ABSTRACT:
In an automatic rhythm performing apparatus, pattern memory stores rhythm pattern data of respective rhythm patterns for respective rhythm instrument tones as identified by channel numbers. Selected rhythm pattern data are read out together with the channel numbers and are supplied to corresponding tone generation channels for respective instrument tones according to the selected rhythm kind. There is provided a rewritable data memory storing channel alteration data for altering the channel number included in the read-out pattern data to another channel number. The rhythm pattern data read out from the pattern memory are supplied, as modified by the channel alteration data read out from the rewritable data memory, to the tone generation channels of the alteredly designated channel number. The channel alteration data of the data memory are rewritten by the manipulation of keys in the performance keyboard, whereby the rhythm patterns of the instrument tones are easily altered.
