ABSTRACT:
In a musical instrument having one or more tone generators in which a plurality of data words corresponding to the amplitudes of a corresponding number of evenly spaced points defining the waveform of one cycle of an audio signal are transferred sequentially from a note register to a digital-to-analog converter in repetitive cycles at a rate proportional to the pitch of the tone being generated, apparatus is provided for varying the spectral content of the tone in response to control signals. A loudness control signal causes loud tones to be produced with a greater number of harmonics than those for a soft tone. A formant control signal also causes the tones to have a time variant spectral quality.
