there's also 3 good basic textbooks on synthesis/sound design by Rick Snoman (Dance Music Manual), Martin Russ and Brian Shepherd that have specific recipes ("detune a saw and square by 3 cents...)
and if you don't have a synth, ask around for somebody that has Logic Pro X (several good synth models included) or Ableton with VST or AU's installed (you have to pay e.g. $100 for Analog unless you have Ableton Suite).
Since we're plugging stuff we like, ChucK co-author Perry Cook's book, here: http://www.amazon.com/Real-Sound-Synthesis-Interactive-Appli... is an excellent intro to DSP and synthesis techniques.
