<P>PROBLEM TO BE SOLVED: To simplify installation of equipment and routing of cables constituting a system. <P>SOLUTION: A managing device MN, a teacher's terminal TM32, and two or more student's terminals TM1 to TM3 constituting this group teaching system of music are connected so as to be communicatable with each other through a general use digital network CN, and the terminals TM1 to TM32 comprise electronic musical instruments EM:EM1 to EM32 and converters CV:CV1 to CV32, respectively, and the managing device MN includes a digital mixer MX. The converter CV of each terminal can convert analog audio data, such as performance note and voice output from the electronic musical instrument EM into digital data and can make them flow over the network CN in a packet, and transmitting/receiving routes among respective terminals of the audio data over the network CN are controlled by a mixer MX. The converter CV of a predetermined terminal fetches the digital audio data from a predetermined terminal from the network CN, according to the transmitting/receiving route control and converts them into the analog data to input them to the electronic musical instruments EM. <P>COPYRIGHT: (C)2007,JPO&INPIT |
