摘要： A performance engine selects note patterns from a pattern style containing a plurality of note patterns. The note patterns are categorized by embellishment type and by ranges of playback levels. In addition, a beat pattern is specified for each note pattern, indicating the chord rhythm with which the style can be used. The beat pattern is a bit array, with bits corresponding to every beat of one or more contiguous measures. In response to selection of a particular embellishment type and playback level, the performance engine selects a note pattern that meets the following qualifications: (a) it is of the selected embellishment type; (b) its designated range of playback levels includes the selected playback level; and (c) its beat pattern indicates that it can accommodate chord changes at the beats at which such changes occur in the currently selected chord progression. If there are no qualifying note patterns, these conditions are gradually relaxed until at least one of the note patterns qualifies.

摘要： A system and a method for the notes of one track to move in a harmonically separate manner from the notes of another track when the notes of each track are played against a chord progression. Each track is associated with a chord function. The notes of the tracks are then played against a progression of polychords, where each polychord consists of one or more chords. In addition, each chord of a polychord is associated with one or more chord functions. During operation, each note of a track is mapped against a chord of the currently playing polychord. The chord for each track is selected by identifying the chord of the polychord that is associated with the same chord function as the track. Furthermore, individual tracks, groups of notes, or single notes can be assigned to one of several playback modes. Each note includes a field that identifies a playback mode. In addition, each track is associated with a playback mode. Prior to generating a performance note, the playback mode for the note is determined, and the note is transposed or mapped against the currently playing chord in accordance with the playback mode.

摘要： The present invention provides a system and a method for intelligently controlling note inversions during a computer based musical performance. During a musical performance, notes of a track are transposed against a chord. In some instances, the resulting pitch of the transposed note may fall outside of an upper-pitch boundary or a lower-pitch boundary defined for the track. Two additional control mechanisms are examined to determine if the note should be inverted. One mechanism includes a chord inversion mask used for managing the inversion of notes within the context of the chord. Another mechanism includes a track inversion mask defining one or more series of ranges where inversions are allowed. If the pitch of a transposed note exceeds the upper-pitch boundary or the lower-pitch boundary, the chord inversion mask and the track inversion mask are scanned to determine if the note can be inverted. The scanning process includes looking at each position in the chord inversion mask and the track inversion mask between the exceeded boundary and the pitch of the transposed note. If a position is found in which the chord inversion mask and the track inversion mask allow inversions, then the note will be inverted.
摘要翻译：本发明提供了一种用于在基于计算机的音乐表演期间智能地控制音符反转的系统和方法。在演奏中，轨道的音符与弦并列。在一些情况下，所转移的音符的所得音调可能落在为音轨定义的上边距边界或下边距边界之外。检查两个附加的控制机制以确定音符是否应该反转。一种机制包括用于管理和弦上下文中的音符反转的和弦反转掩模。另一种机制包括定义允许反转的一个或多个系列范围的轨道反转掩模。如果转置音符的音调超过上边距边界或下边距边界，则将扫描和弦反转掩码和轨道反转掩码，以确定音符是否可以反转。扫描过程包括查看和弦反转掩模中的每个位置以及超出的边界和转置音符的间距之间的轨道反转掩模。如果找到一个位置，其中和弦反转掩码和轨道反转掩码允许反转，则音符将被反转。

摘要： A method of generating music includes steps of specifying a note sequence and a chord progression against which the note sequence is played. The notes of the note sequence are defined relative to chord elements, and melodic runs are identified within the note sequence. Each melodic run consists of a series of notes. Inversion conditions are specified in terms of inversion boundaries and in terms of legal inversion notes relative to the individual chords of the chord progression. When interpreting the note sequence in conjunction with the chord progression to generate output notes, the output notes are compared against the inversion conditions and inverted if appropriate. If a note belongs to an identified melodic run, the run is evaluated against the inversion conditions as a whole. More specifically, one note of the melodic run is compared against the inversion conditions. If the one note satisfies the inversion conditions, the entire run is inverted. If the one note does not satisfy the inversion conditions, none of the notes of the run are inverted.
摘要翻译：产生音乐的方法包括指定音符序列和音符序列播放的和弦进行的步骤。音符序列的音符相对于和弦元素定义，并且音符运行在音符序列内被识别。每个旋律都由一系列音符组成。反转条件是根据反转边界和关于和弦进行的各个和弦的合法反转音符来规定的。当将音符序列结合和弦进行解释以产生输出音符时，将输出音符与反转条件进行比较，如果适当，则将其反转。如果音符属于识别的旋律曲线，则运行将根据反演条件作为整体进行评估。更具体地说，将旋律跑步的一个音符与反转条件进行比较。如果一个音符满足反转条件，则整个运行反转。如果一个音符不满足反转条件，那么运行的音符都不会反转。

摘要： A musical performance is generated by a segment object and a plurality of constituent track objects. Multiple segment instances can be played concurrently by instantiating multiple state objects corresponding to the segment instances. Each state object stores state information for the track objects of the segment object. When calling a track object to play a portion of its track, the state object provides the stored state information and the track object plays in accordance with the provided state information. The track object updates the state information and returns it to the segment object. Each state object calls the same track objects, but maintains a different set of state information for use by the track objects. This allows multiple concurrent instances of the tracks, without requiring actual duplication of the track objects.

摘要： A music generation system includes a segment manager and a plurality of segment objects. Each segment object has one or more track objects. Each track object containing a time sequence of musical performance data. Some of the track objects are dependent track objects and some of the track objects are controlling track objects. The dependent track objects contain dependent musical performance data that is interpreted based on controlling musical performance data contained in one or more of the controlling track objects. Each of the controlling track objects contains a predefined type of controlling musical performance data, wherein a plurality of different control type identifiers correspond respectively to different predefined types of controlling musical performance data. When a dependent track object needs controlling musical performance data, the track object calls the segment manager with an argument comprising a control type identifier. The segment manager responds by calling one or more segment objects with arguments that include the received control type identifier. In response a called segment object identifies one of its track objects that contains the requested type of controlling musical performance data and returns the musical performance data from the identified track object to the segment manager.

摘要： A music generation and playback system includes an application program and a music processing component. The application program makes repeated calls to the music processing component and provides a group of music events to be sent to the music processing component during each call. Each group of events comprises a plurality of individual events and associated timestamps indicating when the events are to be played. The timestamps of the individual music events of a particular group indicate that the events are to be played at varying times subsequent to being sent to the music processing component. The music processing component exposes a latency clock interface, which indicates the earliest time at which a new music event can be rendered. The application program uses this interface to determine how far ahead of time to provide new music events, and to schedule spontaneously occurring events for playback at the earliest possible time.

摘要： The invention utilizes segments and tracks to generate and playback musical performances. A segment is implemented as a programming object, and represents a specified musical piece. The segment comprises a plurality of tracks, each of which is implemented as a programming object. The tracks are of different types, and generate music in a variety of ways. However, every track supports an identical track interface that is utilized by the segment object. To play the musical piece, a performance supervisor makes repeated calls to the segment object to play specified intervals of the musical piece. In response, the segment object calls its track objects, requesting them to play the specified interval. The tracks generate the requested interval in accordance with their own methods. In some cases, the track objects communicate and cooperate with each other to generate their musical tracks.

摘要： The present invention provides a system and a method for tracking parameters of a synthesized �an! audio signal that reduces the amount of processing time without causing any discernible degradation in the sound quality of the audio signal. An audio signal is intelligently divided into multiple time slices and the parameters of the audio signal are tracked over the duration of the time slice. The time slices are selected so that the actual characteristic of the parameters over the duration of the time slice can be easily approximated by performing simple, non-processor intensive steps. The characteristics of various components of an audio signal such as a volume envelope, pitch envelope, low frequency oscillator, MIDI commands controlling the audio signal, and various other inputs are used to identify control points. Adjacent control points are then selected as the start point and end point of a time slice. Absolute values for the start point and the end point of the time slice are used to determine a step duration and a step delta. The parameters of the audio signal are tracked by using the absolute values for the start point of the time slice to generate initial control signals for the audio signal at the start point of the time slice. Then, the control signals are modified by the step delta at every step duration to the end point of the time slice.

摘要： The present invention includes a system and a method for a series of discrete MIDI events to be represented by a single curve event. The curve event is stored as a curve data structure and may include one or more sub-curve data structures. Each sub-curve data structure represents one or more of the series of discrete MIDI events. The curve data structure identifies when the curve event should start, the type of MIDI events that the curve represents, and a list of one or more sub-curve data structures. Each of the sub-curve data structures identify a curve-shape, the start time for the playback of the sub-curve, the end time for the playback of the sub-curve, the minimum and maximum values that the sub-curve reaches, and an orientation of the sub-curve. At performance time, each sub-curve event in the curve data structure is converted into time-stamped, discrete MIDI events that can be provided as input to a MIDI device. This is accomplished by, for each sub-curve identified in a curve structure: (1) establishing the starting point of sub-curve; (2) establishing the value for the first MIDI event; (3) establishing the ending time of the sub-curve; (4) establishing the value for the last event; (5) generating a series of MIDI events between the first and last MIDI events.
