Quantitative analysis of MIDI sequence editors for electronic music production

The rapid development of digital technology provides new tools and methods for electronic music creation. MIDI (Musical Instrument Digital Interface) sequence editor, as an important tool, is widely used in electronic music production. In this paper, the function, working principle and application value of MIDI sequence editor in electronic music creation are discussed by using quantitative and qualitative analysis methods. The research shows that MIDI sequence editor can input, edit and output music data by converting input signals such as computer keyboard and mouse into MIDI note signals. Its system model is composed of computer hardware (CPU, memory, sound card interface, MIDI interface, etc.), software (operating system, music synthesis software, MIDI device driver) and user interface (text box, button, slider, menu, canvas, etc.), providing users with a complete music creation platform. From the perspective of the development of electronic music, MIDI sequence editor not only supports different styles of music creation such as avant-garde electronics, electronic pop, electronic dance music, but also has powerful functions, including note input, editing, track creation, synthetic output, rhythm perception and effect processing. For example, it can identify the duration and spacing of notes, automatically set the beat point and adjust the duration of notes to enhance the sense of rhythm of music, while supporting volume, pitch, reverberation, echo and other effects processing, providing a rich means of expression for music creation. The results of quantitative analysis show that the electronic music composed by MIDI sequence editor has high sound quality (note matching degree of 82%) and real-time audio and video interaction ability (virtual instrument playing matching degree of 86%). In addition, qualitative analysis shows that MIDI sequence editor has the advantages of high flexibility, high accuracy, repeatable editing, visual operation and good compatibility. Users can easily create and edit various types of music works, achieve accurate control of music elements, and modify and improve them at any time. At the same time, its intuitive user interface and good compatibility also lower the threshold of music production. To sum up, MIDI sequence editor, with its powerful functions and advantages, has become an indispensable tool for electronic music production, providing efficient and convenient tools and methods for music creation. In the future, there is still room for further improvement in music expression, performance optimization, rhythm perception and effect processing.
