Problems with sound duration

[UNOQUAD]

Hi! I have a MK1 Rhodes piano. I'm learning to fine-tune it and adjust the nuances of the sound with the adjustment screws. My problem is that there's a note/key, no matter how much I adjust the screws, fades slightly before comparing to the surrounding notes.

I would appreciate some help, and thank you in advance

Hi, have you replaced the tone bar grommets? sometimes they wear out unevenly and some notes don't sustain right while the rest are fine.

If it is one of the high range notes with the flat tone bar, you could try adding a tone bar clip, or a magnet to the end of the effected tonebar(s) and see if that helps.

If the effected notes sound weak or have a thud to the attack and are all in the same range of the keyboard you might need to do a slight strike line adjustment.

Take a look at the hammer tips, does the hammer for the problematic note seem in line with the rest?

If none of those help you probably just need to replace some tines.
