Scaling of each harmonic coefficient for electronic musical instrument
2010-03-11
AbstractA method of scaling a harmonic coefficient is employed, and envelope smaller in number than the number of harmonic orders are produced. One of the envelope is selected for each harmonic order and output as a scaling value. This enables the production of a musical tone imitative of a desired one, decreases the number of envelope generators needed, and permits simplification of the entire system configuration and signal processing.ClaimsWhat is claimed is: /> />1.
