What Is A Synthesizer VST Plugin?
A synthesizer is an electronic musical instrument that generates sound electronically using electronic circuitry such as oscillators and filters. It can imitate any instrument like a piano, flute, or violin and create its own unique sounds.
Most synthesizers generate sound using one or more oscillators, which are usually mixed together to create a timbre or tone. A synthesizer can produce a range of sounds, from realistic instrument simulations to non-natural sounds.
Having tested hundreds of free VST plugins, I can recommend these as some of the best free synthesizer VST plugins online.
