ABSTRACT:
In a musical instrument having one or more tone generators in which a plurality of data words are transferred sequentially from note registers in repetitive cycles at rates proportional to the pitches of tones being generated, apparatus is provided for varying the spectral content of tones having both harmonic and nonharmonic overtones. Control signals are used to vary the amplitudes of the overtones. An independent formant control signal causes the tones to have a time variant spectral quality.
