System MenuP. 109ResonanceWhen the sustain pedal is depressed on an acoustic piano, all the dampers are lifted up allowing thestrings to vibrate freely. In this condition, when you play a note not only will the strings for the noteyou played vibrate but other strings will vibrate due to sympathetic resonance. The Resonancefunction simulates this phenomenon. You can select from three levels of Resonance.Off No resonance.Normal Simulates the natural resonance characteristics of an acoustic piano.Deep Produces a more intense resonance.L2 Selects normal resonance.L3 Selects deep resonance.R2 Turns off the resonance.L 1L 2L 3L 4L 5F 1 F 2 F 3 F 4 F 5 F 6 F 7R 1R 2R 3R 4R 5F1 Takes you to the System menu.
