Abstract:
It is possible to easily search necessary information from various information. Information on the music data performance position is registered. Music data such as audio data and MIDI data is played and during the performance, registration instruction is performed via a keyboard. Information is registered for the performance position corresponding to the timing when the registration instruction is performed. When searching information, the music data having the information registered is played and search instruction is performed via the keyboard or the like when the performance position containing desired information is reached. According to this instruction, the information registered at this performance position is searched and the information can be accessed. Since information is registered for the performance position of the music data, it is possible to easily and intuitively perform information registration and search. Moreover, since information is searched by the sound, there is no need of watching the screen.
