Filed: 2006-02-20
Abstract: Method for automated control of time of reproduction of musical composition relates to electronic musical instruments, in particular to methods for control of parameters of reproduction, and can be used in musical computer systems for accompaniment. The method includes formation of data basis of musical compositions that include parts of soloist and accompaniment, choosing needed musical composition. Additionally one obtains graphical representation of chosen musical composition with transformation of chosen musical composition to MIDI equivalent agreed in time with graphical representation. Besides that one sets time criterion for synchronization of soloist’s party and accompaniment, with implementation of search of synchronization points in MIDI equivalent of musical composition between soloist’s party and accompaniment with account of time criterion of synchronization. One performs segmentation of MIDI equivalent of musical composition by points of synchronization found with separation of introduction and end of musical composition. In segments of MIDI equivalent of musical composition left one determines guide points with account of time criterion of synchronization. At reproduction of musical composition one performs correction of time of reproduction in synchronization points and in guide points. Technical result is in high accuracy of reproduction of musical composition due to synchronization of soloist’s party and accompaniment.
