For this purpose, it can also includes Duration Information to play in indication signal, which is believed by terminal 1 according to the note in music score of Chinese operas data
Breath obtains, and terminal 1 determines Duration Information according to the time interval between the note in music score of Chinese operas data.Such as n-th in the music score of Chinese operas
Time interval between a note and (n+1)th note is 0.2 second, then for n-th of note, in the performance indication signal generated
Duration Information be 0.2 second.
Data processing unit 25 is remain on state according to the corresponding indicator light of Duration Information control and remains corresponding
Extinguish after time.
Such as terminal 1 can send out the performance indication signal of n-th of fa sound, the signal include strings of the Chinese zither number information be 003,
Indicator light number information 003a and 003b, 1 second duration then control after the data processing unit 25 of Chinese zither 2 is connected to the signal
Corresponding first indicator light of 3 strings and the second indicator light are persistently lighted 1 second simultaneously.As described above, also having between playing indication signal
There is interval time, interval time is not present with the duration to conflict, such as (n+1)th is played indication signal and referred to n-th of performance
Show that the interval time between signal is 0.5 second, the duration in n-th signal is then 0.5 second, then just at upper one
When indicator light corresponding to signal extinguishes, data processing unit 25 controls the corresponding indicator light of current demand signal and lights.
