MUSICAL SOUND CHANGER USING DATA MASK FOR ELECTRONIC MUSICALINSTRUMENT

摘要

A keyboard operated electronic musical instrument is disclosed which has a number of tone generators that are assigned to actuated keyswitches. The generated musical tones are selectively varied in tone color by multiplying tone data values by a masking function. A library of masking functions are stored and are selected by a control signal. Musical tones with time variant harmonics can be generated.
