PURPOSE:To obtain the device which makes better simulation of a natural musical instrument by simulating the influence that the vibrations of a vibrator exert on a side to be excited. CONSTITUTION:A start control signal is inputted to a nonlinear conversion means 43 by which the signal is subjected to nonlinear conversion. This signal is introduced to a circulating path 21 and begins to circulate. The waveform signal under circulation is partly inputted to a modulating means 47 to modulate the start control signal. Namely, the start control signal inputted is modulated in accordance with the waveform signal under circulation to approximate the musical tone generated in a musical tone waveform signal forming device 20 to the musical tone by the natural musical instrument at the time of circulating the start control signal in the circulating path having a prescribed resonance frequency after the nonlinear conversion. Further, the start control signal is inputted to 1st and 2nd signal delay means 22, 23 connected to the circulating signal path 21 to make the better simulation of the state in which the vibrations applied to the string of the rubbed string instrument progress on the string fixed at both ends or are reflected. |
