Player method for spurt tone in digital interface of musical instrument

Abstract

The invention discloses a method for playing a sudden sound in a digital interface of a musical instrument. In the method, a corresponding timing device is set for each channel in advance; property, generate an open channel event according to the property of the burst sound, and execute the open channel event, open the channel corresponding to the event, and play the burst sound on it; at the same time, the system will set the duration in the burst sound property to Send it to the timing device corresponding to the burst sound channel; when the duration ends, the timing device sends a closing instruction to the corresponding channel to close the channel. In the present invention, by setting a corresponding timing device for each channel, after the user generates a burst sound, the system controls the closing of the opened channel through the timing device, which solves the delay problem of burst sound playback and improves the burst sound quality. playback effect.

Description

technical field [0001] The invention relates to the technical field of musical instrument digital interface (Musical Instrument Digital Interface, MIDI), in particular to a method for playing sudden sounds in the musical instrument digital interface. Background technique [0002] MIDI is an international standard for digital musical instrument interface, which defines the communication interface between electronic music equipment and computers, and specifies the specification for using digital codes to describe music scores. [0003] The MIDI file itself is actually just a bunch of digital signals and does not contain any sound information. It just records which sound to play at what time and which sound to stop playing at what time. It is actually a set of sequence. When playing this group of tones, the system will play according to the on time and off time of each tone. Each sound corresponds to two events: open channel event and close channel event. MIDI sequence is a co...

Problems solved by technology

However, since the playback of burst sounds can only be performed sequentially, that is, the two events of the second burst sound can only be executed after the execution of the two events of the first burst sound is completed.

That is to say, when playing, the second burst sound must be played after the first burst sound has finished playing, which causes a delay in the playback of the second burst sound

The above is the delay caused for two sudden sounds, and for multiple sudden sounds, the delay will be more serious, which has a great impact on the playback effect of sudden sounds
