摘要： The present invention is directed to a waveform synthesizer apparatus that synthesizes a waveform of a musical sound based on musical performance event information. In particular, a music synthesizer includes an overlap detector that detects whether a first and second musical sound overlap, and a sound length meter that determines a sound length of the first musical sound. If the first and second musical sounds overlap, the synthesizer instantly terminates synthesizing of the first sound and starts synthesizing the second sound, provided the length of the first sound does not exceed a predetermined length. If the first and second sounds do not overlap, synthesis of the first sound is terminated, and the synthesis of the second sound is initiated, if it is determined that the length of rest between the two sounds does not exceed a predetermined length, and that the first sound does not exceed a predetermined length.

摘要： Either a tone generation priority mode or a quality priority mode can be set. If the currently-set mode is the tone generation priority mode when a connecting tone is to be generated for connecting between two successive notes, the joint-portion waveform data is selected for synthesis of the tone, stored head-portion waveform data and tail-portion waveform data are selected, and at least one of a pitch and amplitude of at least one of the head-portion waveform data and tail-portion waveform data is processed so as to provide a smoothly-varying connecting tone. In accordance with the processing, a tone of a fall portion of a temporally preceding one of two successive notes and a temporally succeeding one of the two successive notes are separately synthesized on the basis of the tail-portion waveform data and head-portion waveform data, respectively, so that a connecting tone is realized by a combination of the synthesized tone of the fall portion of the preceding note and the synthesized tone of the rise portion of the succeeding note.

摘要： A performance data editing system is actualized by a computer system (or electronic musical instrument) which is equipped with a display and a mouse. The system initially provides a score window containing various types of execution icon layers onto which execution icons (representing musical symbols such as bend-up/down, grace-up/down, dynamics, glissando, tremolo) are attached and arranged in conformity with a progression of a musical tune on a screen of the display. Each of the layers is independently controlled in response to various commands such as display-on, small-scale display, display-off and vertical rearrangement. The system allows a user (or music editor) to select desired execution icons from an icon select palette that provides lists of execution icons which are registered in advance. In addition, the system also allows the user to modify parameters of a specific icon which is selected from among the execution icons attached onto the score window. That is, the user opens an icon modify window to change parameters of the specific icon with the mouse. Further, the system provides the user with a simple operation for deletion of execution-related data from performance data. That is, when the user performs drag-and-drop operations on a certain execution icon to move it outside of a prescribed display area (e.g., layer window) of the score window, the system automatically deletes the corresponding execution-related data from the performance data. Thus, it is possible to improve performability and efficiency in editing performance data by using icons with simple operations and without errors.

摘要： Performance event data designating rendition style modules are supplied in order of time. When a given performance event data at a given time is to be processed in accordance with the supplied performance event data, another performance event data related to one or more events, following the given performance event data, is obtained in advance of a predetermined original time position of the other performance event daata. Control data corresponding to a rendition style module designated by at least one of the given performance event data and the other performance event data obtained in advance is generated on the basis of the given and the other performance event data, and a waveform corresponding to the designated rendition style module is synthesized on the basis of the control data. Characteristic of at least one of preceding and succeeding rendition style modules is modified on the basis of trailing end information of the preceding rendition style module and leading end information of the succeeding rendition style module. When rendition style designation data, including information designating a rendition style module and parameters for controlling the rendition style module, is lacking in a necessary parameter, the lacking parameter is filled with a predetermined standard parameter.

摘要： In a musical sound waveform synthesizer apparatus, a performance event information receiver receives performance event information representing musical performance events which successively occur as a musical performance progresses. A musical sound synthesizer synthesizes a waveform of a musical sound corresponding to each musical performance event based on the performance event information. An overlap detector detects whether or not a first musical sound and a second musical sound overlap with each other based on the performance information. A sound length meter obtains a sound length of the first musical sound based on the received performance event information. When the first musical sound and the second musical sound overlap with each other, the musical sound synthesizer instantly terminates synthesizing of a waveform of the first musical sound and starts synthesizing of a waveform of the second musical sound if the sound length of the first musical sound does not exceed a predetermined sound length.

摘要： Once performance event information is supplied in real time in accordance with a progression of a performance, a time indicative of temporal relationship between at least two notes to be generated in succession is measured on the basis of the performance event information supplied in real time. Comparison is made between a preset rendition style determination condition including time information and the measured time, and a rendition style that is to be applied to a current tone to be performed in real time is determined on the basis of the comparison result. With the arrangement that a rendition style to be applied to the current tone is determined on the basis of the comparison result, it is possible to execute a real-time performance while automatically expressing a tonguing rendition style.

摘要： In a memory, there are prestored shot-tone-related rendition style modules, each integrally including attack and release waveforms, in addition to attack-, release-, body- and joint-related rendition style modules. When two or more rendition style modules are to be time-serially combined, a shot-tone-related rendition style module is selectively assigned to a tone corresponding to a predetermined rendition style and allotted to a time axis. Then, a waveform is synthesized in accordance with the thus-allotted shot-tone-related rendition style module. Such arrangements permit production, with ample controllability, a high-quality waveform of a characteristic tone faithfully reflecting a predetermined rendition style having rendition styles of attack and release portions closely related each other, which was hitherto impossible.

摘要： In a storage section, there are stored special connecting waveform data for connecting between at least two notes to be generated in succession. The special connecting waveform data contain only a waveform of a succeeding-note region of a waveform connecting portion which is provided for a continuous transition between the at least two notes and which is divided into a preceding-note region and the succeeding-note region. When a connecting tone is to be generated for connecting between two notes in accordance with acquired performance information, a tone waveform connecting between waveforms of the two notes is generated using the special connecting waveform data. With such arrangements, the waveform data of the succeeding-note region are read out without waveform data of the preceding-note region being read out, so that it is possible to reduce a time required for transition from a preceding note to a succeeding note. Thus, in the connecting portion for continuously connecting between tones with no break therebetween, a tone can be synthesized with high quality without involving a tone generating delay in the succeeding note.

摘要： There is provided a rendition style selector operable by a user to select a desired rendition style from among a plurality of rendition styles associated with a plurality of portions of tones. In response to selecting operation via the selector, a rendition style is determined which is to be applied to each desired portion of a tone. Then, performance information is output which designates a rendition style module corresponding to the determined rendition style. The module defines a waveform characteristic to provide the corresponding rendition style. According to another type of the rendition style selector, a user can collectively select a combination of a plurality of rendition styles associated with different portions of a tone. Thus, a plurality of rendition styles can be designated collectively by one selecting operation. Rendition style suitable for each portion of a tone to be generated may be determined on the basis of a performance event.
