Why won't Beatcraft play my audio file or use it as a drum track?

Certain audio files may be incompatible with Beatcraft. WMA files with Digital Rights Management protection cannot be used by Beatcraft. Also, WAV files that use certain forms of encoding or compression, such an uLaw or ADPCM, may not be compatible. Finally, corrupt or damaged files may be unreadable, or only partly readable, by Beatcraft.
