Beep不行，用API。引用：
Public Declare Function mciSendString Lib "winmm.dll" Alias
"mciSendStringA" (ByVal lpstrCommand As String, ByVal
lpstrReturnString As String, ByVal uReturnLength As Long, ByVal
hwndCallback As Long) As Long
例子：
  mciSendString "close
C:\Windows\Media\onestop.mid", vbNullString, 0, 0
  mciSendString "open
C:\Windows\Media\onestop.mid", vbNullString, 0, 0
  mciSendString "play
C:\Windows\Media\onestop.mid", vbNullString, 0, 0
