Electric musical instrument system, control method and non-transitory computer readable medium t hereof

A control method of an electric musical instrument system comprising a musical sound transmitting means which transmits an audio signal emitted from a musical instrument and a musical sound receiving means which receives the audio signal, wherein

• the music sound transmitting means and the musical sound receiving means both have a first mode and a second mode in which power consumption is lower than that in the first mode, wherein the second mode of the musical sound transmitting means has lower power consumption than the first mode of the musical sound transmitting means, and the second mode of the musical sound receiving means has lower consumption than the first mode of the musical sound receiving means,
• the method comprising:
• detecting rocking of the musical instrument by the musical sound transmitting means;
• transmitting the audio signal by the musical sound transmitting means to the musical sound receiving means in the first mode of the musical sound transmitting means and,
• in a case when rocking of the musical instrument is detected by the musical sound transmitting means, the musical sound transmitting means transmits detected information to the musical sound receiving means in the second mode of the musical sound transmitting means;
• receiving the audio signal or the detected information by the musical sound receiving means;
• and
• processing the audio signal that has been received in the first mode of the musical sound receiving means and, in a case when the detected information is received in the second mode of the musical sound receiving means, cancels the second mode of the musical sound receiving means and switches to the first mode of the musical sound receiving means.

A non-transitory computer-readable medium storing a control program of an electric musical instrument system comprising a musical sound transmitting means which transmits an audio signal emitted from a musical instrument and a musical sound receiving means which receives the audio signal, wherein the music sound transmitting means and the musical sound receiving means both have a first mode and a second mode in which power consumption is lower than that in the first mode, wherein the second mode of the musical sound transmitting means has lower power consumption than the first mode of the musical sound transmitting means, and the second mode of the musical sound receiving means has lower consumption than the first mode of the musical sound receiving means,

• the control program causes a computer to execute a process, the process render the musical sound transmitting means and the musical sound receiving means performing following steps:
• detecting rocking of the musical instrument by the musical sound transmitting means;
• transmitting the audio signal by the musical sound transmitting means to the musical sound receiving means in the first mode of the musical sound transmitting means and,
• in a case when rocking of the musical instrument is detected by the musical sound transmitting means, the musical sound transmitting means transmits detected information to the musical sound receiving means in the second mode of the musical sound transmitting means;
• receiving the audio signal or the detected information by the musical sound receiving means;
• and
• processing the audio signal that has been received in the first mode of the musical sound receiving means and, in a case when the detected information is received in the second mode of the musical sound receiving means, cancels the second mode of the musical sound receiving means and switches to the first mode of the musical sound receiving means.
