Automatic performance device

A storage device being capable of communicating with a performance information output device for outputting performance information and an automatic performance device for reproduction the performance information in synchronization with a video distributed by a moving image distribution server for distributing the video and an audio, the storage device comprising:

• a performance data receiving unit that receives performance data having a combination of the performance information and the time information from the performance information output device each time the performance information is generated by the performance information output device without passing through the moving image distribution server, the time information indicating the time when the performance indicated by the performance information was carried out,
• a storing unit that stores the performance data received by the performance data receiving unit;
• and
• a performance data transmitting unit that transmits the performance data stored in the storing unit to the automatic performance device without passing through the moving image distribution server in parallel with the storing of the performance data received by the storing unit.
