Qu Ku and music score of Chinese operas display form modules as two of smart electronics music system, in order to keep interconnected and to synchronize with other modules, and the agreement that also needs to take form that MIDI is compatible to input or output as it.But the MIDI agreement of standard cannot mark and show in music score across rail information, according to the event of standard MIDI, show and can only show basic note information, cannot realize the demonstration across rail note, although software can be derived MIDI file and specialty is set the chessman on the chessboard according to the chess manual, but the mode that it is taked on the one hand cannot be mapped midi event and display element to position, the operations such as prompting, cannot combine with the function of smart electronics music system itself, complicated privately owned form and authorize and also make that it is transplanted to embedded platform from PC and there is very high threshold on the other hand, and runnability and efficiency can not be guaranteed.

Summary of the invention

The object of this invention is to provide a kind of labeling method representing across rail for electronic music, be applicable to that MIDI edits, to what can not represent in midi standard agreement, across rail information, carry out mark, the problem existing to solve foregoing prior art.

In order to achieve the above object, the technical solution adopted in the present invention is:

A kind of labeling method representing across rail for electronic music, it is characterized in that: adopt the expansion event of MIDI agreement come in the mark music score of Chinese operas across rail information, expansion event is from being subordinated in logic a MIDI note event nearest before it, and expansion event and the before time difference of a nearest MIDI note event are 0; Mark is across the expansion event of rail information, expression be that the note event of its subordinate shows the not co-orbital same position from institute's mark, when deleting a MIDI note and note exist relevantly during across rail mark, search simultaneously and delete this mark; Employing standard MIDI file layout is added, is revised and stores the music score of Chinese operas containing across rail label information, in the inner employing of the smart electronics music system data structure compatible with MIDI agreement, come transmission package to contain across rail label information at interior midi event, while carrying out the transmission of MIDI between smart electronics music system, equally the midi event comprising across rail information flag is transmitted.

Described a kind of labeling method representing across rail for electronic music, is characterized in that: being used for mark can be the peculiar event of sequencer in metaevent across the expansion event of the MIDI agreement of rail information, can be also the exclusive event of smart electronics music system.

Described a kind of labeling method representing across rail for electronic music, is characterized in that: the MIDI note event being associated with expansion event can be that note starts event, can be also note End Event.

The present invention is by expanding midi format, defined a kind of for represent can not represent in MIDI agreement across rail label information, realized the compatibility with existing smart electronics music system architectural framework and interconnected host-host protocol, also be convenient to implement on embedded device, can resource-constrained in the situation that, complete music score demonstration in staff score across rail information, can fill up smart electronics music system and show to containing across the music score of rail information the blank of supporting, make based on smart electronics music system impart knowledge to students etc. operate more professional, practical.

Accompanying drawing explanation

Fig. 1 is that the present invention shows schematic diagram across rail information.

Fig. 2 be the present invention delete note operation to this note across rail Information Images result effect demonstration figure, wherein: Fig. 2 a shows figure for before deleting, and Fig. 2 b is for leaving out rear demonstration figure.

Fig. 3 is that MIDI data processing and data are transmitted schematic diagram.

Embodiment

Being used for mark can be metaevent (Meta Event across the expansion event of the MIDI agreement of rail label information, be designated as Meta) in the peculiar event of sequencer (Sequencer Specific Event, be designated as SeqSpec), also can be the exclusive event of system (System Exclusive Event, is designated as SysEx).The data of this event, with manufacturer's prefix beginning, remember that this prefix is MP, and mark is designated as TT across rail information.The mistiming of midi event, (Delta Time) was designated as xx, and MP and thereafter the byte total length of the data of following are designated as yy, and other data represent with the hexadecimal sequence of separating by byte.If except there being expansion necessary, can be after TT the format information of the serializing outside plus again, be designated as zz.The above expansion event format is as shown in table 1.Ensuing explanation is as the criterion and gives an example in SeqSpec mode.

Table 1 is used for the recording mode of mark across the expansion event of rail information

Method	Record form	MIDI protocol data
			SeqSpec method	xx?SeqSpec?MP?TT?zz	xx?FF7F?yy?MP?TT?zz
SysEx method one	xx?SysEx?F0MP?TT?zz	xx?F0MP?TT?zz?F7
			SysEx method two	xx?SysEx?MP?TT?zz	xx?F7MP?TT?zz?F7

Expansion event is from being subordinated in logic a MIDI note event nearest before it, and the time difference of these two events is 0.The MIDI note event being associated with expansion event can be that note starts event (NoteOn Event, be designated as NoteOn, the NoteOn that wherein dynamics is 0 expresses the implication identical with NoteOff), can be also note End Event (Note Off Event, is designated as NoteOff).The passage of note note event is c, and pitch is pp, and dynamics is vv, uses sexadecimal D1 to represent that, across rail information, the recording mode that can adopt is as shown in table 2 under protocol data standard.Ensuing explanation be take method one and is given an example as standard.Note decimally numeral of the lowercases such as " recording form " inner xx, pp, vv, " MIDI protocol data " is inner represents (the more than one byte of variable length integer possibility) with hexadecimal byte sequence; C is in " recording form " inner any one can be in tens digit 1 to 16, and in " MIDI protocol data ", corresponding hexadecimal digit 0 arrives F.

Table 2 is used for the recording mode of mark across the expansion event of rail information and the note event of its subordinate

Mark is across the expansion event of rail information, expression be that the note event of its subordinate shows the not co-orbital same position from institute's mark, as Fig. 1, increase after mark, can show the rail at same time note place.

When deleting a MIDI note, attached to rail label information if note exists, search and delete this across rail mark.As shown in Figure 2, when deleting the 11 brief summary note, system will be searched for, and delete that it is associated across rail information simultaneously.

Employing standard MIDI file (SMF) form adds, revise and store and contain the music score of Chinese operas across rail label information, in internal system, adopt the data structure compatible with MIDI agreement to come transmission package to contain across rail information at interior midi event, when the smart electronics music system relevant to system carries out the transmission of MIDI, by comprising these midi events across rail information, transmit equally, as shown in Figure 3.
