PURPOSE:To realize a tone difference generated according to the picking position difference of a string. CONSTITUTION:A drive signal X is supplied to delay circuits 10 and 11, in each of which a separate delay time is set, respectively. Output signals of these delay circuits 10 and 11 are sent to an adder 12. Signals, circulating a loop circuit 14 simulating the actions of the strings of a string instrument, are also supplied besides the output signals to the adder 12, and all these signals are added to be sent to a delay circuit 13. Signals circulating the loop circuit 14 are picked up as musical sound signals Y from the output end of the adder 12. A delay time set to the delay circuits 10 and 11 is changed according to a difference of an excitation position for a string of a natural musical instrument, and a delay time for a whole string is set to the delay circuit 13. |
