Electronic musical instrument

摘要

An electronic musical instrument includes an excitation signal generating device (9), a plurality of loop circuits (42) and a coupling circuit. The excitation signal generating device (9) generates an excitation signal in accordance with musical tone designating information. Each of the plurality of loop circuits (42) at least delays an input signal in response to the musical tone designating information and repeatedly circulates the input signal therein. The excitation signal generated by the excitation signal generating device (9) is supplied to at least one of the plurality of loop circuits (42) as an input signal. The coupling circuits couples the plurality of loop circuits in accordance with a predetermined coupling form. At least one signal circulated in at least one of the plurality of loop circuits (42) is output as a musical tone signal to be generated. The electronic musical instrument further includes a memory circuit which stores a plurality of coupling forms. The coupling forms respectively indicates how to couple input and output terminals of the plurality of loop circuits (42). The input and output terminals are coupled to each other in accordance with one of the plurality of coupling forms.
