PURPOSE:To provide the electronic musical instrument which can obtain natural resonance effect close to that of an acoustic musical instrument in consideration of even the operation state of a resonance effect operation element simulating the generation of specific resonance effect of the damper pedal of an acoustic piano, etc., in addition to the number of pressed keys and a range. CONSTITUTION:On the basis of a key number where an event is generated, a distribution coefficient EL is loaded (S700) from a distribution coefficient table generated by simulating how much, for example, respective keyboard positions, the damper pedal, etc., of the acoustic piano affect resonance effect, and a distribution coefficient EL loaded from a cumulative distribution coefficient AL according to key depression or key release is added or subtracted 9S710-S760). On the basis of this cumulative distribution coefficient AL, a parameter value selection table is looked up to determine a control parameter value, i.e., the multiplication coefficient of a multiplier, and the sound volume of a musical sound signal sent from a musical sound generation part is varied according to the multiplication coefficient. |
