From classic analog recreations to cutting-edge granular synth designs, these tools are crucial for sound design, songwriting, scoring, and live performances.
The beauty of today’s marketplace is the balance between free synth VSTs and high-end pro VST synth plugins meaning that no matter your budget, world-class sound is at your fingertips.
