Marking method for cross-track expression of electronic music score

Abstract

The invention discloses a marking method cross-track expression of an electronic music score. The marking method comprises the following steps: cross-track information in the music score is marked by use of extended events of an MIDI (Musical Instrument Digital Interface) protocol, the extended events of the cross-track information are marked, and when one MIDI note is deleted and the note has a related cross-track mark, the mark is searched and deleted simultaneously; the music scores containing the cross-track marking information are added, modified and stored in a standard MIDI file format, and MIDI events containing the cross-track marking information are transferred by use of a data structure compatible with the MIDI protocol; during MIDI transfer, the MIDI events containing the cross-track information marks are also transferred. The method is characterized in that the cross-track marking information for expressing inexpressible contents in the MIDI protocol is defined by extending the MIDI format, and the compatibility with the existing smart electronic music system architecture and the internet protocol is realized.

Description

technical field [0001] The invention relates to the field of intelligent electronic music systems, in particular to a marking method for cross-track representation of electronic music scores. Background technique [0002] At present, as a widely used music notation method, music scores represented by staves have been digitized in the publishing field. Notation software with different prices, positioning, and completeness of functions has enriched the choices of music lovers and publishers. Commonly used notation software on PCs include Lilypond, Overture, Sibelius, Finale, etc. These professional notation software are usually complex in function and bulky, aiming at exporting documents in formats such as PDF for printing, and converting typesetting instructions into private text or Stored in binary format for reading, modification and export. At the same time, most of these notation software supports MIDI format for exporting scores. [0003] Electronic musical instrument...

Problems solved by technology

However, the standard MIDI protocol cannot mark and display the cross-track information in the score. The display according to the standard MIDI events can only display the basic note information, and the display of cross-track notes will not be realized. Although the professional notation software can export MIDI files, However, on the one hand, the method adopted cannot match MIDI events with display elements for positioning, prompting and other operations, and cannot be combined with the functions of the intelligent electronic music system itself. On the other hand, the complex proprietary format and authorization also make it from There is a high threshold for transplanting PCs to embedded platforms, and the operating performance and efficiency cannot be guaranteed
