I know this has been asked before, and the answers have all been 'but you are trying to convert from a protected format'.
But not in my case - I generated a MIDI file from a tune I input into Noteworthy Composer, converted to MP3 using Switch. The MP3 file is picked up by iTunes, and judging by the counter thingy at the top of the screen, is actually playing, BUT I GET NO SOUND!
HELP!
