What App Works Well With Gb For Begginers? Options

[Pitchshifta]

I have been playing around with sounds apps like peak & sound edit for a few years, but at a am level because I would just modify sounds for flash & after effects. I am a graphic artist & video editor. I am starting to learn GB but I know I will have to use another app to add files or vocal tracks. Some people told me performer is the way to go, some say logic. My girlfriend & I want to craete some tracks if this helps. What do you guys suggest as far as software & method. Create loops in GB then import into another app to add vocal tracks & render? Does this sound like a good formula. thanks guys!
