Let me amend that; if you make music with a DAW Buy "cakewalk synthesizers" now!
First off, I am a guitar player NOT a keyboard player. Oh my father tried to have me trained to play the piano, and I can still play blues solos in the key of C, but I never mastered the keyboard. I own several hardware synths but I have never been able to tweak the presets to create new or more appropriate sounds. Now I can! In "cakewalk synthesizers" Simon Cann walks you through the synthesis process, and has you creating and tweaking sounds right from the get go. The principles and techniques apply to any synth; hardware or software. Each of the synthesizers bundled with Sonar and Project 5 and CakeWalk's new stand-alone synths; Z3TA+, Dimension Pro, Rapture, are covered in great detail. The book alone is well worth the price of admission, but when coupled the downloadable chapters and content, buying this book is a no-brainer. If you make music in the digital world, you need this book! Every guitar player knows that his tone is his signature. Virtual instruments are here to stay and everyone producing music today needs to know how to take control of the tools of the trade. Why sound like everyone else when you can be creating your own signature sounds immediately.
