  • Patent number: 8735710
    Abstract: Provided is an electronic stringed instrument comprising: a pickup that detects vibration of a string; a feedback operator used to select a level of feedback effect; a feedback control device that controls to add a feedback effect to a tone signal based on the vibration of the string detected by the string vibration detection device and based on the selected level of feedback effect from the feedback operator; and an output device that outputs the tone signal to which the feedback effect is added by the feedback control device.

  • Patent number: 7812242
    Abstract: Various embodiments of the present invention are directed to providing a musical tone control device for carrying out appropriate control in user-performed operations. A pitch parameter value PB set by a pitch bend wheel may be loaded and a determination may be made whether the pitch parameter value PB is within a specified range. If the pitch parameter value PB is within the specified range, a time t may advance by 1, and a determination may be made whether the time t has reached t1. If the time t has reached t1, an amplitude value from a low frequency oscillator (LFO) table corresponding to the time t may be read out from the LFO table. The vibrato value VI may be calculated by multiplying the amplitude value and the vibrato depth. The pitch parameter value PB and the vibrato value VI may be added and transmitted to the sound source.

  • Patent number: 6762358
    Abstract: A waveform reproduction apparatus and process for carrying out waveform reproduction without delays. Waveform data expressing first and latter half portions of a musical tone waveform are stored on a storage device. In response to a tone generation start indicator, waveform data that express first half portions corresponding to the tone generation start indicator are successively read out and corresponding musical tone waveforms are formed. Following this, the waveform data that express latter half portions corresponding to the tone generation start indicator are successively read out and corresponding musical tone waveforms are formed.

  • Patent number: 5763805
    Abstract: A performance information transmission system includes a performance information transmitter device and a performance information receiver device which are capable of correcting transmission errors in event information transmitted from the performance information transmitter device to the performance information receiver through a wire or radio communication. This correction does not require another transmission passes, cause a delay of the generation of the musical tone, or cause difficulties in restoring the burst error. The performance information transmitter device is equipped with state information generating device which generates state information for indicating the control state of a musical tone of a predetermined musical tone after a change has occurred in the event information. A transmit device transmits sequentially the event information and the state information generated by the state information generating device.

  • Patent number: 5295123
    Abstract: First tune information of playing information is read out from playing information storage means to a selected one of predetermined positions and then a selected one of a plurality of pieces of second tune information is read out without incurring the possibility of introducing discontinuity or unnaturalness between musical sounds reproduced from the first tune information and the second tune information.The predetermined positions on the first tune information are made to correspond to the plurality of pieces of second tune information, and control means is provided for controlling tune information read means so that when the first tune information has been read out to the selected one of the predetermined positions respectively corresponding to the plurality of pieces of second tune information, that one of the pieces of second tune information corresponding to the selected predetermined position is automatically read out.

  • Patent number: 5212676
    Abstract: A performance information recording/playing apparatus corrects recording/playing errors in performance information which is reproduced from or recorded to a recording media by a performance information playing/(recording) device in accordance with event information. The performance information recording device includes a state information generating device which generates state information indicating a state of musical tone for a predetermined musical tone after a change has occurred in event information which represents a change in the predetermined musical tone, and a recording device for recording the event information and the state information in a recording media sequentially. The performance information playing device includes a playing device for playing event information which represents a change in a predetermined musical tone and state information which indicates a state of a musical tone for the predetermined musical tone, this information having recorded in a recording media.
