Abstract
Electronic music apparatus includes: a tone generator section for generating a tone signal in response to operation of a performance operator unit; an external input section for receiving a tone signal from the outside; a mixer section for generating mixed tone signals by mixing the tone signal generated by the tone generator section and the tone signal received via the external input section; an external output section for outputting the tone signal, generated by the tone generator section, to the outside before that tone signal is mixed with the tone signal received via the external input section; and an audio output section for audibly outputting the mixed tone signals from the mixer section. Because the tone signal received via the external input section is not fed to the external output section, no unwanted howl is produced even where a plurality of the electronic music apparatus are connected together.
