Abstract: Based on the understanding that time-varying characteristics of a tone element, such as an amplitude and pitch, in waveform data acquired through a live performance of a musical instrument include a variation component intended or controllable by a human player and a variation component not intended or non-controllable by the human player, the present invention allows the two components to be adjusted/controlled separately and independently of each other, so as to achieve effective and high-quality control. Discrete variation value train is acquired for at least one particular tone element in original waveform data, and the acquired variation value train is separated, in accordance with a time constant factor, into a “swell” value train of a relatively great time constant and a “fluctuation” value train of a relatively small time constant. The “swell” value train and “fluctuation” value train are variably controlled independently of each other.

Abstract: Non-linear functions to be used for automatically varying current values of parameters to be set, independently of each other, are prepared in corresponding relation to a plurality of parameter setting operator members, such as faders of a mixer. In response to an automatic setting instruction, such as a scene recall instruction, the current value of the parameter, to be set via each of the operator members, is caused to vary gradually toward a given target value with a characteristic based on a corresponding one of the non-linear functions. For example, the non-linear function is defined by a start offset for setting a delay in a start of the variation, and a fade time necessary for actually causing the parameter to vary up to the target value after the variation start. Processing of a predetermined type of event (e.g., GPI event) may be delayed to allow for a time delay that would result during execution of automatic setting processing of each parameter.

Abstract: Dynamics value is acquired intermittently at predetermined time periods, and a waveform data set for a sustain tone, corresponding to the acquired dynamics value, is specified from among waveform data sets stored in a memory. To generate a tone waveform while switching to the specified waveform, a waveform switching time is used which is modified suitably in accordance with a dynamics value variation amount from a predetermined time earlier than the current dynamics value acquisition time to the current dynamics value acquisition time. Such arrangements not only can variably control a tone, having a tone-color-variation realizing characteristic, in accordance with the input dynamics value but also permits a tone color variation with an enhanced responsiveness without causing the tone color variation to impart a feeing of undesired step-like unsmoothness, thereby synthesizing a tone with a high quality faithfully reproducing a desired tone color variation.

Abstract: A method is designed for controlling a total mixing system including a first mixing system and a second mixing system, which are operated in a linked manner. In the method, the first mixing system stores first scene data specifying contents of a mixing process matching a scene. The second mixing system stores second scene data specifying contents of a mixing process matching a scene. The first mixing system transmits a scene recall request to the second mixing system when a recall event of the first scene data occurs. The second mixing system transmits back a recall enabling response to the first mixing system after receipt of the scene recall request. The first mixing system reconstructs the contents of the mixing process on the basis of the first scene data after the reception of the recall enabling response. The second mixing system reconstructs the contents of the mixing process on the basis of the second scene data after the transmission of the recall enabling response.

Abstract: A method and apparatus implement time compression and expansion of audio data, with dynamic tempo change during playback. Dynamic changes in tempo are implemented at specific points in the audio signal corresponding to local minimums in the fade-in and fade-out characteristics of the compression/expansion scheme. An audio signal is marked to define temporal slices of audio data. Mark positions may be selected to minimize significant transient activity midway between consecutive marks. Fade-in and fade-out functions are associated with the leading side and trailing side, respectively, of each mark, creating a series of cross-fading “mounds” with peaks at each mark. When a tempo change is requested (e.g., a user selects a new tempo value in a user interface), the tempo change is delayed until the start of the next “mound” (i.e., the next fade-in). Thus, despite the tempo change, each mound uses a contiguous set of audio data, preventing the clicks and pops associated with skips in the audio’ data.

Abstract: Determination is made, in accordance with acquired performance information, as to whether a crossfade characteristic should be changed or not, and a crossfade characteristic of crossfade synthesis having already been started at the time of the acquisition of the performance information was acquired are automatically changed in accordance with a result of the determination. Because the crossfade characteristic is automatically changed during the course of the crossfade synthesis, the time length of the crossfade synthesis can be expanded or contracted as compared to the time length that had been preciously set at the beginning of the crossfade synthesis, and thus, the time position of a succeeding one of rendition style modules to be time-serially combined in accordance with the acquired performance information can be allotted to a time position displaced by an amount corresponding to the expanded or contracted time.
