求翻译：在这科技飞速发展的时代，单片机的应用在不断的融入到我们的生活当中，推动了国内外科技的发展。在单片机的应用系统中，单片机往往作为一个核心的部件来使用，如果仅仅掌握单片机方面的知识还是不够的，应该结合具体硬件结构，以及针对具体应用对象特点的软件结合，加以完善。当今利用单片机控制的音乐播放多不胜举，音乐芯片也相当之多，而利用单片机存储音乐，控制播放最为广泛。它有功能多、价格优、外围电路简单的特点，很受音乐爱好者及音乐芯片制造商的青昧。在20年前诞生的MIDI无疑在电脑音乐的发展中起到划时代的重要作用，因此本篇论文是基于单片机并加入MIDI技术设计的音乐发生器，这比仅仅使用单片机和一些简单的外围设备设计的音乐发生器所产生的声音音质好，由于能力有限所以设计的是一种简单的音乐合成器。利用单片机和D/A转换技术来实现音乐的合成，由单片机片外扩展的一片2M的闪存来存储钢琴音效转换成的WAV格式文件，再通过单片机读取存储器中各个音效的代码送D/A转换电路进行转换，由喇叭来放出声音。本论文介绍了简单MIDI音乐合成器的硬件设计和软件设计的方法。硬件电路主要由STC12C5A60S2单片机芯片，FLASH ROM AT45DB161D芯片，D/A 转换器DAC0832芯片，按键电路和喇叭电路五个部分组成。软件程序部分采用的语言主要是C语言。是什么意思？

In this era of rapid development of science and technology, continues the application of single chip microcomputer integrated into our lives, promoting the development of science and technology at home and abroad. In single-chip microcomputer application system, SCM tends to use as a core part of, if only to master the SCM knowledge is not enough, should be combined with specific hardware and software combined with the characteristics of the application-specific object, be improved. Today with the single chip microcomputer control music playback many, chip music is very much, and using single chip computer stored music, control playback of the most extensive. It features multiple, excellent prices, characteristics of the peripheral circuit is simple, is very popular with music lovers and music blue chip manufacturer ignorant. In 20 years Qian was born of MIDI undoubtedly in computer music of development in the up to landmark of important role, therefore this article papers is based on single tablets machine and joined MIDI technology design of music generator, this than just using single tablets machine and some simple of perimeter device design of music generator by produced of sound sound quality good, because ability limited so design of is a simple of music synthesis Manager. Using single chip computer and d/a conversion technology to achieve the synthesis of music, by SCM chip scale of piano sound in a 2M Flash memory to store converted to WAV format files, then by reading the memory in each MCU code sent d/a conversion circuit for converting sound from speaker to emit sound. This paper describes a simple MIDI music synthesizer hardware design and software design method. Hardware circuit mainly by the STC12C5A60S2 microcontroller chips, FLASH ROM AT45DB161D chip d/a converter DAC0832 chip, press circuits and speaker circuit made up of five parts. Part the language is a c language software program.
