A sound control apparatus is provided in a portable terminal for sounding a music tone in association with operation of the portable terminal, which is controlled by a main CPU. In the sound control apparatus, a memory memorizes music information representing a music tone and configuration information associated to a timbre of the music tone. An information acquiring section acquires the music information and the configuration information from the memory. A tone generating section is configured by the acquired configuration information to create a timbre specified by the configuration information. The tone generating section operates according to the acquired music information to generate the music tone being represented by the music information and having the specified timbre. A dedicated CPU is provided separately from the main CPU for controlling the memory, the information acquiring section and the tone generating section.

An electronic musical instrument is constructed to treat music information associated to music tones, and can be coupled to a mobile wireless terminal set communicable with a public communication network. In the electronic musical instrument, a main block processes music information for generation of music tones, the processed music information being transferable for effecting remote generation of the music tones. A memory block is controlled for memorizing music information. A control block controls the memory block to memorize the processed music information and to feed the memorized music information to the mobile wireless terminal set for transfer of the music information through the public communication network. Further, the control block feeds music information received by the mobile wireless terminal set through the public communication network to the memory block, and controls the memory block to memorize therein the fed music information. The main block processes the memorized music information for generation of music tones.

In accordance with a request from a portable telephone, a sound data delivering serverdelivers a trial-listening music data to the portable telephone without charging a fee to a user of the portable telephone, or delivers a regular music data to the portable telephone upon charging a fee to the user. The delivered trial-listening music data is actually reproduced by the portable telephone; however, the number of reproduction times is limited, and the trial-listening music data is erased from a memory (RAM) of the portable telephone after the trial-listening music data is reproduced for the predetermined number of reproduction times. Thus, a system is provided in which the user of the portable telephone can obtain the trial-listening music data of an incoming call melody without being charged for the fee, and can actually reproduce the trial-listening music data with the use of the user s portable telephone.

Sound data delivering system, sound data delivery method, delivering server utilized in the sound data delivering system, client-side terminal utilized in the sound data delivering system, and computer-readable recording medium containing a program applied to a computer utilized in the sound data delivering system

A music data distribution system for distributing music data to an external device connected to a network, comprises: a storage device that stores first music data; a receiver that receives a music data distribution request from the external device connected to the network, the music data distribution request comprising at least music data identification information and music data quality information; a reading device that reads the first music data from said storage device in accordance with the music data identification information; a quality converter that converts the first music data into second music data having a quality different from the first music data in accordance with the music data quality information; and a transmitter that transmits the first or the second music data to the external device in accordance with contents of the music data distribution request.

Music data distribution system and method, and storage medium storing program realizing such method

A communication apparatus having value added functions useful for musicians is provided. A tempo signal having a cycle corresponding to a tempo set by a user through an operation device is generated, a musical tone signal equivalent to a metronome sound is generated in accordance with the generated tempo signal, and the metronome sound is generated in accordance with the generated musical tone signal. Therefore, the present invention can contribute to further increasing the added value of a communication apparatus, which is requisite for musicians.
