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.
In this article I’ll break down the top 8 free synth VSTs for producing music in your DAW.
Let’s get started.
1. Digital Suburban Dexed
Dexed is a freeware FM synthesizer based on the legendary Yamaha DX7. It puts all the classic sounds and functions of the original synth in a modern package.
But Dexed makes classic 6 operator FM synthesis much easier to understand and program than it ever was with hardware.
This great free synth VST is perfect for percussive sounds like tines and mallets as well as icy pads or aggressive distorted basses.
2. Matt Tytel Helm
Synthesis is hard to understand even when you have real hardware synthesizer in front of you. It can be even more difficult when you’re working with an abstract software plugin.
That’s why Matt Tytel’s Helm is such a great synth VST.
Helm is a great sounding, two oscillator subtractive synth that’s dead easy for beginners to use.
It’s well laid out with a logical interface and helpful graphics that let you understand every aspect of basic subtractive synthesis.
Helm is perfect If you’re just getting started and need an easy synth to learn on.

4. DiscoDSP OB-Xd
Speaking of analog sound, DiscoDSP’s OB-Xd models one of the most sought-after instruments in analog synth history—the Oberheim OB-X.

6. Vember Audio Surge
Vember Audio Surge is probably the most powerful free VST synth on this list.
Surge is open source which means you’re free to download the code and do whatever you want with it.
It’s fantastic sounding digital synth that can cover all kinds of different sonic territory.
Its highly flexible architecture includes wavetable oscillators, two filters with eight different modes each and routing options for frequency modulation.
If you’re looking to get lost in the possibilities of sound design, Surge is the best way to do it for free.
7. VCV Rack
This next one is a little different, but it’s so exciting that it had to make it to this list.
VCV Rack is a standalone synth program that models nearly every module available for the Eurorack format.
That’s right—those enormous racks of modular gear that creative producers spend thousands of dollars collecting.
VCV Rack lets you create your own dream modular rig right on your desktop. You can even create patches authentically with virtual cables to get the real modular experience.
Integrating it with your DAW is a bit trickier—but using the plugin in standalone mode is just as fun for creating inspiring patches.
Every musician should try using VCV Rack to see what modular is all about.
