Apparatus for producing ensemble tone in an electric musical instrument |
摘要 |
An ensemble effect is produced in a digital tone generator by providing a master data set of words having values corresponding to the relative amplitudes of equally spaced points along one cycle of a waveform of a musical tone in which the fundamental frequency is deleted. These values are read sequentially and repetitively from a memory to produce a first analog tone. A second analog tone is produced by multiplying a data set corresponding to the fundamental frequency by a low frequency sinusoid. The first and second analog tones are summed to yield a musical tone having an ensemble effect.
