User chooses the melody file to be played, the melody from the bent storehouses of the MIDI in intelligent fender master controller Document parser is parsed to the melody file of selection, partial rail record note events and control event, is used as reference event The reference time that melody document parser is exported is reduced into staff and shown in the music score of Chinese operas by output to evaluator, performance evaluator is played Show in device and shown, each track correspondence a line staff；Meanwhile, when user is striked up by MIDI keyboards, intelligence electricity MIDI SEQ sequencers are received after the midi signal of MIDI keyboards output in piano master controller, and processing obtains the melody letter of user's performance Breath is as incoming event, and on the one hand output MIDI synthesizer into intelligent fender master controller is closed incoming event with source of sound Into pronunciation, on the other hand output, to playing in evaluator, is compared, passed through incoming event with playing the reference time in evaluator Note pitch parameter, note time started parameter, the note duration parameter for comparing incoming event and reference event are corresponded, is obtained Obtain evaluation result；When incoming event and reference time note pitch parameter, note time started parameter, note duration parameter it Between correspondence difference in the error range of setting when, be judged as correctly entering；When incoming event and the note sound of reference time Between high parameter, note time started parameter, note duration parameter correspondence difference in a certain item outside the error range of setting, or The incoming event with certain reference event same tone is not received in the error range of setting, then is judged as wrong input, and Display reminding is carried out in music score of Chinese operas display；When comparison obtains not having identical pitch between incoming event and reference event, then sentence It is disconnected to belong to erroneous input, not by carrying out display reminding in music score of Chinese operas display, but it is included in evaluation result.

A kind of described performance evaluator for intelligent fender, it is characterised in that：Play evaluator according to accuracy, Different classes of mistake and the statistics index pressed by mistake carry out integrating marking, and can individually list part index number and individually beat Point.

A kind of described performance evaluator for intelligent fender, it is characterised in that：For left and right in many track music scores of Chinese operas The note events of the identical pitch of hand lap, only to the time started, note is judged earlier, its result influence other with Overlapping note.

The present invention can be estimated to the music that user plays, and assessment result is shown by music score of Chinese operas display, and can Performance to user is given a mark, and improves the performance of intelligent fender, intelligent fender is possessed the function of music teaching.

Brief description of the drawings

Fig. 1 is intelligent fender theory diagram.

Embodiment

As shown in Figure 1.It is a kind of to be used for the performance evaluator of intelligent fender, by program construction intelligent fender master In controller, when user is played by MIDI keyboards, play evaluator and receive melody file solution in intelligent fender master controller The midi event of parser output is as reference event, and receives what MIDI SEQ sequencers in intelligent fender master controller were exported Reference event, incoming event are exported the music score of Chinese operas into intelligent fender master controller by midi event respectively as incoming event Display is shown, by the way that incoming event is compared with reference event, so that the performance to user is estimated, specifically Process is as follows：

User chooses the melody file to be played, melody file from the bent storehouses of the MIDI in intelligent fender master controller Resolver is parsed to the melody file of selection, partial rail record note events and control event, is exported as reference event To evaluator is played, play evaluator and the reference time that melody document parser is exported is reduced into staff in music score of Chinese operas display It is middle to be shown, each track correspondence a line staff；Meanwhile, when user is striked up by MIDI keyboards, intelligent fender MIDI SEQ sequencers are received after the midi signal of MIDI keyboards output in master controller, and the musical composition information that processing obtains user's performance is made For incoming event, on the one hand output MIDI synthesizer into intelligent fender master controller carries out synthesis hair to incoming event with source of sound Sound, on the other hand output, to playing in evaluator, is compared, by one by one incoming event with playing the reference time in evaluator Correspondence compares note pitch parameter, note time started parameter, the note duration parameter of incoming event and reference event, is commented Valency result；When right between the note pitch parameter, note time started parameter, note duration parameter of incoming event and reference time When answering difference in the error range of setting, it is judged as correctly entering；When the note pitch of incoming event and reference time are joined Number, a certain item outside the error range of setting, or is being set in correspondence difference between note time started parameter, note duration parameter Dull incoming event identical with certain reference event is not received in fixed error range, then is judged as wrong input, and in song Display reminding is carried out in spectrum display；When comparison obtains not having identical pitch between incoming event and reference event, then category is judged In erroneous input, not by carrying out display reminding in music score of Chinese operas display, but evaluation result is included in.
