Okay, I'm a newbie to MD so bear with me... I have Sonic Stage 2.3 loaded and ready for use, but I have a few questions before I make my first transfer. My music library is all in MP3 format. I understand that in order to get it on the MD (MZ-N707) I have to convert to ATRAC, but I'd like to be able to convert only the files I'm transfering and then remove the .omg file from the hard drive once the transfer is complete. Is there a simple way to do this? Can I even do this at all? Thanks in advance for any help you can provide!
