补充说明：
这里的MIDI播放就是芯片内MIDI音源实时解码播放，不是录成WAV那种骗人把戏。
我们的MP2508是单芯片结构，打算拆FLASH存储器的就免了。

Product Description
VS1103 is a single-chip MIDI/ADPCM/WAV audio decoder and ADPCM encoder that can handle upto three simultaneous audio streams. It can also act as a Midi synthesizer.

VS1103 contains a highperformance, proprietary low-power DSP processor core VS_DSP4, working data memory, 5 KiB instruction RAM and 0.5 KiB data RAM for user applications, serial control and input data interfaces, 4 general purpose I/O pins, an UART, as well as a high-quality variable-sample-rate mono ADC and stereo DAC, followed by an earphone amplifier and a common buffer.

VS1103 receives its input bitstreams through serial input buses, which it listens to as a system slave. The input streams are decoded and passed through digital volume controls to an 18-bit oversampling, multi-bit, sigma-delta DAC. Decoding is controlled via a serial control bus. In addition to basic decoding, it is possible to add application specific features, like DSP effects, to user RAM memory.
