Patent number: 7271330Abstract: 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.Type: GrantFiled: August 15, 2003Date of Patent: September 18, 2007Assignee: Yamaha CorporationInventors: Eiji Akazawa, Yasuyuki Umeyama

Publication number: 20070000371Abstract: Dynamics values are acquired intermittently at predetermined time intervals, and waveform data corresponding to the acquired dynamics values are acquired. The thus-acquired waveform data are synthesized to generate a tone waveform of a range corresponding to a sustain portion of a tone. Because waveform data to be used are acquired, from among a plurality of prestored waveform data for sustain tones, intermittently at predetermined time intervals in accordance with dynamics values and a tone is synthesized using the acquired waveform data, not only tone synthesis processing can be performed on a sustain portion of a tone, in accordance with the input dynamics values, with a reduced burden on a control section, but also the tone characteristic can be variably controlled in accordance with the input dynamics values. Thus, it is possible to synthesize a high-quality tone faithfully representing tone color variation such as that by a vibrato rendition style.Type: ApplicationFiled: June 30, 2006Publication date: January 4, 2007Applicant: Yamaha CorporationInventor: Eiji Akazawa

Publication number: 20060283309Abstract: 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.Type: ApplicationFiled: June 14, 2006Publication date: December 21, 2006Applicant: Yamaha CorporationInventors: Yasuyuki Umeyama, Eiji Akazawa
