The apparatus includes an operator which can be movably operated in a predetermined direction and simulates a bow, a converter which stores a plurality of nonlinear characteristics. The nonlinear characteristics represent a relation between pressure signal which is added on the operator by a player and control pressure signal which simulates real rubbing pressure added on the string. To realize real performance by the bow, the converter converts the pressure signal into the control pressure signal to be changed in accordance with the position of the operator even if the pressure signal is constant.

  • Patent number: 5262584
    Abstract: An electronic musical instrument, in which a phrase for about one bar is assigned to each of keys across two octaves, a note data string of each phrase is read out from a memory in accordance with a one-finger key operation, and corresponding tones are generated. Key numbers, key depression velocities, and key depression timings of a series of key operations in a phrase play mode are recorded in a recording medium. In a playback mode, a note data string of a phrase corresponding to a playback key number is read out from the memory. Tone generation strength data in the note data are multiplied with the playback key depression velocity, thus obtaining a modified note data string. Playback tones of a phrase play close to an actual play can be generated by modifying key depression strengths of phrase tones pre-programmed in the memory.

    Abstract: An electronic piano system provides an automatic performance piano capable of automatically carrying out pre-recorded performance, plus a key-return speed detecting unit and/or a string-striking speed presuming unit. When a depressed key is released so that a key is to be returned to its original position, a key-return speed is occurred, which is detected by the key-return speed detecting unit. On the other hand, when the key is depressed so that a hammer strikes a string in order to generate the corresponding sound, a string-striking speed of hammer is occurred. Based on a detected key-striking speed, the string-striking speed presuming unit presumes the corresponding string-striking speed. Thus, by use of the detected key-return speed and/or presumed string-striking speed, the automatic performance can be carried out with high fidelity.

    Abstract: An electronic stringed instrument employs a plurality of sensors or monitors for instrument performance. Preferred sensors or monitors include a detector for detecting that a string of the instrument is vibrated, an apparatus for evaluating a string-vibration strength or a string touch, an apparatus for discriminating a fret operation position on a fingerboard or a fundamental frequency of a vibration of the vibrated string, a tremolo arm sensor, and a string-bending sensor. These performance input parameters are assigned to various control functions for musical tones generated by a sound source and/or various control functions for effects added to these musical tones by an effector. The function assignment is preferably programmable. In an operation, a music control apparatus controls the sound source and/or effector in response to a performance monitor so that musical tones for the strings can be distinguished from each other or effects for the musical tones can be distinguished from each other.

  • Patent number: 5119712
    Abstract: Even though a control apparatus adapted for controlling a sound source of a keyboard type musical instrument is used with any type of electronic instruments connected therewith as a performance input apparatus, the control apparatus can provide after-touch effect as a user expects. Especially when a wind instrument playing mode is selected the control apparatus generates control data in a state inherent to a wind instrument playing mode on the basis of the received after-touch data to control musical tones, and suppresses amplitudes of variations of the control data when the after-touch data vary within a low amplitude range. Further, when the control apparatus has received a plurality of after-touch data, the control apparatus obtains only one of after-touch data, which is to be processed, thereby applying after-touch effect to musical tones with no time delay after a player's playing operation.

  • Patent number: 5113742
    Abstract: When picking of a string is performed, the vibration of the string is detected accurately and quickly. When a fret operation position is changed during generation of a musical tone caused by the string picking, the pitch of the musical tone is changed to the one corresponding to the new fret operation position without generating a new musical tone. When the same string is stroked successively, the succeeding musical tone is generated while keeping the reverberation of the previous musical tone. The musical tone once generated will be stopped from being generated upon elapse of a predetermined time from the beginning of the tone generation, irrespective of the type of its timbre. When a fret operation state is changed to an open-string operation state after the string picking, the generation of the musical tone being generated stops at that timing.

  • Patent number: 5107746
    Abstract: A system is provided for tracking the three-dimensional position of an object within a three-dimensional region by triangulation techniques to generate signals corresponding to such three-dimensional positions. The signals may be used to drive a music synthesizer. Triangulation may be by the use of at least three spaced apart ultrasound emitters cooperating with ultrasound receivers located on a body moving in the three-dimensional region. The position of each ultrasound receiver is calculable by triangulation from data from ultrasound pulses received by the receiver from the emitters. A sound map may be made of the region so that similar signals may drive the synthesizer differently for different sub-regions.

  • Patent number: 5099738
    Abstract: A MIDI-compatible musical instrument controller includes a keyboard having a plurality of keys and circuitry for electronically scanning the keyboard and for producing individual key-depression signals for each key being depressed. Each of the individual key depression signals identifies the key with which it is associated, commences when the key is depressed, and terminates when the key with which it is associated is released. A plurality of note tables is provided for converting each of the individual key depression signals to MIDI note-identifying information. Each note table defines each key as one or more preselected musical notes such that no two of such tables define the plurality of keys with the same MIDI note-identifying information. One of the note tables is selected in response to a user command.

  • Patent number: 5099739
    Abstract: The musical tone generating apparatus includes at least a waveform memory for storing waveform data, a stereophonic effect giving portion, left and right sound systems. The stereophonic effect giving portion gives stereophonic effect to the waveform data read from the waveform memory so that the left and right sound systems can generate left and right musical tones respectively based on the same waveform data outputted from the stereophonic effect giving portion. This stereophonic effect giving portion includes at least one digital filter whose filter coefficient can be adequately selected. This digital filter filters out the waveform data, and then the filtered waveform data are supplied to one of the left and right sound systems so that frequency characteristic of the left musical tone will be different from that of the right musical tone. Meanwhile, two digital filters can be provided at both inputs of the left and right sound systems.
