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.

3 FREE Max for Live Devices
Download three free Max for Live Devices from Phil Mantione.
FL Studio is one of the most powerful music production tools around, with an array of synths and effects available right out of the box. But like most producers, you could probably use a few more plugins! Here we’ve put together some of the best free plugins for FL Studio, which should cover you for almost every imaginable musical scenario.
Sitala
Download for Free
Sitala is a drum plugin that can also be used as a standalone app. Although it is about as simple a drum plugin as you could want, it will find a place in almost any project due to its musicality and highly intuitive interface. Sitala’s six knobs and sixteen pads encourage you to use it as an instrument, which results in more musical beats and grooves.
Best Features & Specs
Sitala features 16 assignable pads that should be familiar to anyone who’s ever used a drum plugin before. You can drag and drop your own samples right into these pads or use the factory kits that come with the plugin.
Sitala also includes an array of sound-shaping tools that lets you put your own stamp on your drum sounds. With features such as ‘Shape’, ‘Compression’, and ‘Tone’, recreating traditional drum beats or more experimental grooves is a piece of cake.
Bottom-line
Like the best free FL Studio plugins, the beauty of Sitala lies in its simplicity. We found that it lets you lay down grooves quickly, and the results are always musical. We especially like how the interface allows you to play it like an instrument.
Best Free Synth Plugins Fl Studio
Piano One by Sound Magic
Download for Free
Sound Magic’s Piano One is reminiscent of the Yamaha C7 concert grand, which is highly revered by many professional piano players. Based on Sound Magic’s Hybrid Modeling Engine, Piano One combines the best qualities of physical modeling and sampling. The result is an amazingly rich and responsive sound that often felt like playing a real piano.
Best Features & Specs
Sound Magic’s Hybrid Modeling Engine does a great job of combining the realism of piano samples and the responsiveness of physical modeling. Unlike other modeled instruments, Piano One responds instantaneously, with no sluggishness or delay. The sound is reasonably rich and full-bodied, particularly when playing sustained low notes. The plugin even comes with an onboard reverb that simulates environment and soundboard resonance for added realism.
Bottom-line
Even with its limitations, Piano One is a pretty impressive piano plugin. If you need a range of basic piano sounds but don’t have the cash for a humongous piano library, Piano One is worth looking into.
TyrellN6 & Zebralette by u-He
TyrellN6 is based on the legendary Roland Juno 60, which is one of the most iconic analog synthesizers ever made. Users of the venerable classic will appreciate the simplicity and ease of use of this plugin, which lets you create deep bass, lush pads, and cutting leads with relatively little effort.
Zebralette isn’t based on any particular instrument. Rather, it is a teaser of sorts for u-He’s well-respected Zebra 2. It has the same great-sounding oscillator that is in Zebra, giving you a taste of what you could achieve with the more fully-featured product.
Best Features & Specs
TyrellN6 and Zebralette give you a pretty diverse range of sounds, from classic to cutting edge. TyrellN6’s classic architecture is the ticket to thick and lush vintage sounds, with noise and a ring modulator joining the two oscillators for extra flavor.
Zebralette is a more esoteric plugin that allows for the creation of more outlandish and experimental sounds. This is a great entry point into the sonic possibilities offered by Zebra 2, and we were thrilled to find that Zebralette patches can be opened in Zebra 2.
Bottom-line
TyrellN6 and Zebralette are compact yet powerful synths that will find a place in any modern production. Even if you already have some powerhouse synths in your collection, these two free VSTs for FL Studio are worthy additions.
Guitar M Lite II
Download for Free
Guitar M Lite II offers studio musicians the crisp and authoritative sounds of the Martin D-41 acoustic guitar in a convenient software plugin. Developed by Ample Guitar, M Lite is a great way to add glistening acoustic textures to your productions, even if you don’t happen to have a guitar player handy.
Best Features & Specs
M Lite is a sample-based instrument that weighs in at just under 850 MB. It includes standard guitar articulations such as hammer-ons and pull-offs, palm mutes, and pops, allowing you to create surprisingly realistic performances. The plugin also offers Customized Parameters Control (CPC), which lets you add more expressive touches via MIDI CC or automation.
We especially like the plugin’s Strummer function, which allows for some pretty convincing strummed performances. Strumming is where most acoustic guitar plugins fall short as far as we’re concerned, so were pleasantly surprised to find it implemented so convincingly in a free plugin.
Bottom-line
Those with discerning ears aren’t likely to be fooled by M Lite. But if you need some rudimentary acoustic guitar parts for a mockup, this plugin will do very well in a pinch.
LABS by Spitfire Audio
Download for Free
Spitfire Audio’s LABS has created quite a stir in the software plugins world, so we were eager to put it through its paces. At present, the collection already covers a pretty broad range of instruments, and more are being added all the time. And because each instrument is a labor of love by dedicated musicians and sampling experts, the results are consistently impressive.
Best Features & Specs
Each LABS instrument comes in the form of a dedicated plugin, rather than a library you load in a software sampler. We found the user interface to be focused and refreshingly straightforward, with easy to use controls for dynamics and expression. We also like the inclusion of a knob that can be customized for whatever function the user wants.
The LABS collection currently includes strings, guitars, pianos, brass, drums, vocals, percussion, synths, and experimental instruments. Although not quite as detailed as more extensive sampled libraries, we had no trouble making them fit into our productions.
Bottom-line
The LABS instruments are about as straightforward as plugin instruments can be. Even if you already have a collection of software instruments, you will probably find a use for some of these plugins.
Vinyl by iZotope
Download for Free
iZotope has long been known for its excellent noise reduction and sound improvement plugins. So it was a bit of a surprise when the company rolled out a plugin that adds grit and dirt to audio. With Vinyl, you can dirty up your tracks with a healthy helping of dust, scratches, and mechanical noise, instantly giving them the character of a vintage recording.
Best Features & Specs
As the name implies, Vinyl makes tracks sound like they are being played from a turntable. Ideally suited for every stage of the production process, we found this to be the most convenient solution to get the authentic vibe heard on ’60s and ’70s recordings.
We like how you can control how much ‘pixie dust’ you can add to your tracks. Whether you need just a few cracks and pops, a touch of mechanical noise, or you really want to thrash your audio, Vinyl provides independent control over each element.
Bottom-line
Vinyl works on pretty much everything from drums and strings to full mixes. If your tracks are sounding just a bit too clean, this plugin will let you dirty them up in a few clicks.
Ozone Imager 2 by iZotope
Download for Free
iZotope’s Ozone Imager 2 offers a quick and easy way to alter the stereo image of your tracks. Whether you need to widen a pad or string section or narrow down your bass and kick drums to fit into a mix, Ozone Imager lets you do so quickly and easily.
Best Features & Specs
The most obvious application of Ozone Imager is to widen an audio track. If you need your synth pad or string section to fill up the soundstage, Ozone Imager will get the job done without imparting any sonic anomalies that could make mixing a nightmare.
Ozone Imager provides two flavors of Stereoize: one lets you widen source audio with a cool phasing effect, while the other widens signals more subtly. The plugin also has three vectorscope meters that give you instant visual feedback on your stereo spread.
Bottom-line
Ozone Imager is a fairly simple plugin that is useful for mixing as well as creative experimentation. If you are struggling to make certain elements fit into a mix, this is one you can try out, of check out or list of other mixing plugins.
MAutoPitch
Download for Free
MAutoPitch is a pitch correction plugin developed specifically for vocals and monophonic instruments. Simple and straightforward, it is nevertheless capable of producing great-sounding results that compare favorably to more expensive pitch correction plugins. It even has formant shift and stereo-expansion features that expand its capabilities as a creative audio production tool.
Best Features & Specs
Compared to many FL Studio plugins for free, MAutoPitch has quite an impressive user interface. It can be resized freely and has standard meters as well as time graphs. It also has sophisticated multi-parameter features such as mid-side and 8-channel surround processing. We particularly like the onboard safety limiter and the automatic gain compensation (AGC) features that keep levels in check.
All MAutoPitch parameters can be mapped for MIDI control and automation. This enhances the plugin’s value as a creative tool, making it more than just a “set-and-forget” processor.
Bottom-line
From subtle pitch correction to creative sound design, MAutoPitch does it all. If you do a lot of vocal work, this plugin is an essential addition to your toolbox.
Supermassive by Valhalla DSP
Download for Free
Free Trap Vst Plugins Fl Studio
Supermassive is only one of a handful of time-based plugins that form the bedrock of Valhalla DSP’s stellar reputation. The company’s delays and reverbs compare favorably to much more expensive plugins, and their features and capabilities are well known to producers across the globe. With Supermassive, the company once again proves its expertise in developing lush and exquisite sounding plugins, with a few more tricks up its sleeve.
Best Features & Specs
Best Free Synth Plugins For Fl Studio
Supermassive is designed specifically to produce spacious and expansive delays and reverbs. Ideally suited for adding atmosphere to dry and lackluster productions, it sounds just as good when dialed down for more subtle ambiance.
Like all Valhalla DSP plugins, Supermassive is freely resizable, with precise controls for every parameter. It is based on a system of feedback delay networks, with each delay ultimately being processed by a unique WARP control. This allows you to produce everything from twinkling echoes to rich and deep reverbs and everything in between.
Bottom-line
Supermassive is easily a great VST for lush ambiance, even able to compete with our list of top VSTs on the market. Even if you already have a couple of favorite reverbs and delays, you will likely find yourself patching in Supermassive every time you need a unique atmosphere in your productions.
Pancake 2 by Cableguys
Download for Free
Cableguys’ Pancake 2 handles a variety of panning and imaging functions in a slick and easy to use interface. Like all Cableguys plugins, Pancake 2 offers full control over the most useful parameters, giving you total control over your sound. You also have plenty of options to modulate the source audio as you wish, so you have free rein over your creative vision.
Best Features & Specs
PanCake allows you to set and forget the modulation depth and rate if you wish, although you could also draw in your own modulation curves. This feature is perfect for panning audio in time with the tempo or ramping up the speed for a buildup.
Of course, the plugin’s LFO can be set to sync to your host DAW’s tempo as well. Speeds from ¹⁄₁₂₈ notes to 32 bars are possible, giving you a wide range of movement options. The plugin also has a left/right display so you always know what is going on with your soundstage.
Bottom-line
