19.1 Basic Concepts

Some synthesis techniques can be repeatedly extended to add additional complexity and tonal variation; for example, adding more sinusoidal oscillators to an additive synthesizer (Chapter 16), or more filters to a subtractive synthesizer (Chapter 17). Rather than considering how the underlying synthesis forms might be extended, it is often the case that blending the output of multiple synthesis sections in parallel (also known ...
