ABSTRACT:
An electronic instrument includes an input device having a plurality of channels to each of which an audio signal is input. A demodulation device demodulates audio signals and converts the audio signals into digital signals that control the electronic instrument. The electronic instrument also includes a feeding device that feeds the digital signals to a sound source and a detection device that detects whether or not the audio signals in any of the plurality of channels are modulated by the digital signals. A controller controls the demodulation device, in cases where it has been detected that any of the audio signals are modulated by the digital signals, so as to demodulate the digital signals from the audio signals that have been input to the channels, such that another channel's audio signals that are not modulated by the digital signals are output to an audio output.
