ABSTRACT:
In a musical tone generator system, rhythm pattern data are read out from a rhythm pattern memory so that the formation of the tone signal specified by the rhythm pattern data is controlled by allocating the tone signal to one of the tone signal forming channels of a signal forming circuit, which is thus enabled to output from each of the tone signal forming channels the tone signal specified by the rhythm pattern data with the result that a sequence of tones is automatically generated in accordance with the rhythm pattern data. When any one of the tone select keys is activated, the formation of the tone signal corresponding to the tone designated by the activated tone select key is controlled by allocating the tone signal to one of the tone signal forming channels. The tone signal forming circuit is now enabled to form in and output from each of the tone signal forming channels a tone signal which corresponds to the tone designated by the activated tone select key. Thus, the tone signal forming circuit generates a sequence of tones with an automatically controlled rhythm pattern and the tone designated by the activated tone select key. The allocation of the tone signal corresponding to the tone designated by the activated tone select key and the tone signal specified by the rhythm pattern data is controlled so that the former is allocated to one of the tone signal forming channels preferentially over the latter.
