摘要： An automatic player piano includes a voice recognizer and a piano controller; while a user is singing a song, the voice recognizer analyzes the voice signal representative of vocal tones so as to determine the loudness and pitch of each vocal tone, and successively sends music data codes each expressing a note-on event, key number closest to the pitch of vocal tone and a velocity and music data codes each expressing a note-off and the key number to the piano controller together with music data codes duplicated from a set of music data codes stored in the memory; and the piano controller selectively drives the black and white keys with driving signal produced on the basis of the music data codes so as to play the accompaniment of the song.

摘要： An ensemble controller records a performance on a MIDI musical instrument in a data field of a MIDI file synchronously with playback of a piece of music stored in a compact disc player, and the data read-out speed is stored in the control data field of the MIDI file together with an audio identification code assigned to the piece of music reproduced; when the performance is reproduced synchronously with the playback of the compact disc player, the ensemble controller adjusts a clock signal to a frequency corresponding to the data read-out speed; while the ensemble controller is making the composite apparatus reproduce the ensemble, the magnetic disc driver clocks the time intervals between the data transmission of event codes by using the clock signal of the same frequency; this results in the perfect ensemble.

摘要： An electronic keyboard musical instrument includes a plurality of sound generating channels selectively assigned to pairs of fundamental sound signals and pairs of resonant sound signals, and a channel controller assigns the sound generating channels to a new pair of resonant sound signals after release of sound generating channels from the assignment to a pair of resonant sound signals for a stereophonic sound with the minimum loudness when the sound generating channels have already assigned to the predetermined pairs of resonant sound signals so as to concurrently produce a large number of stereophonic sounds.

摘要： A synchronous player system is used for recording an ensemble between an automatic player piano and an audio player and playback therebetween; while a user is playing on the automatic player piano in ensemble with the audio player, reference characteristic data of the performance is extracted from the audio music data, and are stored in a memory together with the event codes; when the user instructs the synchronous player system to reproduce the performance in ensemble with the same piece of music recorded in another compact disc, the synchronous player system extracts objective characteristic data from the audio data recorded in the other compact disc, finds differences through a correlation analysis, by way of example, and rescheduling the timing to reproduce the note events for synchronously controlling the automatic player piano and audio player.

摘要： Automatic player pianos and internet form a music performance system for a music session on the automatic player pianos through data communication between the automatic player pianos, and a communication time lag and mechanical time lag are unavoidably introduced between the data transmission and the data reception and between the data reception and tone generation; one of or both of the time lags are compensated by employment of an electronic tone generation, presumption of key positions or presumption of key event so that the slave automatic player piano generates the tones almost concurrently with the tones generated through the master automatic player piano.

摘要： An electronic keyboard musical instrument is responsive to a step-on of a soft pedal so as to impart effects similar to those of a soft pedal of an acoustic piano to an electronic sound; a tone generator incorporated in the electronic keyboard musical instrument causes a series of waveform data codes to be read out at a higher speed so as to slightly increase the pitch of an electronic sound, an envelop generator to give a gentle envelop with a small attack and a long sustain to the electronic sound and a filter circuit to emphasize a certain high frequency component, thereby making the electronic sound to be quite close to the piano sound produced under the step-on of the soft pedal.
