To use M1’s built-in auditioning player, you must have the drive/path/filename entered into the FILE field on the M1 cards. If you have the audio files tagged, then M1 can automatically import and update the data in the File field. This will work with .mp3, .ogg, .wma and other “tagged” audio files. .wav files do not have tags, so this mass-update can’t be done with files of that type. Contact the M1 support office if you want to get the proper data string into M1 for .wav files.
