Thank you for your response, jazzmammal. One can't be a music therapist without being a musician. Music Therapists use live music with their clients. I use BIAB to assist with song writing, as an "extra pair of hands" to supplement live music, to make practice tracks for students. Though BIAB may be available for Mac, Garage Band is not available for Windows users who are feeling left out. From what I've read here and in my research of both products, BIAB blows GB out of the water, but I don't know many therapists who are familiar with it. Hopefully, if my presentation is approved, that will soon change!
