I just ordered a macbook with Logic Express 9. I'm new to the recording aspect of music even though i've been writing and having OTHER people record my music for 20 years plus. Aside from just the music gear, i.e. guitars, mic's, etc, what do I need to actually plug in and record? I have a berenger 4 channel mixing board; can I use that? If so, do I need anything additional to plug into the computer? What about powered speakers / monitors? If so, any recommendations (low cost) for home fun recording? I don't mean to sound so lame when it comes to this, but i'm new to the actual recording aspect. I look foward to any suggestions to help me in this new endeavor. Thanks.
