The Design And Implemenation Of VSTi In Northern Shanxi Suona Plug

In the background of digital visual and auditory art, music production software platform,the host, the maturity is very strong, powerful, can completely virtual environment to produce complete and realistic symphonic classical, modern music. Mix the spurious with the genuine, fidelity and the degree of freedom is the original music production modecannot be mentioned in the same breath. But in the field of national music, because of itsrelatively plug-in peripheral support plug-ins is less, the quality is not high, from the surface to restrict national music development in the field of. However, in the Chinadomestic and all over the world, to China style, musical instruments China demand is more and more big, part of the film and television music directly with Western musical instruments to replace, music performance ability is severely restricted, Chinese musicelements of the "symbol" feature is not clear, give a person a kind of attempt an ineffective solution, the feeling, and folk music production, is restricted by. The digital construction of national music, national music development and the pace of Chineseculture to the world, and also is restricted. Development for Developing National Musicplug-in, is an imminent problem.VSTi Virtual Studio Technology Instruments abbreviation, It is Steinberg technologybased on virtual instrument, can be plug-in instruments, can also be effects, can also be a synthesizer. Basically in the form of plug-ins, can run on most of today’s professional music software.In this paper, the design and Realization of Northern Shaanxi suona plug-in as the research object, the first analysis of the necessity of Northern Shaanxi suona plug-in development, such as the use of perspective, compatibility, the feasibility of Instrument,flexibility, scalability, maintainability, security, easy operation, practicality, full consideration to the smooth transition to future technology and instruments products,memory management system platform has a high, full and reasonable utilization andapplication of memory space; and adapt to meet the future instrument samplingincreased growth requirements, instrument software engines with high scalability, it is convenient for users to upgrade the software, or add, Banhu, Ruan Sheng, keys etc. the new instrument. The focus will be on the design and implementation of the digitalinstrument suona Microsoft software, using MFC architecture, using studio 2010 as the development environment, using the Visual C++mfc object oriented developmenttechnology and advanced database management system SQL Server2010, design and implementation of development by making music and music editing business requirements for system. The main difficulty needs to consider the application of scientificinstruments, memory system and sampling accuracy sampling technology qualitymanagement.In this paper, the design idea of software engineering as a guide, from the overallanalysis, functional requirements, the principle of MIDI digital music synthesis and FM synthesis technology, system architecture design, functional design of audio plug-ins are studied and analyzed on the national musical instrument plugin. At the same time from the system function test, performance test and application aspects to explore the implementation process of the plugin.
