PURPOSE:To intuitively, sensitively, and easily perform a performance operation and musical tone control by generating a musical tone according to a parameter automatically generated corresponding to voice vocalized from a player. CONSTITUTION:When the voice from a microphone is inputted after being converted to an audio signal, the level envelope of a frequency component signal analyzed by a frequency spectrum analyzer 7 is extracted from the frequency component signal by an envelope detector 8. An extraction result is converted to the parameter controlled by a model sound source by a pitch designation information converter 13 and a parameter converter 11. The prescribed parameter of a tube model sound source is controlled by each parameter outputted from a parameter generation supply part 4. Thereby, each parameter of the tube model sound source can be intuitively, sensitively, and easily controlled by the voice of the player. |
