It’s been a while since I surveyed the market for free software synths, so I thought I’d give it go and see what’s new and what has stood the test of time. Some of these instruments were released as prototypes or were the early experiments of developers just entering the market.

Free stuff is not always actually free. Often you will follow a link only to find out that it’s a free “demo”. Aren’t all demos supposed to be free?? In other cases, free software is dangled like a carrot in order to get your email address or to entice you into buying other products, preset libraries, add-ons, etc.

Well, business is business, and I suppose everyone needs to make a buck. I really don’t mind spending a few dollars for some shareware now and again to support a budding developer. But it behooves even the most experienced consumer to proceed with caution when the word free is thrown around.

What follows are some awesome sounding instruments in no particular order that are indeed free with very few strings attached. And if you can stomach a little extra spam, some of these may prove valuable additions to your stockpile of synths.

1. TyrellN6 by u-he

Virtual analog with classic architecture, plus extras.
Two oscillators, noise, ring modulator.
Two LFOs with eight waveforms that are host-syncable.
Audio source mixer with authentic overdrive and filter feedback.
Twin filter related to Diva (early model).
Unison with up to eight voices.
Analog-type ADSR envelopes, loopable or LFO-triggered.
Small modulation matrix with depth modulation from a second source.
Chorus effect with three modes.
MIDI learn / unlearn for hardware control.
Resizable UI from 70% to 200%.
Skinnable UI.
Over 580 factory presets.

This thing is responsive as hell and sounds sweet! I love the stained and grungy aesthetic of the interface. It’s really hard to believe it’s free. But it serves its purpose I suppose because it truly whets the appetite for more stuff from u-he.

2. Dexed

Dexed is an emulation of the classic FM synth: Yamaha DX7.

From the Github page:

“Dexed is a multi-platform, multi-format plugin synth that is closely modeled on the Yamaha DX7. Dexed is also a midi cartridge librarian/manager for the DX7. Do not expect this to be a perfect clone of a DX7 since this will take years in the open source world and multiple collaborators before getting there … Since Dexed is modeled on the DX7, the Yamaha DX7 Operating Manual can be used as a reference documentation.”

The interface is a little cluttered and is more functional than it is aesthetically pleasing, but there are a ton of sonic possibilities with this for those willing to dig in.

3. MiniSpillage

“MiniSpillage is a free professional quality drum synthesizer plugin featuring high-resolution 64-bit DSP processing.
MiniSpillage includes three exclusive drum synthesis algorithms along with distortion effects and resonant filters.”

Bass Drum – Single oscillator bass drum synth with pitch sweep, internal FM and harmonic controls.
Wood Drum – Flexible wooden drum model synthesizes natural and synthetic timbres from log drums to toms.
Hi-Hat – Six oscillators closed and open hi-hat generator with a noise source and dual resonant filters.

This is a great free option for those that want to create their own drum sounds with modulation, filtering and distortion effects.

4. Crystal Synth by Green Oak

This is one is a bit frustrating and takes a while to get anything remotely usable. The interface is on the clunky side. But a little patience can be rewarding.

5. Lokomotiv

Lokomotiv is an analog retro synthesizer that is impressive from the first launch. Its austere interface is surprisingly responsive and sounds immediately great.

Oscillator:

Mathematically generated high definition Oscillator without using wavetable or interpolation.
Silky smooth 9X detuned sawtooth wave.
Pulse wave with self PWM.
Shape morphing sub-oscillator.

Filter:

MG ladder modeling multimode filter featuring Zero Delay Feedback technology.
Routable filter Drive (Pre/Post).

Modulator:

Natural Curved ADSR Envelope generator.
One-shot LFO which can be used as envelope.

Specification:

1X OSC (Saw+ Pulse) + One Sub OSC, Noise Generator.
1X multimode Filter with Drive.
1X LFO, 1X Envelope Generator.
Eight polyphonic voices, Mono and Legato mode supported.
64 Factory presets included.
Native 64-bit, Mac and Windows OS supported.

6. Digits from Extent of the Jam

This one sports a subdued color palette with beefy growls, preset chords and brass sounds. A bit of crackling when parameters are modified, but worth the time to download for sure.

7. Spitfire Audio – LABS

Not long ago, Spitfire Audio released an ongoing series of completely free instruments called LABS. These are very, very simple sampled instruments with just a handful of controls and they sound really, really good. So far the collection includes:

Charango
Electric Piano
Amplified Electric Cello Quartet
Drums
Strings
Soft Piano

If you’ve used any of the Spitfire Sample Libraries before, you know how well they’re recorded, and these instruments are no exception. While you won’t get the flexibility or deep sampled variety of a full-scale library, you will get a great sound that can be slightly varied to taste. While these are sampled instruments as opposed to synths, they’re free and so good that I felt they warranted inclusion.

8. TAL NoiseMaker

This is one my of favorite choices. The interface is accessible, clean and to the point and thick, beefy sounds are possible from the get-go. Really nice!

From the developer: “TAL NoiseMaker is an improved version of TAL-Elek7ro and has a completely new synth engine and a lot of improvements in sound and usability. The synth also includes a small effect section with a reverb, chorus and a simple bit crusher effect. A display shows the knob and slider values. This allows more control over the synth. A ring modulator and a syncable triangle are also part of this synth.”

TAL NoiseMaker includes new filter types and the self-resonating 6 dB low pass and notch filter. Its improved amplitude ADSR is very suitable for slow pads and for really fast envelopes. 128 factory presets included, 80 made by Frank “Xenox” Neumann.

Features:

Three Oscillators. Osc 1, +/- 24 semitones, fine tune, phase control (saw, pulse, noise). Osc 2, +/- 24 semitones, fine tune, phase control (saw, rectangle, triangle, sine). Sub Osc (rectangle).
Osc 1 PM for pulse waveform.
Osc 2 FM controlled by Osc 1.
Osc 1 & Osc 2 sync to sub osc (saw, pulse, rectangle, triangle (bipolar sync)).
Adjustable master tune and transpose.
Up to six voices.
Portamento in mono and poly mode (off, auto, on).
Ringmod modulates Osc 1 with Osc 2.
Self resonating 4x oversampled filters (24 dB LP, 18 dB LP, 12 dB LP, 6 dB LP, 12 dB HP, 12 dB BP, Notch).
Filter ADSR (negative and positive).
Volume ADSR
Routable ADSR, modulates Filter, Osc 1, Osc 2, PW, FM (negative and positive)
Two LFO’s with different running modes: free, sync to host, triggered by note. Modulates filter, Osc 1, Osc 2, FM, PW, LFO rate, Panorama and Volume. Sine, Triangle, Saw Square, S&H, Noise. Positive and Negative modulation. Phase control.
Adjustable Velocity-dependent control over volume filter contour and cutoff.
Adjustable Pitch Wheel control over Cutoff and Pitch.
One pole HP filter.
Detune, detunes notes randomly.
Juno chorus with different modes.
A built-in reverb and delay.
Adjustable filter drive.
Bitcrusher affects Osc 1 and Osc 2. It’s a pre-filter stage effect.
MIDI Learn for all knobs.
Panic button.
Easy to use, no hidden panels.
256 great presets (Presets by Frank “Xenox” Neumann, The Unshushable Coktor, Alexandra Sendy, TAL, Patrick Kunz).

9. Thump by Metric Halo

Thump is a unique audio processor that allows you to synthesize low-frequency audio to add low end to a track or generate another sound entirely. Thump looks at the pitch and dynamics of its audio input and uses this information to control its oscillators. You can add low end to drums, augment a bass or even create synthetic drones.

Thump is ideal for beefing up a kick drum, adding low end to percussive tracks, recreating classic drum synth sounds and more. You can use Thump’s envelope driven, percussive sub-harmonic synth for the following things (among others):

Build low-octave support for bass drum, tom, snare and other percussive tracks.
Create kettle drum sounds from regular drum tracks.
Recreate the sounds of classic drum synths like the TR-808.

The effect of Thump is similar to generating a sine wave or other waveform on a gated track that is side-chained to a transient on another track such as a kick. But Thump allows more control, two oscillators that can be changed on the fly and more pitch specific envelope control. If you like kicks that are thick as hell and challenge the range of human hearing, you will like Thump a lot.

NOTE: the instrument requires a transient input to be activated so you would use it like an insert rather than a standalone synth.

10. Synth 1 by Daichi Laboratory

While the interface is a bit nasty and pixelated, Synth 1 by Ichiro Toda is modeled after the Nord Lead 2 Red Synth and sounds decent. It doesn’t take long to get a few usable sounds and the onboard arpeggiator is great for experimenting. (Manual)

11. PG-8X by Martin Lüder

“The PG-8X is a virtual synthesizer, inspired by the Roland JX-8P with the PG-800 programmer. The synth architecture is a standard 2-oscillator -> Filter -> VCA design. These elements can be modulated by a common LFO and one of two envelopes. The PG-8X is patch compatible with the JX-8P and can read and write JX-8P Sysex data”. (Manual)

Conclusion

While these instruments may not be the best things in life — they are free. And it has been my experience that there is something to be learned from every piece of software, as there is from all types of music. Experimentation and exploration yield untold rewards for the adventurous, and freeware is a great place to start your journey or a means to unshackle yourself, at least temporarily, from the financial constraints that plague us all.

When it comes to VST synths, you can decide on whether you want to buy one, or you want to download one for free. Naturally, the best VST synths are really the one that you’re gonna have to buy. But there are a few gems out there that are for free.

However, there are so many “free VST synths” that downloading them all and installing them on your computer and DAW can be too time consuming.

So for this article, we’ve researched and compiled ten of the best free VST synths. That’ll eliminate a lot of trial and error for you.

Interested in seeing what they are? Keep reading…

The 10 Best Free VST Synths to Use

Check out these other studio and music production gear:

# 1 – Synth1 by Ichiro Toda

If there is one free VST synth that you want to get yourself familiar with, it is the Synth1 by Ichiro Toda. This synthesizer is actually a favorite among many music producers, and is often the one that’s most recommended.

Synth1 is an analog modeled subtractive synthesizer. It’s functions are modeled on the Clavia Nord Lead 2 Red Synth.

It features 2 oscillators, which can be modulated via FM, ring, synchronized, modulation envelopes. Using the 4 types of filters, you can sculpt some cool and interesting sounds, adding distortion for effects.

It has 2 LFOs, an arpeggiator, and tempo delay. These functions are synchronized with the host digital audio workstation’s BPM.

As far as effects goes, you get the ability to add stereo chorus and flangers.

In writing notes, you have legato mode as well as portamento for interesting slides, yet the ability to play up to 16 notes polyphony.

You have a total of 128 presets, and its controls can be automated.

Synth1 was optimized for light CPU load using SSE instructions. Definitely the first choice in “freeware” soft synthesizers.

Demonstration

# 2 – FireBird 2 by Tone2

After Synth1 we have FireBird, a synthesizer that was actually premium synth you had to BUY until the developers at Tone2 decided to release it for the masses after 15 years of development.

Tone2 is responsible for some of the best VST synthesizers on the market, many of which are used to create chart topping hits, FireBird 2 is one of them. So this is definitely recommended for your collection.

FireBird 2 is a subtractive synthesizer with a very intuitive and easy to use interface to navigate its 437 preset sounds. That’s a lot of presets for a free VST synth…

FireBird 2 features Harmonic Content Morphing, which utilizes a large range of standard waveforms that can emulate the sound of many instruments, acoustic or synthetic (kind of like wavetable synthesis).

The synth comes with 38 types of filters, including your standard low-pass filters, comb-filtering, EQ, Phaser, Vocal filters, plus FM and AM modulation, to name a few. It also comes with an arpeggiator, so no need to use an external arpeggiator with this device.

You can also customize its look as it has several skins you can download or create to change the interface.

Overall, another very good synthesizer to use, which has been used commercially on chart topping hits.

# 3 – Crystal by GreenOak

If you want a synthesizer programmed by the same person that made Omnisphere, one of the titanic synths in existence today, look no further than the Crystal by GreenOak.

This synthesizer is unique also because it’s available for iPhone. There are many user reviews talking about how great this synth works as a possible free alternative to Omnisphere (there’s another alternative below as well). Of course, don’t expect the same power, nor does it come with any samples.

However, that less power means it won’t be a resource hog on your computer (something Omnisphere is known to be). And you can find free and paid for soundfonts (.sfz files) all over the internet.

In terms of features, it’s credited as utilizing both subtractive synthesis as well as FM synthesis technologies. It’s modulation controls offers 90 parameters, multi-stage envelopes, tempo sync, delays, built-in effects for chorus, flanger, filters, echoes. It has everything you’d need in a synthesizer, which is great for someone learning. You can also use automation, as MIDI controls.

Overall, another good option for a free synthesizer.

# 4 – TAL-NoiseMaker by TOGU Audio Line

Next on the list we have TAL-NoiseMaker by TOGU Audio Line. We came across this synth because it was actually recommended (along with Synth1) as one out of two best free vst synth to use by a professor on synthesis. Mainly because it consists of all the aspects of synthesis that you need to be familiar with, as a beginner, plus its ease of use.

Looking at this synth, you can see why. Everything is laid of clearly, you don’t have to searching around too much for controls that you need when designing a sound.

This actual version was designed as an improved version of TAL-Elek7ro, which comes with an entirely new synth engine, with a few effects like reverb, chorus, low pass filter, and a bit crusher. You also get ring modulation as a synch-able triangle.

The ADSR is very suitable for slow pads or fast envelops attacks. It comes with 128 factory presents, 80 of which were designed by Frank “Xenox” Neumann.

It total, you receive 3 Oscillators, which can each be programmed individually for phase modulation, frequency modulation, or to generate sawtooth, pulse, noise, triangle, sine, square, or rectangle waves.

You get up to 6 voices, which is not a lot but not bad, which can be played in legato, portamento, or polyphonic.

All knobs can be learned via MIDI and automated within your DAW.

Overall, considered an incredible synth, chock full of features, and won’t disappoint as freeware plugin device.

Demonstration

# 5 – Dexed by Digital Suburban

Dexed by Digital Suburban This is a dedicated FM synthesizer, which is excellent for those looking for a frequency modulation synthesizer either to learn, or to general specific sounds. It’s actually designed based on the Yamaha DX7.

This soft synth was created for the intention of being a tool or companion to the original Yamaha synthesizer, particularly for those studying FM synthesis. However, it can be the go-to free synthesizer for those wanting to make some vintage sound genres like Synthwave, which were created using the vintages synths of the day like Yamaha DX7.

Many have considered it an improvement on the actual Yamaha model, plus it being lightweight, it won’t be resource hog on your CPU.

Expect it to work with your digital audio workstation, and to find lots of patches and presets on the web for you to download and to use.

Demonstration

# 6 – MiniMogueVA by Voltkitchen

If you’re looking for a free alternative to Arturia’s Minimoog, or G-Media Minimonsta, then this MiniMogueVA is your choice!

The MiniMogueVA has so many good reviews that it had be on the list. As the name suggests, it’s modeled to match the original Minimoog synthesizers designed by the legendary Bob Moog. Expect the sounds it produces to be particularly rich and juicy, great for funk style music, electronic bass music, and the sub bass in dubstep wobbles.

It features 3 oscillators, one with tuning control, the other two with fine-tuning sliders, and the ability to turn the third oscillator into LFO with dedicated modulation knobs.

Though the original Minimoog had no noise generators, this one actually comes with a the ability to create pink and white noises from the third oscillator.

As to be expected, you get chorus, and delay effects among others, as well as the ability to use MIDI learn to control your software device.

Many people overwhelmingly consider this the absolute best free VST synth on the freeware market. The Minimoog sounds featured in Omnisphere are great, so it’d be awesome to give this a whirl.

Demonstration

# 7 – Proteus VX by E-MU Systems

E-MU systems is the maker of pro audio gear, from hardware synthesizers, audio interfaces, wireless audio transmitters, and digital-analog converters, software instruments, and even audio cables. They’re well known for their quality products, but they also have hidden gem in the “freeware” market: Proteus VX, a free VST synth.

Actually, it is rompler, meaning that it also utilizes samples as well synthesized sounds (like Omnisphere, hence, a worthy free alternative). It was base on the Proteus 2500, a vintage hardware synthesizer. It has the same sounds and factory bank as the original version, plus the ability to control it via 16 MIDI CC controls.

It features “High Voice Polyphony,” which is dependent upon the power of your system, and 54 different filter types, including multi-pole resonant filters, phasers, flangers, vocal filters and multi-parameter morphing filters.

Another cool thing about it is that it offer 24-bit 192kHz high quality audio playback. So you can expect an actual pro level audio quality from a synth that’s actually for free!

Being drag-and-drop based, you have select your presets easily, plus it can be used VSTi within your DAW, or as a stand-alone application.

Only downside… it isn’t supported anymore. Meaning that there aren’t anymore updates. But you can grab it and see it works on your system.

Demonstration

# 8 – Superwave P8 by Superwave

The Superwave P8 is a virtual analog subtractive synthesizer that’s considered the go-to emulator of the vintage synth Roland JP8000. This one perhaps one of the few if not only best free VST synth on this list that is more suitable for an advanced user than someone who is just starting out. It features many controls and parameters that can be overwhelming to a beginner, but satisfying to a pro.

Now, about its sound, which should be the primary reason to using a synthesizer. Considering that it’s loosely modeled off the Roland JP8000, its users have considered it one of the best sounding free VST synths on the freeware market. Expect it to have a fairly unique sound suitable for trance, new age, electronic music, house, or even pop. The pads are what many users consider its most attractive asset, because of the richness and thickness of the sounds that the P8 produces.

It features 2 oscillates that will producer sine, sawtooth, ramp, triangle, pulse waveforms, as well as white noise and pink noise. You can control the oscillators with using fine-tuning, detuning, and synchronized modulation. Its filters consist of 2 resonant filters, low pass, band pass, and high pass. It has 2 controlled amplifiers by level, pan, and on/off switch. The effects I see is simply a pair of mono delays, which can be controlled. You get up to 8 notes of polyphonic operation, portamento controls, and 64 high quality presents, all which can be controlled using MIDI CC control with “learn” capability.

If you aren’t familiar with it, and you already know your way around synthesizers, give it a try yourself. Chances are, from other reviews I’ve read, it is worth looking into.

Demonstration

# 9 – OB-Xd by discoDSP (prev. Datsounds)

Best Free Synth Plugins For Fl Studio Studio 20

There is a challenge with curating this list of best free VST synths, because, so far, many of the VST synths we have named can really be considered the “best” free synthesizers you can download. And discoDSP’s OB-Xd is constantly referred to as the “best” as well. And listening to its sounds, utilizing it’s interface, and working with its features, it’s hard to not see why this synth isn’t actually THE best. But, so are many of the others on the list…

So, what makes this one unique?

For starters, it was modeled on the Oberheim OB-X, OB-Xa and OB-8 synthesizers. These classic vintage hardware synths were famous back in the day, and contributed to many hit records. Right now, they continue to enjoy their legacy in this freeware plugin.

The developers claim that they are not “copying” the originals, but rather take the same features and improve upon them. Whatever that means, it just sounds good to me.

Expect all the features you should find in a standard synthesizers, as well as some cool sounding features like the “continuous blendable multimode filter,” which is a filter allowing you to blending different filter types (such as high-pass, band-pass) in different dB modes. Also, it works on 32 bit or 64 bit versions of Windows OS, as well as Mac.

If you want the classic sounding vintage synth Oberheim for practically nothing, or at least to get yourself familiar with it, give it a trying and download it.

Demonstration

# 10 – 44 S by GTG

Free Synthesizer Fl Studio

Finally we have a synthesizer crafted by someone who creates synths strictly for personal use. Yes, the 44 S by GTG is synthesizer created by a musician and synthesist, and offered to the public for free.

Actually, there are many synthesizers by this creator for free, so you can take a look at his entire collection, starting with this GTG 4 S.

This particular synth was design to give a flat sound that you can sculpt. You can use the filters for creating interesting and pleasing distortions in the resonance. It also feature filter modulation, pulse-width modulation, and the ability to track the LFO with the keyboard.

Free Vst Plug-ins For Fl Studio

This definitely another synthesizer to consider to try using. It is free, and has a good sound. Check it out.
