Perhaps it is a Sound Blaster thing, but I have given up on Creative Labs for several other reasons. Maybe it is coincidental with Windows 7, but I do not want to crawl under my desk, not purchase a Coaxial-SP/DIF device with another wall wort to record "What You Hear."

I use a Ketron SD4 for its great acoustic sounds, but also prefer RealTracks most of the time. Do the M-Audio Ultra FastTrack also serves as a mixer. It's control panel can be a little confusing, but once you get the software returns right it works with iSound7. I use Audacity as well as Sound Forge, and could not get both the External sound module and Real Tracks to record together. This program nails it.
