High-Pitched Whine is
Produced
When listening through headphones:
Certain piano tones that feature vibrant, sparking sounds contain a large high-frequency
component, which may make it appear that a metallic reverberation has been applied.
This faithfully reproduces the characteristics of acoustic pianos, and does not indicate any
malfunction. Since this reverberation becomes particularly audible when supplemented by
heavy reverb, you may be able to diminish the problem by reducing the amount of reverb
applied to the sound.
When listening through speakers:
Here, a different cause (such as resonance produced by the RD-300GX) would be suspect.
Consult your Roland dealer or nearest Roland Service Center.
