Hello all, I recently bought the H4N and I'm more than happy with it. It's just great but I have a doubt. I would like to record some songs (karaoke versions) but I can't find a way to play the song in the H4N while using headphones so the mic doesn't pic up the song, and, at the same time, record my voice on a different track. My idea is to have only my voice recorded on a wav file and match it with the karaoke song afterwards on my computer. Is this possible with the H4N or I need something like this: Amazon.com: Presonus AudioBox 22VSL 24-Bit/96 kHz 2x2 USB 2.0 Audio Interface: Musical Instruments ? Any help will be greatly appreciated PS. This questions is silly, I know, I tried to google the answer but couldn't get it. Thanks!
