多功能MIDI吉他效果器<br /> Multifunctional MIDI Guitar Effects Synthesizer<br /><br /> 摘要<br /> 本文设计和实现了一种基于ADSP-BF533的多功能MIDI吉他效果器。它具<br />有普通吉他效果器的音效功能，如失真，回响，颤音，均衡器，音量控制，<br />平衡控制等。此外它还具有节拍器，录音机，MIDI检测和合成，USB MIDI吉他，<br />U盘等特殊功能。MIDI合成功能具有128种旋律乐器，47种打击乐。节拍器内置<br />30种常用节拍。使用键盘操作，大屏幕LCD显示，人机界面友好。借助ADSP-BF533<br />的强大处理能力，很好的完成了以上功能。<br /><br />关键词：ADSP-BF533，吉他效果器，MIDI，USB。<br /><br /> Abstract<br />This paper describes the design and realization of a Multifunctional <br />MIDI Guitar Effects Synthesizer based on ADSP-BF533. It has audio effects <br />of traditional Guitar Effects Synthesizer, such as Distortion, Reverb, <br />Tremolo, Equalizer, Volume Control, Panning Control, and so on. Furthermore, <br />it has some specific function, such as Metronome, Recorder, MIDI detecting <br />and synthesizing, USB MIDI Guitar, U-Disk. The MIDI synthesizer includes 128 <br />melodic instruments and 47 percussion sounds. Metronome has 30 built-in common <br />rhythms. It has a good human-machine interface as a result of using the <br />keyboard and wide LCD. Due to the strong processing ability of the ADSP-BF533,<br />we have implemented aforementioned functions very well.<br /><br />Keywords: ADSP-BF533, Guitar Effects Synthesizer, MIDI, USB.<br /><br /><br />系统方框图：<br /><img src="https://bbs.21ic.com/upfiles/img/200711/2007112118442364.gif"><br /><br /><br />实物图：<br /><img src="https://bbs.21ic.com/upfiles/img/200711/20071121184921655.jpg"><br />
