A synthesizer is an electronic musical instrument that generates sound by combining and manipulating sound waves through a variety of techniques including subtractive synthesis, additive synthesis,
frequency modulation (FM), and wavetable synthesis. Synthesizers often feature a variety of controls, such as oscillators, filters,
envelope generators, and modulators, to allow for a wide range of sonic possibilities. Synthesizers are used to create both traditional instruments and unique, futuristic sounds.
