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： Musical sound data derived from the musical instrument (1) is outputted via a capture filter (21), and effector filter (22), a flow-rate monitoring filter (23), and a renderer filter (24) to a speaker (3). The flow-rate monitoring filter (23) counts a buffer number nullCrnull under rendering process among a plurality of buffers 24a employed in the renderer filter (24), and then, feeds back this count result to the capture filter (21). The capture filter (21) deletes, or inserts data based upon this feedback information by way of an interpolation.

摘要： Style-of-rendition identification information representing a style of rendition of a performance tone is received, and reference is made to a predetermined table on the basis of the received style-of-rendition identification information to thereby obtain, from the table, style-of-rendition module data corresponding to the received style-of-rendition identification information. Waveform is produced on the basis of the obtained style-of-rendition module data. The style-of-rendition module data is data representing behavior of a waveform to be produced in accordance with a style of rendition and may include data representing characteristic behavior of vectors that control the waveform to be reproduced. The behavior of the waveform can be defined by various waveform factors. The vectors include, for example, vectors of various fundamental waveform factors for producing the waveform, such as a waveform shape, pitch, amplitude and time axis.
