Abstract

A plurality of operators provided on a communication terminal, such as a portable phone, are assigned in advance to functions for generating tones, and a tone generation starting signal is generated in response to depressing operation, by a user, of any one of the operators. The communication terminal transmits, to a tone generator module, performance content data having added thereto operation time information representative of a time when the user's depressing operation has taken place. Upon receipt of the performance content data from the communication terminal, the tone generator module carries out a process based on the tone generation starting signal on the basis of the operation time information added to the performance content data.
