ABSTRACT:
A method and apparatus for producing sounds from one or more-time overlapg sequences of one or more electrical pulse signals having a frequency corresponding to the pitch of the sound to be produced from the signals holding the pulse width or pulse pause width in each sequence substantially constant for signals corresponding to a range of pitches of the sound to be produced. The pulse widths or pulse pause widths are then relatively abruptly changed over a short interval in pitch at the upper limit of the range. In this way, the shape of each pulse in a sequence and the phase between pulses in concurrent sequences which determine the timbre of the sound remains the same over the range of sounds to permit the method and apparatus to accurately duplicate the sounds of traditional musical instruments.
