I've had this book for a few years now, and I'm not even close to tapping it out. It's well-written and detailed, and since it's not software-specific - it's universally applicable. I found it very helpful when first learning the fundamentals of synthesis, and now that I'm starting to learn Csound, I'll be reading parts of it again. There is so much information here, which makes it the kind of book you can grow into.The level of math is general enough for the attentive layman, yet not dumbed-down (I really should brush up on my trig, of course). If you want more detail on a subject, there are plenty of 'Suggested Reading' lists within. That's not to say the book skimps - it doesn't. I could go on, but a look at the Table of Contents says it better than I would.I'll admit, though - this book doesn't go in-depth on traditional analog techniques. I assume it wasn't meant to, given the title and abundance of analog synth books at the time of publication. This book will help you transfer analog techniques into the computer realm, but to learn those techniques in detail, you may want to supplement this with another - probably older - book.This book is essential. Of course, please don't buy it just to give it a one star because it didn't teach you how to use Fruity Loops - it's not that kind of "computer music" book. If you're genuinely interested in the subject matter, you won't regret owning it!
