Why using memory files? Such a thing is done automaticaly by mci controller:

So put on your form a TMediaPlayer from the component pallette and do this:

...
  MediaPlayer1.FileName := 'c:\test.mid';
  MediaPlayer1.Open;
...

... // when you want to start play
  MediaPlayer1.Play;
...

// if you want to continuously play the same file override notify event

procedure TForm1.MediaPlayer1Notify(Sender: TObject);
begin
  case MediaPlayer1.Mode of
    mpStopped : begin
                  MediaPlayer1.Rewind;
                  MediaPlayer1.Play;
                end;
  end;
end;


Ok?

Do the following:(We do need to use media player if you do not want to give over 500 points. Directly using MCI is not easy)

1 - Place the mediaplayer on form and set its Visible to false
2 - Change Notify property of MP to true
3 - Then when an action is taken the procedure I gave above is called. For example when MP is stopped mpNotify is set as the MP.mode and notify event is called.

Not satisfied? Please ask more.

If realaudio drivers (these are called CODECS and you can check them from ControlPanel->Multimedia->Devices->AudioCodecs tab). If there is a RealAudio codec there, then you can. Or you should install the CODEC yourself. The MCI can play the all files listed in Audio and Video codec sections includes. You should check the real audio site for CODECS. I do not deal with real audio but I am sure it has windows compatible codecs since Web browsers support it.
