Each of DAW processes (DAW1 to DAW7) and UI devices (M1 to M3, F1 to F5) which are controllers of the DAW processes regularly sends a heartbeat signal including identification information of a music system which the DAW process (DAW1 to DAW7) or UI device (M1 to M3, F1 to F5) belongs to, to a network (2) by broadcast or multicast. The heart beat signal can be transmitted to the network (2) using an Ethernet frame for UDP including the heartbeat signal in the data body, as a heartbeat packet. Based on the received heartbeat signal, it can be distinguished that the DAW process or UI device which sent the heartbeat signal is which of a device or music software process belonging to the relevant music system (WG1), a device or music software process belonging to another music system (WG2), and a device or music software process not belonging to any music system. |
