  • Publication number: 20160133243
    Abstract: The present invention allows a user to visually identify musical performance data to be reproduced. The user utilizes a musical performance device (100) and an image pickup device (200) that picks up an image of the musical performance to record the musical performance data onto a musical performance recording server device (400) with a musical performance date/time. Further, image data is recorded onto an image recording server device (300) with the image pickup date/time. To reproduce the musical performance, the user visually selects the image picked up from among the images recorded on the image recording server device (300). The musical performance data associated with the musical performance date/time close to the image pickup date/time of the selected image is identified on the musical performance recording server device (400), and the musical performance is reproduced on the musical performance device (100) based on the identified musical performance data.

  • Patent number: 8383925
    Abstract: A music station is connected through a communication network to another music station, and pieces of music data expressing an exhibition performance on a automatic player piano and pieces of voice data expressing tutor's explanation are transmitted from the music station to the other music station through different communication channels; and a close-talking microphone and a bone conduction microphone are incorporated in a sound collector on the music station, and a vibration signal from the bone conduction microphone is examined to see whether or not the cord of tutor vibrates; when the answer is given affirmative, a voice signal from the close-talking microphone is relayed to a transmitter module so that the sound collector does not permit the transmitter module to transmit the voice signal expressing noises such as the tones; whereby the music performance system prevents the trainee from tones reproduced from a headphone.

  • Patent number: 8314319
    Abstract: A plurality of musical instrument is connected to a server device through a network to form a storage system. The musical instrument generates performance data, and sends the performance data to the server device every time the performance data is generated. The server device receives the performance data sent from the musical instrument. The server device has a clock unit that measures date and time, and a storage unit that stores the performance data received by the receiving unit. Further, a file generation unit of the server device divides a polarity of the performance data stored in the storage unit into blocks based on the date and time of the performance data measured by the clock unit when the performance data is received by the receiving unit, and generates performance files corresponding to the blocks of the performance data.

  • Patent number: 8138407
    Abstract: In order to establish an automatic player piano and a home theater system in synchronization for ensemble, a set of playback pattern data expresses a series of pitch names, and is stored in a memory system independent of an audio data file and a music data file; while an audio signal is being supplied from a playback system to a synchronizer of the automatic player piano, the synchronizer extracts samples from the audio signal, and determines a series of pitch names through an FFT and a quantization; the series of pitch names of the samples is compared with the playback pattern data what part of the playback pattern data expresses the series of pitch name; since the each sample appears over an extremely short time period, the synchronizer accurately determines a lapse of time, and selects a note event data code to be processed from the music data file.
