As a professional, proficient user of other leading sequencers (e.g., Pro Tools, Cakewalk Sonar, and Cubase), I was very disappointed with Stephen Bennett's book "Making Music With EMagic Logic Audio".
The great majority of the book consists of laundry lists that provide only short descriptions of what various toolbars and buttons do--descriptions that are already available in eMagic Logic Audio's manual. The book fails to give us specific examples and walk-throughs to teach the various functions that are available in Logic.
The only chapter that is somewhat useful is the chapter on 'setting up an environment' in Logic. It does provide a step-by-step guide to setting up a simple environment. Unfortunately, it doesn't go into greater detail and covers only a small fraction of Logic's functionality. If you have multiple MIDI instruments, MIDI, audio and soundcards, this book won't help you set them up.
The remaining chapters are even more superficial, and provide laundry lists of Logic's functionality. But again, no walk-throughs or specific examples. Key features like Logic's audio tools are not covered.
I cannot recommend the purchase of this book.
