A digital synthesizer is an electronic instrument that generates sound using digital signal processing. Unlike analog synthesizers, which create sound through voltage-controlled circuits, digital synthesizers use algorithms and computer-based techniques to produce a wide range of sounds. They can emulate traditional instruments or create entirely new sounds, making them versatile tools for musicians and producers. These synthesizers often come with various features, such as built-in effects, sequencers, and MIDI compatibility, allowing them to integrate seamlessly with other equipment. Popular models include the Yamaha DX7 and Korg Minilogue, which have influenced many genres of music, from electronic to pop.
