Abstract: Some of the repetitively generated impulse response signals are inverted for their polarities, and particular harmonics only are erased/attenuated. The rate of generating the impulse response signals remains constant or changes relative to the pitch, and the tones of the fixed formant type or the tones of the moving formant type are selected. Both ends of the impulse response signals are cut off, whereby the impulse response signals are superposed one upon the other in a decreased amount, and the amount of operation decreases. A plurality of impulse response signals are synthesized to generate impulse response signals different from the impulse response signals of before being synthesized. The rate of generating the impulse response signals changes not in proportion to the pitch, and tones of the moving formant type or generated changing more mildly than a change in the pitch.

Abstract: A desired tone signal is generated by the impulse response signals that are repetitively generated, and a tone is formed. Impulse response signals of a predetermined length corresponding to the frequency characteristics of the tone signal to be generated are repetitively generated. The recurring period of the impulse response signals repetitively generated varies depending upon a pitch-determining factor. The rate of generating the impulse response signals is changed depending upon a timbre-determining factor different from the pitch-determining factor, independently of the recurring period. Thus, the timbre of the tone signal formed from the impulse response signals is freely changed independently of the pitch.

Abstract: Automatic play progresses automatically with each sound generating operation based on timing data that indicates the timing for sounding a tone. In this manner, performance information for time count automatic play can be used with one-step automatic play. In addition, the information based on the tone generation operation for one-step automatic play and the information based on the sound generating operation for manual play are assigned to tone generating channels, which enables one-step automatic play and manual play to be performed together (in soli). Also, whether or not one-step automatic play is performed can be selected for each respective performance part or instrumental part.

Abstract: According to the invention, sound data is distributed as a plurality of sound data, and the distributed sound data are combined to obtain a plurality of synthesized sound data. The synthesized sound data are sounded by a plurality of speakers, thus forming a sound image. Through combining and multiplexing of sound data in this way, stereo sounds having a sense of spatiality are generated.

Abstract: Only in a transient band of a filter, substantially all frequency bands of the musical tone waveform are subjected to filter processing. Due to this, the drawback that the amount of change of the frequency characteristic of the musical tone gradually changes as a whole from a fundamental wave toward a harmonics and only one part of the frequency characteristic of the musical tone changes is eliminated.Also, the density of frequency components of the frequency band of the musical tone waveform does not change, the related frequency band is shifted in frequency, subjected to filter processing, and further shifted to a frequency in accordance with the musical tone pitch. Due to this, a specific range of the filter characteristic is selected, and the musical tone is subjected to the filter control only within this range.

Abstract: Early reflection sounds and subsequent reverberation sounds are processed in different modes by separate processing devices in order to obtain reverberation effects close to those of natural sound as well as to freely produce reverberation effects that do not exist in natural sound. When the early reflection sound overlaps the subsequent reverberation sound in time, the early reflection sound and the subsequent reverberation sound are produced without noise. There is no need to omit either one of them. Besides, complex envelope control is executed for the early reflection sound, and the envelope levels are weighted and fluctuated. Therefore, it is possible to establish a highly sophisticated sound field.

Abstract: A start portion of sampled sound data is cleared, and the resultant sound data free from the start portion is modified into data increasing gradually from level "0". Thus, noise in the start portion of the recorded sound data is removed, and also sound data gradually increasing from level "0" at the start can be obtained, that is, a discontinuous point after the noise removal is precluded.

Abstract: According to the invention, formant waveform signals which are waveforms synthesized from frequency components corresponding to formants of musical tones, are stored and read out or generated. When such formant waveform signal is read out or generated, the density of frequency components of the formant of the formant waveform signal is controlled and also the frequency of a formant center signal which is to be synthesized is a center signal with the formant waveform signal is controlled. In this way, the formant waveform signal is synthesized on the formant center signal. Thus, the density of formant frequency components and the formant center signal frequency can be controlled separately and independently. Further, the kind of formant waveform signal is switched according to musical factors of musical tone. Thus, different kinds of formant waveform signals to be output are switched according to musical factors of musical tones.

Abstract: Ratios of frequencies of frequency components of formant waveform signals are changed, and consonance of frequency components of a musical tone is controlled. Moreover, amplitudes, frequencies or numbers of formants are controlled depending upon the musical factors, making rich the contents for changing the musical tones.

Abstract: The content of component waveforms of at least one signal is changed in a variety of ways among the formant center signals that are synthesized with the formant waveform signals, making it possible to arbitrarily change the waveform of a musical tone that is generated. To cope with changes in the formant waveform signals Ffj(t) or the formant carrier signals Gj(t) formed by synthesizing the component waveforms, furthermore, the signals Fj(t) and Gj(t) are weighed and interpolated. This permits the signals Fj(t) and Gj(t) to change smoothly. Moreover, the number or combination of formant waveform signals synthesized to produce a musical tone is controlled depending upon the musical factors, elapsed time of sounding, envelope levels, envelope phases and/or settings instructed by an operator. This enables the form of the synthesized formant to be changed and the content of a musical tone that is generated to he changed in a variety of ways.

Abstract: A sound control device and method which increase the width of sound of sound data by controlling and outputting the phase of the sound data, in which the phase of the generated sound data is uniformly shifted over the entire frequency band of the related sound data and in which this sound data shifted in phase and the above described generated original sound data are output to different sound systems.

Abstract: A moment at which each of a plurality of pieces of sound data is generated in response to one sounding operation is controlled, and the plurality of pieces of sound data are output to different sounding units. Consequently, differences occur among moments at which sounds are radiated by the sounding units, resulting in an occurrence of differences among lengths of time taken by the sounds to reach the ears of a listener, whereby a stereophonic sound can be produced and the listener can localize a sound image.

Abstract: According to the invention, a plurality of pieces of frequency modulation information are weighted independently and then synthesized. The individual pieces of synthesized frequency modulation information are weighted independently, and individual pieces of sound data that have been generation speed controlled according to the individual pieces of frequency modulation information are synthesized. In this way, the individual pieces of frequency modulation information are weighted independently. Thus, the individual weighting processes may be changed in various ways without mutual restriction to produce for various changes in the frequency modulation.

To thus ensure an efficient use of the channels. Further, the predetermined number of channels to be assigned to any part of the piece of music can be ensured by assigning channels, other than the channels to be secured to newly performed musical tones.

Abstract: A device for use in an electronic musical instrument, in which a sound image is varied according to musical factors of musical tones. For example a sound image position, a number of sound images and/or a sound image shift pattern are varied according to a sounding order, a sound part, a tone color and/or effects. In this way, the sound image can be varied according to the contents of musical tones to realize play with a high spatial impression.

Abstract: Musical score can be displayed by a simple operation, thus permitting musical score to be easily seen when playing the music. Namely, musical score data of a plurality of pieces of music are stored in the musical score display, and when a piece of music is selected, the musical score data of this piece of music is read out and displayed, and thus musical score data can be easily selected and displayed. Musical score data that has been read out and displayed can be changed according to a feeding of a page. The displayed musical score, and the musical score page feed can be easily effected while playing the music. As a result, displayed musical score is changed according to a progress of a musical repeat for example Da Capo, Dal Segno, Al Fine, bis, etc.

Abstract: A waveform memory for storing data of musical tone waveforms can be mounted in and dismounted from an electronic musical instrument body. The waveform memory is thus replaceable, permitting the sounding of tones with various varieties. In addition, if musical tone waveform data corresponding to a tone designated for sounding is not stored in the memory, it is automatically loaded in the memory, thus permitting automatic sounding of tones to be requested.

Abstract: According to the invention, in response to a pause designation the operational status of sound generator or controller is stored, while at the same time the operation of the sound generator or controller is released. Thus, after the stopping of the autoplay, the sound generator or controller is released from the state that existed before the pause. It is thus possible to preclude continuous operation of the sound generator or controller, which is an undesired operational state.
