This way the audio is treated like any other input and you can mix it into the master audio or aux, which does get output to USB.The effects generator is a bit confusing to use, but thats likely just an issue with me the user, as I'm new to this.

and I love the way the documentation helps you decide how to setup your equipment for what you are trying to use it for

I use mine for podcasting as well as making informational CD's or MP3's
