The 22 Best Free VST Instruments (2021)

In this list we are gonna go over the best free VST instruments with those for a budget. All these have the best price which is free.

First we need to clarify a difference to avoid a confusion about this list.

VST Instruments: This is all the virtual synthesizers or instruments samples that produces audio. Examples can be FM synthesis, pianos, rhodes, strings, guitars. So this is what this list is about.

VST audio effects: These affects the sound of the audio and changes it in someway. Examples is reverb, delay, distortion, compression.

All these are free with optional to donate to the developer. So without further ado let's go.

1. VITAL Spectral warping wavetable synth

vital best free vst instrument

This is by far the most insane synth that is free. Many call it the Serum killer which I don't agree with completely, both is great synths but that shows what quality of a synth this is.

It's like Serum and Phase plant had a baby.

This is a synth that has spectral warping wavetables, LFO's (you can modulate everything drag & drop), FM, tons of filter options with really high-quality clean oscillators.

Has it's own effects tab to process your sounds with multiband compression (really similar to OTT), delay, reverb, phasers and much more.

It has a text-to-wavetable feature which means you can type any words and it'll generate a wavetable you can scroll through to make the synth talk, really unique.

The scalable interface is really intuitive and FUN to use. 

Could talk forever about this synth, the free version is the full synth with almost no limitations.

Also check out my Lofi essentials preset pack for vital to get even more presets.

2. Komplete Start (Native Instruments)

And you get some cool audio effects including guitar rig 6 player for guitar amp simulations.

7. Zebralette

Zebralette u-he

Again from same developer we have Zebralette which is like a stripped down version of it's big brother synth Zebra2.

But it's still a powerful synth with 300 factory presets. It has only one oscillator but it has waveform editing to make your own waveforms and four drawing modes geomorph, spectromorph, geoblend, spectroblend.

Which basically means you can morph and blend between the different waveform shapes to create unique sounds.

Bundle that up with 24 spectral effects like filters, phase distortion, 2 lfo's and you'll have a really solid synth to play around with.

Zebralette available on Mac, Linux & PC


helm synth

Helm is a free open-source synth made from the same developer on Vital (Yes one person, so talented!).

This synths has it all, everything in one place can look a little messy but it works fine.

2 oscillators + 1 sub oscillator, a filter to morph between HP, BP, LP much like in Vital. 3 LFO's with multiple shapes, 32 Step sequencer, distortion, arpeggiator ,delay and reverb.

Over 200 presets included and it's feels like a early version of Vital.

HELM available on Mac, Linux & PC

9. DSK Virtual Instruments (Guitar, Music Box, Saxophone)

dsk dynamic guitars vst

DSK music has some good sampled instruments available on their website you can check out but I chose three i particularly liked.

DSK Dynamic Guitars: 3 Different guitar types: Nylon, Steel & Acoustic. Simple ADSR control with reverb and pan. But with the range knob you can chose how it reacts to how hard you hit the keyboard (velocity). So there are different samples depending how hard you play, so playing softly has a soft sounding guitar sample etc.

DSK SaxophoneZ: 3 Different saxophone type: soprano, alto, tenor. What's good with this one is that when you hold a note longer it has a vibrato effect like a real one. Aka making the pitch slightly go up and down not just a straight note.

DSK Music Box: Simply a good clinky toy music box, no settings just open and go.

Dsk instruments available on Mac & PC

10. VSCO2 Orchestra

VSCO2 Orchestra vst flute

VSCO2 Orchestra has a rompler with over 2000 samples recorded for over 25 instruments. 

All instruments are in one plugin so you can simply use the dropdown menu by clicking instrument name to choose one. It has all kinds of instruments such as clarinet, harp, marimba, flute, tuba and more.

Kinda basic feature with just ADSR, pan and a reverb.

Not as good if you wanna make a real sounding orchestra with expensive sound libraries, but it's good value for being free and definitely worth checking out.

VSCO2 Orchestra available on Mac & PC (VST or .NKI Kontakt)

11. Dexed FM Synth

dexed fm synth

Dexed is a free open source synth that is closely modeled after 80's analog Yamaha DX7 synth.

Can be a bit daunting as the HELM synth where everything in one place but if you look there are six oscillators where each has it's own "block", if you think like that it's a bit simpler.

At the bottom is also where you have the frequency modulating with different algorithms you can choose.

Great for retro sounds such the 80's FM sound and comes with over 1000 presets.

Dexed available on Mac & PC

    It comes with a built-in 808 kit such as kick, snare, hi hats, toms and so on but you can also import your own drum samples and from there you can shape them how you want.

    Not technically a synth or instrument but worth a spot.
