基于 Linux 与 VS1003 的 MIDI 电子节拍器的设计与实现，为乐器演奏（如钢琴、吉他）提供稳定，丰富，真实的基准节奏，可选择各种打击乐器组合的节奏型，设置节奏速度、节拍等。提供了 Linux 2.6 内核驱动程序和 Qt 4.4 开发的界面程序。系统可升级为 VS1053B 以获得更多的 MIDI 乐器音色支持，进一步开发支持 MP3、WMA、Ogg、AAC 等格式音频播放器，可录音，真正成为声乐练习的强力工具，更多信息请访问： http://sonew.512j.com/ 同时欢迎项目开发合作。-The design and implementation of MIDI Electronic Metronome based on Linux and VS1003. This provides the musical instrument playing (such as piano, guitar) a stable, rich and real rhythm. It can select the rhythm type by combination of variety of percussions, set the tempo, meter, etc. We gave the Linux 2.6 kernel driver and GUI program of Qt 4.4. The system can be upgraded to VS1053B to get more MIDI instruments’ tone support, and further developed to support MP3, WMA, Ogg, AAC format audio playing, recording and others, to be truly a powerful tool for vocal practice.
