How do you add music? Every time I change the music number nothing happens. What am I doing wrong?

TO add music:

Get your track and name it background music x.mp3. The x is the number of the background music, and like Brell pointed out, you can't listen to it through the editor. Play the mansion with the game and you'll hear it. You won't hear it when you test in the editor. After you named it, go into the Midnight Mansion folder and go into the data folder. Go into music, and place the track in there. Name your track background music 5.mp3, if you don't have any more custom music in the folder.

While you're editing a room, go into Room Options (Command-L or in the File menu). Enter a number from 1 to 4 in the box that says Music Index, and then hit Save. You won't be able to hear the music while you're in the editor. Quit the editor, start up the regular Midnight Mansion program, and play your mansion. When Jack gets to the room you put the music in, the music should start.

If you still can't hear the music, check your options in the main game. Maybe you turned the music off at some point.

Remember, if you set the number to -1 no music will play. Also, when you're going into another section with different music, if you had music in the previous room you should set the music in the room before the new section to the current music playing, so if you go into the next section, music changes, then you go back to the old section for something, the music will change back to the old music that was playing.
