PROBLEM TO BE SOLVED: To produce a normal musical sound and a musical sound of a special musical performance method in a seamless state, based on a sound production operation of a person who performs an electronic musical instrument, in a technical field of a sound production control of the electronic musical instrument.SOLUTION: A voice sensor 102 detects a voice which is vocalized. A breath sensor 101 detects at least one of a pressure and a flow rate of expired air following to vocalization. A pitch determination part 205 determines a pitch based on an operation state of pitch designation plural keys 204. A sound source 207 generates a musical sound of a pitch instructed by an instruction part 206. A processing part 209 generates a processing sound signal for generating a special musical performance sound by processing the voice detected by the voice sensor 102. A gain determination part 211 determines a gain based on an output of the breath sensor 101. An accumulator 214 synthesizes the musical sound signal output from the sound source 207 and the processing sound signal output from the processing part 209, and a multiplier 215 controls so that the gain is set to the gain determined by the gain determination part 211.SELECTED DRAWING: Figure 2 |
