| import javax.media.j3d.*;
import com.sun.j3d.utils.universe.*;
class TestSound
{
public static void main(String[] args)
{
String path = "file:myMusicFile.mid";
SimpleUniverse u = new SimpleUniverse();
u.getViewer().createAudioDevice();
MediaContainer media = new MediaContainer(path);
BackgroundSound sound = new BackgroundSound(media, 1, 10, false, false, true, new BoundingBox(), 1);
BranchGroup bg = new BranchGroup();
bg.addChild(sound);
u.addBranchGraph(bg);
}
} |
And i get this error:

It works perfectly with a
.au file but doesn't with midi ones. Have i missed something?
