1. An electronic musical instrument comprising:
a performance operator configured to receive a performance operation;
at least one memory configured to store executable instructions; and
a processor configured to execute the executable instructions stored in the at least one memory to cause the electronic musical instrument to:
acquire a click sound signal through a first channel from an external source via a communication interface;
acquire a backing sound signal through a second channel different from the first channel from the external source via the communication interface, simultaneously with acquiring the click sound signal;
generate a musical sound signal according to the performance operation received by the performance operator;
acquire setting volume information of a click sound corresponding to the click sound signal, setting volume information of a first backing sound corresponding to the backing sound signal, setting volume information of a second backing sound corresponding to the backing sound signal, setting volume information of a first musical sound corresponding to the musical sound signal, and setting volume information of a second musical sound corresponding to the musical sound signal;
adjust a first volume balance of the click sound signal, the backing sound signal, and the musical sound signal based on the setting volume information of the click sound corresponding to the click sound signal, the setting volume information of the first backing sound corresponding to the backing sound signal, and the setting volume information of the first musical sound corresponding to the musical sound signal, respectively;
mix the click sound signal, the backing sound signal, and the musical sound signal whose first volume balance has been adjusted to obtain a first output sound signal and output the first output sound signal to a first output destination;
adjust a second volume balance of the backing sound signal and the musical sound signal based on the setting volume information of the second backing sound corresponding to the backing sound signal and the setting volume information of the second musical sound corresponding to the musical sound signal, respectively; and
mix the backing sound signal and the musical sound signal whose second volume balance has been adjusted to obtain a second output sound signal that excludes the click sound signal and output the second output sound signal excluding the click sound signal to a second output destination different from the first output destination.
