In a musical system, a transmitting device transmits performance data, a first receiving device is connectable to the transmitting device to receive and pass the performance data, and a second receiving device is connectable subsequently to the first receiving device to receive therefrom the performance data. The transmitting device operates to transmit first performance data arranged to drive a first sound source to generate musical tones and to transmit second performance data arranged to drive a second sound source of a type different than the first sound source. The first receiving device operates if the same has the first sound source for admitting the first performance data so as to drive the first sound source and for issuing a control message to the second receiving device. The second receiving device having the second sound source operates in response to the control message to prohibit admission of the second performance data to thereby disable the second sound source.
