Abstract
A harmony generator for an electronic organ, wherein the identity of played keys of the keyboard(s) is read into a storage device and then operated upon by a data processing device such as a microcomputer, so as to supplement the played note data with additional data designating 'fill-in' notes which are to be sounded in addition to those actually played. The data contained in the storage device, as supplemented, is then used to control the transmission of tone generator signals to the audio output system of the organ. In a preferred embodiment of the invention, the criteria used to select fill-in notes cause notes corresponding to the nomenclatures of played notes of the accompaniment keyboard to be sounded as though played in the octave below the lowest note played on the solo keyboard. Other fill-in criteria are also contemplated. The fill-in notes are generated by combining played accompaniment data with masks. The identity of these masks is based upon the nomenclature of the lowest or highest played note of the solo keyboard. These masks can either be looked up in a table or generated by a suitable algorithm. Fill-in notes can be generated simultaneously by more than one set of criteria, and the fill-in notes so produced can be separately voiced.
