Thanks! Taking the sound from the mic jack seems to work - though of course this is a real-time playback instead of just transfering a file. However, when i bring the sound into my Mac, i'm hearing a bit of static as well - and i don't hear this when i'm listening directly from the MD player through the headphones. Any ideas? I also take it that there's no way to convert the .hma files on a Mac to a more usable format, like .wav, .aiff or .mp3 ? Can you do this conversion on a PC and then bring it back to the Mac? Thanks again for your help. cheers, Michael
