Recording Some Improvisation

I finally got my studio set up in a way that makes it much easier to do things!!!! Yay!  I began recording an improvisational piece using only the Fusion tonight.  It is a total sound out really.  I've done a lot of internal synth work using Logic's AU, but I've not done much audio recording into it.  I need to do some investigating on sound levels and what not.  The new controller will have a preamp and be an audio hub so I am hoping I will be able to use that to cut down on hiss - I don't like unintentional hiss.
