multiplay tends to be rather picky about file format. It will
play some WAVs but not all, won't
play a bunch of file formats and codecs at all. It would be nice if he'd put up a list of accepted audio file parameters, but I haven't seen one. Would be REALLY nice to be able to
tie in some other codecs, not currently an option. You'll just have to make sure to save all files in a compatible format.
