PROBLEM TO BE SOLVED: To perform various automatic playings by an automatic playing device. SOLUTION: In addition to time-series playing event data, conditional event data are stored as automatic playing data stored in an external storage device 7 or a RAM 3. The conditional event data represent process conditions for determining whether corresponding playing event data are processed (transferred to a sound source circuit 10) in automatic playing according to detected states of environment and operation. A detecting device 12 detects the environmental state of the quantity of light, sound volume, temperature, humidity, atmospheric pressure, a vibration quantity, etc. The operation state of an operation element 4 (keyboard, foot switch, etc.), is detected. Playing event data given no process condition are processed unconditionally in the automatic playing. Playing event data to which the process conditions are added are processed only when the environment state or operation state detected in real time during the automatic playing meet the process conditions. |
