摘要： A user records a part of a piece of music performed on the composite audio system into and reproduces the performance from a floppy disc in ensemble with another part of the piece of music; while a compact disc player is producing an audio signal from audio data codes, the composite audio system produces event codes representative of local peaks in the audio signal for timing control, and stores these event codes together with event codes representative of note events and duration data codes in the floppy disc; while the composite audio system and compact disc player are reproducing the parts of the piece of music, the time intervals among the tones are prolonged and shrunk by using the event codes for timing control and actual local peaks so that the tones in one of the parts are produced synchronously with the tones of the other part.

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： In order to change an electronic sound between a piano sound generated without manipulation of a damper pedal and a piano sound generated under manipulation of the damper pedal, an electronic keyboard musical instrument assigns two tone generating channels to a depressed key for generating a fundamental tone signal representative of the piano sound generated by striking the set of strings and a resonating tone signal representative of a resonating sound generated through the resonance, and the resonating sound signal is mixed with the fundamental tone signal under manipulation of a pedal corresponding to the damper pedal, thereby making the electronic sound close to the piano sound.

摘要： A tuning device includes an analog-to-digital converter for converting sound waves propagated from a piano to an audio signal in synchronism with a sampling signal and a data processor for visualizing a difference between a target pitch of a tone and an actual pitch of the tone; since the sampling signal is less accurate in frequency, the data processor previously determines the frequency difference between a design frequency and an actual frequency of the sampling signal by using a calendar clock signal as a measure; the data processor eliminates noise due to the sampling signal from visual images of the pitch difference, and makes the visual images more accurate.

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： A music player/recorder includes two data sources, a controlling system and two sound source or a recording system; one of the two data sources supplies event codes representative of first tones and delta-time codes representative of time intervals between the events as defined in the MIDI standards to the controlling system, and the other data source supplies audio data codes representative of second tones and time codes representative of a lapse of time to the controlling system; the controlling system counts tempo clocks, and converts the number of tempo clocks to a reference lapse of time to see whether or not the difference between the lapse of time and the reference lapse of time is ignoreable; when the answer is given negative, the controlling system varies the time interval so that the first tone is produced synchronously with the corresponding second tone.
