The personal computer2downloads a controlling program from the server4. The electronic organ1is set to be a listening trial mode by an operation of the personal computer2. In the listening trial mode, an output of a data in a temporally storage area is prohibited. The server4provides a first encoded performance data to the personal computer2, and the personal computer2decodes the received first encoded performance data.
