GRM-tools Pitch Accum Effector In Electronic Music Works Sound Modulation Techniques In Sound Game

With the rapid development of electronic music since the 21 st century,the advances in technology have provided more possibilities for the creation of composers.More and more composers are committed to the development of sound materials for national musical instruments and apply them to electronic music,promoting the integration of national music and electronic music.The emergence of effects provides a better platform for the application of national instruments in electronic music.For example,GRM Tools is a plug-in-like sound processing software.In this paper,the Pitch Accum effects in GRM Tools are studied through periodic,random and comprehensive sound modulation techniques.In order to explore the acoustic effects produced by the three sound modulation techniques and the application in the work "Sound Games",choosing national plucked instruments,Pipa?Zhongruan?and Guzheng as sound materials,using experimental research and comparative research to explain the role of the modulation technique in the sound structure of the work.In this way,the modulation of the national instrument sound through the Pitch Accum effect to verify the structure division,image shaping,and language retouching of the electronic music works.The research of Pitch Accum effects provides more technical means for sound generation,a broader creative space for electronic music,a way for the research of other effects in GRM Tools and the application of traditional national musical instruments in electronic music offers more possibilities.
