[. . . ] B SD Piano Option Information Sympathetic Vibrations Sympathetic Vibrations When you play a chord on an acoustic piano and hold down the keys while the notes decay, the dampers on the corresponding strings remain up, and you hear a particular set of harmonics that evolve from the undamped strings. If you play the same chord and hold it with the sustain pedal, you'll hear a much different, richer set of harmonics as the notes decay. That's because all the strings are undamped, and each string gradually begins to vibrate at its resonant frequency, in response to the vibrations of the strings struck by the hammers. This phenomenon is called sympathetic vibration, and is an important component of the sound of an acoustic piano. The most noticeable of these sympathetic vibrations come from the strings whose fundamental pitches match the harmonics of the strings that were struck by the hammers. To create a more realistic acoustic piano sound for the SD Piano option, Kurzweil sound engineers have developed special effects settings that imitate sympathetic vibrations. When you're playing one of the SD Piano programs with ID 700­713, and you're not using the sustain pedal, the K2600's audio signal passes through FXBus 1, then to the AuxBus, which applies a typical room or hall reverb. When you use the sustain pedal, the signal passes FXBus 1 and FXBus 2 before going to the AuxBus. FXBus 2 applies a chain of reverbs programmed to resemble an acoustic piano's sympathetic vibrations. You can use the Data slider (or any physical controller sending MIDI 6) to adjust the level the sympathetic vibration effect. Modifying SD Piano Programs If you want to change the room ambiance on an SD Piano program without losing the sympathetic vibration effect, use the Studio Editor to assign a different effect on the AuxBus of the studio used by that program.
