ABSTRACT:
A keyboard operated electronic musical instrument in which a number of tone generators are assigned to actuated keyswitches in which a flute chorus of similar tones at preselected pitch footages are generated by implementing a discrete Fourier transform employing a selected sequence of harmonic coefficients. Two stored harmonic coefficients suffice to generate a tibia type flute chorus. A harmonic sequence select logic in cooperation with signals derived from actuated tone switches provide the selected sequences of harmonic coefficients.
