can add some very stange metallic noises. Tap the top of the pin with a hammer shank or pin set punch, also make sure the string is seated nicely to the bridge, and note the change. In extreme cases, I will pull the pin, work in some 5min epoxy or medium viscosity CA glue, reinstall the pin. I'm surprised at the improvement every time. A badly grooved or pitted pressure bar can give similar symptoms. Use a very blunt screw driver to move the string over and check for an improvement. It could also be as simple as a wood chip trapped between the strings and the bridge notch. Regards Roger Only one note has this sounding problem. Termination points seem >fine. It sounds almost like a frequency fighting with the plate or >something. I have had this problem before on a different studio piano and >have not solved the problem. Any ideas would be greatly appreciated.
