I have a Hi-MD recorder that I haven't had the time to start exploring yet. All I've managed to do so far was miss more than half of a good performance because I hadn't figured out how to record at slow speed! From my brief scan of the documentation, it seems that you can upload the recordings to the PC, and do some editing, but then you can only put them back onto a MD, and can't access them through any other program. More stupid marketing stuff.   

Speaking of stupid marketing stuff, is there a way of converting a WAV file into MP3? Or do I have to buy some expensive program to do it?

Aloha,
Mark
