Hi Chemishev,
I currently teach music synthesis at several colleges near Sweetwater, and at Sweetwater U. Prior to that, I was an Associate Professor of Music Synthesis at Berklee College of Music. I always recommend:
Power Tools for Synth Programming
http://www.amazon.com/Power-Tools-Synthesizer-Programming-Reference/dp/0879307730#
It was written by Jim Akin, who was Editor-In-Chief for Keyboard magazine for many years. And, since I was hired to be the proofreader for this book before its publication, I can definitively say that I fully agree with everything that’s in the book. 
It’s reasonably priced and, because it’s a college text book, you can often find a used copy for even less.
It also comes with an audio CD of sonic examples of what each section is discussing.
