简易电子琴演奏器的VHDL实现
本实验实现了简易的电子琴演奏，包括自动和手动演奏。
输入为BTN0~BTN6，代表1~7共7个音符。音高可切换低中高音，用两个拨码开关控制：“00”为低音，“10”或“01”为中音，“11”为高音。一个拨码开关切换收动/自动。一个开关控制存储（播放存储）/不存储。一个按键clr复位。
输出为8*8点阵、两个数码管（显示音高和字符）、蜂鸣器。
具体功能：
当切换至手动模式时，根据手动按键播放音乐并显示。此时若存储开关置1，当前播放音符被存储，采样频率10HZ。
当切换置自动模式时，播放系统自身存储的音乐。此时若存储开关置1，播放的是之前手动播放时存储的音乐。若再切换回手动模式，则音乐可以接上回位置继续往下存储。
当clr置1时，系统回到手动播放的等待状态，并将已存储的音乐清除。

Specific feature: When switched to manual mode, according to the manual button to play music and display. At this point, if the memory switch is set to 1, the currently playing notes are stored, the sampling frequency 10HZ. When the automatic mode switch is set to play stored music system itself.
