曲譜存貯格式 unsigned char code MusicName{音高，音長，音高，音長...., 0,0};?末尾:0,0 表示結束(Important)

音高由三位數字組成：

個位是表示 1~7 這七個音符

十位是表示音符所在的音區:1-低音，2-中音，3-高音;

百位表示這個音符是否要升半音: 0-不升，1-升半音。

音長最多由三位數字組成：

個位表示音符的時值，其對應關系是：

|數值(n):? |0 |1 |2 |3 | 4 | 5 | 6

|幾分音符: |1 |2 |4 |8 |16 |32 |64 ??音符=2^n

十位表示音符的演奏效果(0-2):? 0-普通，1-連音，2-頓音

百位是符點位: 0-無符點，1-有符點

調用演奏子程序的格式

Play(樂曲名,調號,升降八度,演奏速度);

|樂曲名?????????? : 要播放的樂曲指針,結尾以(0,0)結束;

|調號(0-11)?????? :?是指樂曲升多少個半音演奏;

|升降八度(1-3)?? : 1:降八度, 2:不升不降, 3:升八度;

|演奏速度(1-12000):?值越大速度越快;

以下為曲譜編碼文件，自己可以根據規則，對照簡譜編寫曲譜編碼表，我已經做好了一個應用程序，只需將簡譜輸入進去，就可以直接輸出曲譜編碼表，省去人工編碼的痛苦。此軟件作為共享軟件發布，在下面的鏈接可以下載。此東東絕對是搞電子設計在校大學生泡MM的巨佳手段，呵呵。
