Synthesizer basics
Synthesizer basics overview
If you are new to synthesizers, this appendix will help you understand the basics of sound
itself and how this applies to synthesizers.
Important facts about synthesizers are discussed and explained, including the differences
between analog, digital, and virtual analog synthesizers. You will also be introduced to
the major synthesizer terms as you learn about the basic workings of these hardware- or
software-based devices.
This appendix is not a detailed, scientific treatise on the inner workings and mathematical
theories of synthesis. It is a basic guide to what you need to know, including some extras
that are useful to know.
Experiment with the ES1, ES2, and other instruments while you read. Seeing and using the
parameters and other elements that are discussed will help you understand the conceptual
and practical aspects of synthesizers. See Logic Pro Instruments introduction.
Sound basics
Sound basics overview
Prior to considering any of the sound-generating components found in a synthesizer, it’s
important that you understand sound itself.
Technically, sound is the conversion of physical energy—such as a hand clap—to an air
pressure disturbance. This change in air pressure is transmitted as a series of vibrations—a
sound wave—through the air. Sound vibrations can also be transmitted through other
matter, such as a wall or floor.
