ABSTRACT:
A keyboard electronic musical instrument comprises a note information processing device capable of processing note information required for automatic arpeggio and automatic bass performances. This note information processing device includes a generation circuit for generating a plurality of note information representing a plurality of notes to be sounded in relation to the key depression, a selection circuit for sequentially selecting a note information designating a note to be sounded from among the plurality of note information from the generation circuit in accordance with a predetermined priority order; an output circuit for delivering out the note information selected by the selection circuit, the selection at each sequence being conducted dependent on the selection at the preceding sequence. The selection circuit includes a first selector which selects note information of higher (or lower) notes than the note information outputted at the preceding sequence and a second selector which selects note information of the lowest (or highest) one from among the information selected by the first selector. The note information processing device is used commonly for the automatic arpeggio performance and the automatic bass performance in a time division manner.
