On all piano sounds, Alicias Keys, Grandeur, Noire etc - my B4 key flip flops between B4 and B5 when sustain pedal is depressed, and I'm not sure why this is. A4 nearly does this but not to the extent the B4 does. Is this a sympathetic resonance thing, or is there are problem? It's kind of annoying because it happens more often as a B5 sounding note than B4 which is a bit odd. Is there any way to change this in the settings?
