Transfer to PC by USB using SonicStage3. A version of SonicStage should have come with your Hi-MD. If it's not 3, go to the Sony site to upgrade (free). In SS3, you can export to whatever folder you'd like in .wav, & then use any .wav editing program (Audacity, or non-freeware like Soundforge, Nero, etc.).
Good luck, and +t for your first show.
