摘要:
Waveform data of a plurality of loop waveforms are prestored along with initial phase information corresponding to the loop waveforms. Two of the loop waveforms are selected and repeatedly read out to thereby form loop-reproduced waveforms corresponding to the selected two loop waveforms. These loop-reproduced waveforms are connected together, for example, through cross-fade synthesis, during which time the phases of the loop-reproduced waveforms are adjusted to match with each other using the corresponding initial phase information. Generation of loop read addresses is carried out in such a way that first and second address signals for reading out first and second loop waveforms, respectively, are caused to loop while maintaining a difference between the first and second addresses corresponding to a difference between the initial phases of the selected loop waveforms. With such arrangements, the loop waveforms can be smoothly combined together in a simplified manner without a need for prestoring waveform data in a previously phase-matched condition, and thus waveform formation rich in controllability and editability is achieved.

The present invention is directed to a system and method for providing a score window containing various types of execution icon layers onto which execution icons are attached and arranged in conformity with a progression of a musical tune on a screen of the display. In accordance with the preferred embodiment, each layer is controlled in response to various display commands. The system allows a user to select desired execution icons from an icon select palette that provides lists of execution icons which are registered in advance. Specifically, the user may select and “drag” an execution icon from the palette and place it at a position in correspondence with a particular point of progression of the music to be edited, causing the editing function corresponding to the execution icon to be effected at the point of progression of the musical piece. In accordance with the preferred embodiment, the execution icons are displayed by categories in accordance with a category display layer, which may be controlled to be displayed or not displayed in the editing screen.

Input waveform data are processed by Fast Fourier Transform or otherwise to separate a harmonic wave component from the waveform data while a non-harmonic wave component is separated by subtracting the harmonic wave component from the waveform data. Vector quantization is performed on the harmonic wave component by selecting and using one of prestored harmonic vectors as a representative vector for the harmonic wave component, and vector quantization is performed on the non-harmonic wave component, independently of the harmonic wave component, by selecting and using one of prestored non-harmonic vectors as a representative vector for the non-harmonic wave component. Then, using harmonic and non-harmonic vectors indicated by vector information of a waveform to be reproduced, waveforms of harmonic and non-harmonic wave components are generated separately and then combined to thereby reproduce/generate the waveform. The non-harmonic wave component is divided, on the basis of detected periodicity of the corresponding harmonic wave component, into a plurality of sections each having a length corresponding to an integral or fractional multiple of the period of the harmonic wave component.

A method of generating musical tones and a storage medium storing a program for executing the method are provided. Musical piece data is decomposed into phrases, the musical piece data being formed of pieces of performance data arranged in the order of performance. The pieces of performance data of the musical piece data are analyzed for each of the phrases obtained by the decomposing step. Tone color control data is prepared for each of the phrases according to results of the analyzing. The pieces of performance data of the musical piece data are reproduced by sequentially reading the pieces of performance data at timing at which the pieces of performance data are to be performed to the order of performance. Tone color characteristics of musical tones to be generated based on selected ones of the pieces of performance data which are reproduced by the reproducing step, are controlled according to the tone color control data prepared for ones of the phrases to which the selected ones of the pieces of performance data belong, respectively.

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 are attached and arranged in conformity with a progression of a musical tune on a screen of the display. The system provides an icon modify window that allows the user to modify parameters of a specific icon which is selected from among the execution icons attached onto the score window by double clicks of the mouse. Herein, the score window shows a part of a musical score (or a staff notation with notes), while the icon modify window shows an edited portion of the musical score by magnification, wherein a range of execution-related data being edited on the icon modify window is automatically indicated on the musical score of the score window. In addition, modification being effected on a note in the edited portion of the musical score is automatically reflected on note data and/or execution-related data in the performance data. The system also provides an icon select palette that shows latest selections of execution icons which are arranged in an up-to-date manner. The icon select palette shows a number of execution icons which the user frequently or lastly use. Thus, it is possible to improve performability and efficiency in editing performance data by using icons with simple operations and without errors.

A musical-tone-control apparatus having a baton which is provided with an acceleration sensor, and which is swung by a performer is provided. The intensity of a swing of the baton is detected by the acceleration sensor, and controls the tone-generation timing and tone elements such as tone pitches, tone volumes, or tone colors. The intensity of a swing is detected after a predetermined interval has elapsed from the beginning of a swing. As a result, a delay of detection of the intensity due to the inertia of the swing is eliminated. Hence, the swings and the tone-generating timing of musical tones are in harmony, which allows the performer to enjoy a natural feeling of performance.

A musical tone control apparatus has grips and elbow angle detectors, in which the grips are hand held and provided with push-button switches and an actuator, both of which are operated by fingers to generate musical tone control data having variations of musical tone. While the elbow angle detectors are provided with an angle detector for measuring an angle of the elbow during a performance, and generating musical tone control data with the variations corresponding to the angle of the elbow. Each variation is determined by function assignments which correspond to each of the fingers and elbows. The function assignments are preloaded in a memory device, such as a depth of vibrato, a speed of tremolo, a range of pitch-bend, and the like. Accordingly, the musical tone control apparatus transfers musical tone control data having variations to a musical tone generating apparatus to produce a musical tone from a speaker.
