Sylenth1 is a virtual analog VSTi synthesizer that takes the definitions of quality and performance to a new level. Until now, very few software synthesizers have been able to match the sound quality standards of hardware synthesizers. Sylenth1 is one of those that do.
Sylenth1 isn’t just another synthesizer. It was built with a producer’s perspective in mind. It was created to create the highest quality sound and music. It was designed for performance. Extensive research was put into achieving an unknown warmth and clarity. The graphical interface provides the highest level of usability, allowing you to fully unleash your creativity.
