PURPOSE:To obtain excellent resonance effect by arranging respective volume correction data storage parts so that a volume correction instructing part can refer to the volume correction data of each different storage part in accordance with a control signal specifying at least a resonance state out of plural control signals. CONSTITUTION:The volume correction instructing part 9 selects the volume correction data storage part in accordance with the status signal SON of a switch 2. Namely, when a damper pedal is depressed in a piano (SON=1), a 1st volume correction data storage part 7 is selected, and in the other case (SON=0), a 2nd volume correction data storage part 8 is selected. Data ADJ stored in the selected volume correction data storage part are referred to and sent in accordance with keycode data KC outputted from a CPU 3. Since the volume correction data storage part to be referred by the instructing part 9 can be selected in accordance with the status signal SON of the switch 2, detailed volume correction due to a difference in the status of the damper pedal can be attained and an excellent resonance effect can be obtained. |
