Add:

  • Missing MusicSequence.SetUserCallback method
  • Internal .ctor for MusicEventUserData which takes IntPtr

Questions:

  • Original MusicEventUserData has length and data. So users of the API can explore the contents of MusicEventUserData. In our version of API we also have both length and data but they're not exposed. Do you think we should make them available for the user?

var buffer = new byte[sizeof(int)];
Marshal.Copy (handle, buffer, 0, sizeof(int));
int length = BitConverter.ToInt32 (buffer, 0);

Can't this be replaced with this code?

int length = Marshal.ReadInt32 (handle);
