Synth VSTs are one of the most exciting things about being a producer today.
Powerful synthesis tools that used to cost thousands are now available in your DAW anytime, anywhere.
And the best part? Many of them are available as completely free plugins.
Software synthesizer plugins are great for everything from ambient pads to massive sub bass.
Hadron can be used as a synthesizer or an audio effect. It can also seamlessly morph between different sound processing methods, so you can make the plugin gradually change from synthesizer to audio processing mode. This is all part of the state morphing system, accessible via the big 2D joystick control.
In this article I’ll break down the top 8 free synth VSTs for producing music in your DAW.
Let’s get started.
