  • Patent number: 5900564
    Abstract: A terminal apparatus is connectable to a host station and is responsive to a command to execute an application program to treat music data. In the terminal apparatus, a local storage locally stores an old version of software containing music data and various application programs which are selectively executed to treat the music data. An interface is optionally activated prior to execution of an application program for communication with the host station having a remote storage which remotely stores a new version of software including music data and various application programs which are made available latest by the host station. A controller operates when the interface establishes the communication with the host station for downloading the new version from the remote storage of the host station and for transferring the downloaded new version to the local storage so as to renew the old version stocked in the local storage by the new version.

  • Patent number: 5399801
    Abstract: A desired rhythm instrument tone color can be assigned to a pad type performance operator. A desired type of repeated-tone mode, e.g., roll, flam or echo, can be selected by a switch operation or other suitable means. Upon operation of the performance operator, repeated tones having a rhythm instrument tone color assigned to the performance operator are generated with a stroke pattern having a characteristic peculiar to the tone color.

  • Patent number: 5382750
    Abstract: An electronic musical instrument has an automatic playing device which conducts an automatic musical performance at a tempo set by manually tapping of a pad before the beginning of the performance. The automatic playing device also starts the automatic performance based on the detection that the number of the tapping has coincided with the predetermined number. The tempo is set according to an interval between the successive tapping. The successive taps can be the latter two taps when the tapping is made for a number of time of music. Also, the electronic musical instrument is equipped with a tap voice output device that outputs counting voices, such as `one`, `two`, `three`, for each tapping.

  • Patent number: 5373097
    Abstract: An electronic musical instrument is disclosed wherein the musical tone parameter such as the tone volume, tone color, acoustic reverberation, pan-pot and the like can be varied over time. The invention provides an electronic musical instrument including an operational device, a memory, a readout section, a control section and a tone generator. The operational device can be implemented in a stick type operator for example. The operational device generates operational data which vary over time in response to operations applied thereto. The operational data generated by operational device are consecutively stored in the memory. The readout section can be implemented in a CPU for example and consecutively reads out the operational data from the memory. The control section can be implemented in a CPU for example and generates a musical tone parameter which varies over time on the basis of data consecutively read out from the memory.

  • Patent number: 5160799
    Abstract: There is provided an electronic musical instrument capable of sounding plural musical tones, e.g., first and second musical tones, having different tone colors, to each of which the performer can impart a different pitch-bend-effect independently. As a means for imparting the pitch-bend-effect, there is provided a wheel-type control. In addition, this system also provides first and second modes. In the first mode, different variation widths of pitch-bend-effects are respectively imparted to the first and second musical tones on the basis of the control input given by operating the wheel-type control. In the second mode, the same variation width of pitch-bend-effect is imparted to the first and second musical tones on the basis of the control input given by operating the wheel-type control.

  • Patent number: 5048390
    Abstract: A tone visualizing apparatus for visualizing an inputted audio signal to thereby display an image corresponding to this audio signal includes at least a detector, image display (such as a CRT display unit) and display controller. The detector detects characteristics of the audio signal such as envelope, chord, spectrum signal components, number of zero-cross points and energy of the audio signal. The image display displays an image based on given image information which can be generated from a video tape recorder (VTR), a video disk unit or an image memory constituted by a semiconductor memory. The display controller controls the image display so that a display parameter of the image will be controlled based on the detected characteristics of the audio signal. For example, the display parameter can be set as size, brightness or colors of the image. Thus, the image is controlled so that the impression of the image will be matched with that of the audio tone.

  • Patent number: 4916996
    Abstract: A musical tone generating apparatus utilizing a data compression method. A musical tone is sampled and is converted into waveform data. These waveform data are compressed into compressed data by a linear predictive coding method and further by a differential quantization method. The number of bits of each of the compressed data is thus significantly smaller than that of the waveform data. Thereafter, a memory stores the thus compressed data corresponding to an attack portion of the tone and a selected part of a sustain portion of the tone. Hence, it is possible to remarkably reduce the memory storage. When generating a musical tone, the memory reads out the compressed data of the attack portion and thereafter repeatedly reads out the compressed data of the selected part. The read-out compressed data are sequentially decoded into the original digital data. Thus, the whole waveform of the musical tone is reproduced.

  • Patent number: 4890527
    Abstract: There are provided first and second tone signal generation channels for respectively generating tone signals having waveshape characteristics corresponding to parameters assigned thereto. Tone color change control information such as key touch data is applied to a parameter assigning circuit. The parameter assigning circuit selects two parameters from among three or more parameters which are different from one another and assigns the selected two parameters to the first and second tone signal generation channels respectively. Tone signals having different characteristics, which are determined by the assigned parameters, are generated from the respective channels. The tone color change control information is further applied to an interpolation circuit connected to the first and second channels. The interpolation circuit interpolates the generated tone signals in accordance with the tone color change control information. A result of the interpolation is outputted as a tone signal for a tone to be produced.

  • Patent number: 4704933
    Abstract: The accompaniment apparatus for an electronic musical instrument comprises an accompaniment segment memory storing data representing a plurality of accompaniment segments which form a plurality of mutually different accompaniment patterns of predetermined lengths, and an alignment sequence memory storing, separately from the above, the orders with which these accompaniment segments are to be aligned sequentially. The data of these orders of alignment of segments are read out one after another, on the basis of which the accompaniment segments derived from the data of the segment memory are aligned one after another sequentially at a given tempo. This operation materializes the automatic accompaniment of any substantial length such as one whole piece of music, and allows the segment memory to have a capacity much smaller as compared to the case in which accompaniment patterns for the whole length of music have to be stored without skipping these segments of the same pattern.
