Hi folk. I have a fairly new ED 132 Seiler. I noticed early on that some pieces just didn't 'work' so well as other pieces on this piano, and it all comes down to the sustain: specifically, that when playing repeated notes or (especially) chords in slow-moving music, there was not a good sustain, even though the sustain pedal was fully depressed. This can be tested by depressing the pedal and then striking a note. The note produces its initial sound, and then there is quickly and suddenly a slight, but discernible, drop in the volume of that sound, even though it does continue to sustain. It makes it impossible to achieve the smooth effects that are needed in certain pieces.I wondered if there was something wrong with the design of the piano. But some notes seem to be okay, while others are not. The pedal mechanism is properly adjusted. Is it possible that this fault owes to some notes simply not striking the key properly? Yet, if I play one of these errant notes without using the pedal but holding down the key, there is no drop off in sound. The drop off occurs only when I'm depending on the pedal. I'd love to get some advice from the folk here.

Open the top of the piano, and look at the dampers as you press the pedal. Do they all clear the strings uniformly, especially the wedge felts in the bass?

Does it have a muting felt, which can come down between the hammers and strings when the middle pedal is depressed? Does the felt touch the strings when it is up?

Otherwise, I cannot think of anything that would cause this, but of course, I am not there to see for myself.

Thanks for the reply Semipro Tech. The muting felt isn't touching the strings. The dampers do seem to be coming well clear of the strings.
Something of a mystery, and one that I hope can be solved.
