PROBLEM TO BE SOLVED: To prevent malfunction of a performance device in a case where a signal is in an unstable state.SOLUTION: A plurality of performance devices are divided into a plurality of groups, group unit control means is provided for each group, and performance control means is configured as group integrated control means for integrally controlling the plurality of group unit control means. Connecting means for connecting the group integrated control means and each group unit control means to enable communication is provided. The group includes a movable group constituted of the performance device including a movable object. The group unit control means generates internal data for controlling the movable group in response to an input of control data. The connecting means includes permission signal connection means for transmitting a permission signal for permitting output of the internal data. The permission signal connection means includes start-up signal fixing means for fixing the permission signal to be input to the group unit control means, when starting up the group unit control means. |
