ABSTRACT:
A keyboard operated electronic musical instrument is disclosed which has a number of tone generators that are assigned to actuated keyswitches. Musical tones are produced by computing a master data set which defines the data points for a period of the musical waveshape. The computation uses a preselected set of harmonic coefficients. The time required to complete a master data set computation is reduced by dividing the set of harmonic coefficients into a number of subsets of coefficients. The harmonic coefficients are combined by a combination of a reverse addressing and complementing in a logic that decreases the required number of computation time intervals.
