Electronic musical instrument.

摘要

An electronic musical instrument comprises a first wave form memory for storing a wave form corresponding to an attack portion of a musical tone and one period of a steady wave form produced after the attack, a second wave form memory for storing one period of a wave form different from the contents of the first wave form memory, a wave form reader which reads out the first and second wave forms from the first and second wave form memory, respectively, and an envelope generator which generates two separate envelope signals. The first wave form including the attack portion of the musical tone and the periodic second wave form are multiplied by the separate envelope signals, respectively, and then the products of the multiplication are added together. The sum of the products is provided as an output. Thus, the electronic musical instrument is capable of precisely simulating the attack portions of musical tones of a natural musical instrument and generating musical tone signals having steady part vividly simulating the musical tones of the natural musical instrument.
