Embodiment
The present invention is a kind of personal adaptive MIDI playing system and method thereof, be to be applied on the executable MIDI player of computing machine to be used for playing the MIDI file, can be after the user adjusts the tone color in the MIDI file of specifying broadcast, further tone color in the whole music and parameter are carried out the processing of suitable propertyization, make the music of final broadcast have more harmony on the whole.
Referring to Fig. 1, personal adaptive MIDI playing system of the present invention comprises
According to the midi standard standard, form in MIDI file 10 roughly is divided into file header information (Header Chunk) and two parts of track information (Track Chunk), the file header information spinner will store the essential information in the MIDI file 10, as: each crotchet is cut into how much count (Tick), track information block counts, file layout code name ...; Then be used for storing a series of MIDI information as for track information, according to different file layout code names, MIDI information described here can be used for representing the MIDI information of single track (file layout code name 0) or a plurality of track (file layout code name 1), main system is basic as describing with file layout code name 1 among the present invention, and different MIDI information is distinguished according to different tracks by the MIDI information system under this kind form.
The front is mentioned through resolving obtained tone color and parameter, main system is at the part of MIDI information in the track information (TrackChunk), tone color and parameter are the main contents that constitute MIDI information, the musical instrument kind that will present when wherein tone color is equivalent to play, can use General MIDI (GeneralMIDI) tone color standard (having 128 kinds of different tone color definition) to be the definition source, but, also can use other to expand the tone color standard and be used as the definition source not as limit; As for parameter, then be to be used for the instruction that 120 pairs of tone colors of controls playing module play, comprise the parameter of pitch, loudness of a sound and audio frequency when being used for controlling tone color and playing at least, this part belongs to those who are familiar with this art can be known by inference easily, seldom gives unnecessary details at this.
Tamber data storehouse 130 is used for storing the tone color of various definition.As previously mentioned,, comprise 128 kinds of different tone colors in this tamber data storehouse 130 at least, also can store the tone color that to support different tone color standards according to the employed tone color standard difference of system of the present invention if with General MIDI (General MIDI) tone color standard.
Tone color adjusting module 150 is connected with document analysis module 110 receiving the whole tone color and the parameter of MIDI file 10, and when the user adjusts for tone color by control interface 140, carries out the replacing of tone color.
Suitable property adjusting module 160, be major technique feature of the present invention place, be used for after tone color adjusting module 150 is finished the tone color adjustment, whole tone color and parameter are carried out the processing of suitable property, comprise: at first generate parameter corresponding to new tone color, and then optionally carry out the handling procedure of changing all the other tone colors and parameter according to the tone color combination condition, perhaps optionally carry out handling procedure according to the parameter of adjusting back tone color and all the other tone colors of parameter correction, again produce new MIDI file then and starve whole tone color and parameter, be returned to document analysis module 110 again, deliver playing module 120 at last again and play according to the tone color and the parameter of new MIDI file.
The technological concept of suitable property adjusting module 160 proposed by the invention basically is that the tone color and the parameter that result from the original MIDI file 10 are through the resulting result of professional person's music; and when playing, can enjoy more various tone color variation in order to satisfy general user in the past; so can allow the user before broadcast, tone color to be adjusted usually; yet but ignored and other tone color and parameter between harmony; therefore the simple result who adjusts tone color will cause whole music to produce incoordination easily on playing, and this incoordination mainly comes from following several situation:
1, every kind of tone color all has its suitable corresponding parameters in theory, adjusts tone color and does not adjust parameter therefore merely, will cause parameter inharmonious when playing.
2, adjust single tone color, but produce make up with other tone color inharmonious.
3, adjust single tone color, though but with other tone color matched combined, but the pairing parameter of all the other tone colors still may produce inharmonious under through the prerequisite of revising.
Based on above-mentioned factor, if only providing the user to adjust tone color just directly plays, then the incoordination of whole music and result of broadcast are not good can be expected, therefore as long as the user has the tone color of carrying out adjustment, just must can guarantee the harmony and the result of broadcast of whole music through the processing of suitable property adjusting module 160.Will be in after a while by method flow and cooperate other graphic further specifying as for the suitable property processing procedure of in detail suitable property adjusting module 160.
In fact, in order to provide the user to carry out foregoing tone color adjustment and to play and set, can provide a control interface 140 usually outside Play System 100, promptly so-called user's operation-interface allows the user can carry out related setting.With Figure 4 and 5 is example, shown promptly is to carry out the signal that tone color is adjusted by control interface 140, show that in Fig. 4 tone color adjusting module 150 at the beginning receives the control interface aspect that is presented after the whole tone color of MIDI files 10 and the parameter from document analysis module 110, by among the figure as can be known each track (among the figure show this MIDI file 10 have three tracks) an independently control zone all can be arranged, at least comprise track title 290 in each control zone, as: theme music, accompaniment music, background music; Tone color district 291, be used for tone color adjusting module 150 is directly carried out the setting of tone color aspect, be to choose adjustment with the pairing musical instrument picture of tone color as showing for the user in control interface 140, this musical instrument picture can be stored in to be acquired when tone color is used in the tamber data storehouse 130 and be shown in corresponding tone color district 291; And broadcast setting district 292, being used to provide the user directly carries out setting as the broadcast of quiet, solo and volume to playing module 120, in fact design aspect the present invention of control interface 140 (containing the control zone) does not do any qualification, can or can provide the control order to carry out different designs according in fact different demands.And among Fig. 5, can find that then the tone color district 291 of theme music is adjusted into violoncello by original toy trumpet tone color, and show that the user has adjusted the tone color of theme music, therefore must carry out suitable suitable property processing at this tone color adjustment.
Referring to Fig. 6, the flow process of the specific embodiment of the invention is as follows: at first, resolve to obtain whole tone color and parameter (step 200) from Play System 100 external load MIDI files 10, this part mainly is to realize resolving by document analysis module 110 according to the format content that MIDI file 10 is had, and resulting tone color and parameter can be by the demonstration of control interface 140 dos as Fig. 4; Then receive all tone color and parameter by tone color adjusting module 150, do you and judge that tone color has adjustment? (step 210) be not if produce any adjustment, then directly entering into step 260 place will be in explanation after a while, when if instead tone color produce to be adjusted, then tone color adjusting module 150 can according to the selected tone color of user adjust the tone color of corresponding track and upgrade in the control interface 140 show state as shown in Figure 5; Enter into suitable property treatment step then, this moment will be by all tone color and the parameters (comprising the tone color that the user has adjusted) of suitable property adjusting module 160 catchers.
The suitable property treatment step of whole suitable property adjusting module 160 describes the suitable property adjustment model 300 of while with reference to figure 7.At first, we suppose that the user makes the action (being adjusted into tone color 8 by tone color 1) that tone color is adjusted to the track 1 of as shown in Figure 8 MIDI file 10, therefore through adjusting the action of tone color 400 behind the tone color adjusting module 150 to track 1, so (tone color 1 in the script track 1, parameter 1) can be adjusted to (tone color 8, parameter 1), all the other tone colors and parameter constant transmit all tone colors and parameter then and carry out suitable property treatment step for suitable property adjusting module 160.
At first, first step of suitable property processing is the tone color that the user adjusted to be carried out the adjustment of corresponding parameter at step 220 place, because previous tone color adjusting module 150 is only adjusted tone color, if corresponding parameter is not adjusted and probably can be produced inharmonious in the broadcast, therefore must adjust earlier the parameter of new tone color (tone color 8) at this, before the foundation of adjusting mainly is foundation, back tone color difference generates adjusted parameter, as shown in Figure 7, all tone colors 310 are divided into different classification 320 according to the tone color attribute in advance in suitable property adjusting module 160, tone color in different classes of 320 is set parameter basically and has in a way broadcast difference to satisfy the broadcast demand of different tone colors, with aforesaid adjustment tone color 400 actions is example, tone color 1 belongs to classification 1, tone color 8 belongs to classification 2, therefore suitable property adjusting module 160 can be adjusted the action of parameter 410 to adjusted tone color 8 when step 220, by among Fig. 9 as can be known the parameter that had of the tone color 8 in the track 1 this moment be adjusted to parameter 8 by original parameter 1.
After the completing steps 220, suitable property adjusting module 160 further enters into step 230 and judges whether all tone color combinations can produce inharmonic situation, this part mainly is to realize according to the change of the combination condition among Fig. 7 model 330, in this model, preestablish and be easy to generate inharmonic tone color combination condition, because each tone color 310 all has the classification 320 under it, therefore just can determine its tone color combination by 320 combinations of the classification under each tone color 310, be that prerequisite judges that all the other tone colors (tone color 2 and tone color 3) meet the tone color combination condition for not changing with the tone color 8 that the user was adjusted when judging? if meet then continue next step 240, otherwise then change all the other tone colors and parameter 420 according to the setting in the combination condition change model 330.With Figure 10 is example, can find to change by combination condition the condition of model 330 through the tone color 8 after the adjustment tone color and the combination of tone color 2 and tone color 3, therefore the action that must carry out all the other tone colors of change and parameter 420 is so that the requirement that the tone color of last integral body and parameter can meet harmony, combination condition change model 330 is tone color 4 and parameter 4 with the tone color and the parameter change of original track 2 in this example, with the tone color and the parameter change of original track 3 is tone color 5 and parameter 5, adjusts promptly directly to enter into step 250 after finishing and produce new MIDI file (comprising whole new tone color and parameter) again to deliver playing module 120 etc. for document analysis module 110 to be played.The part that produces the tone color change can show that the musical instrument picture of corresponding tone color supplies the user to know by control interface 140 equally.
If confirm the no inharmonious problem of tone color combination at step 230 place, then still must enter into step 240 place the parameter that all the other tone colors had is carried out the part correction, to improve the problem of disharmony that may exist.This part mainly is to realize by the tamber parameter correction model 340 in the suitable property adjusting module 160, establishes the corresponding relation between the different parameters in this model.The correction here mainly is according to adjusted tone color 8 of user and parameter 8, carries out the correction of the parameter of all the other tone colors.As shown in figure 11, after when in step 230, confirming the tone color combination no problem of tone color 8 and tone color 2 and tone color 3, just must carry out the action of the parameter 430 of revising all the other tone colors, the parameter of original tone color 2 is modified to parameter 2-1, the parameter of original tone color 3 is modified to parameter 3-1, make tone color 2 and tone color 3 can fully not be used the parameter 8 of the tone color 8 that the person adjusts, therefore can on whole music is play, reach harmony.Behind the completing steps 240, promptly enter into step 250 and produce new MIDI file (comprise whole new tone color and parameter) again to deliver playing module 120 etc. for document analysis module 110 to be played.
Do you judge that the user has by 140 pairs of broadcasts of control interface and set this moment? (step 260) do not obtained corresponding tone color and carried out the broadcast (step 270) of new MIDI file according to parameter according to resulting whole tone color if having then set with default broadcast in tamber data storehouse 130; If instead the user is correlated with to play and sets, then set and in tamber data storehouse 130, obtain corresponding tone color is carried out new MIDI file then according to parameter broadcast (step 280) with new broadcast.
At last, finish whole personal adaptive MIDI file playing process.Be noted that, the suitable property adjustment model 300 that the present invention is set up in suitable property adjusting module 160 mainly emphasizes to set up the suitable property adjustment model of a cover tone color combination and parameter combinations, the realistic model intension can be carried out suitable model adjustment according to the professional knowledge of being familiar with this skill person, not with exceeding described in this case.Those who are familiar with this art also can know by inference easily, when under some more complicated suitable property adjustment environment, this suitable property adjustment model 300 also can increase the consideration to different track weights, make the user when the tone color of different weight tracks and parameter are adjusted, can further have influence on the setting of all the other tone colors and parameter, make whole suitable property effect more remarkable, also this is not done any qualification at this.Therefore can all can suitably be increased in the suitable property adjusting module 160 as the factor that suitable property adjustment is considered such as, even make that finally can reach the general adjusted MIDI file of user all can present certain professional and harmony on final the broadcast.
