pianow
well let me rephrase, i think about sympathetic and sustain resonance as two different things
the sympathetic is when you hold a key/chord and hit another one that's harmonically related to the first one and then they'll resonate with each other
but the sustain resonance is when you press the sustain pedal, all the strings will resonate with each other
the question is, in the original modern d, even with sustain pedal depressed, you could have added sympathetic resonances and they removed that? or they removed the actual sustain resonances when the sustain pedal is depressed? because the first one is kinda of bug and not true to any piano that I've ever played and I'm glad they removed it, but the second one is one of the very basic effects with a sustain pedal depressed
sorry that was confusing
