Top 20 FREE Synth Plugins For Musicians 2023 (All Sorts of Synths)

1. ujam Usynth Drive

More Info & Download

Usynth Drive is a free synthesizer, sequencer, and effect plugin by ujam.

It’s a simple-looking plugin with an intuitive interface but has excellent functionalities under the hood. The synthesizer section packs wavetable, virtual analog, FM, multi-sample synth engines, modulators like multi-mode filters, a 5-stage envelope, LFOs, a modulation matrix, and more.

Drive is great for creating House music but has good sound design options for pop, RnB, funk, retro, and many dance genres.

Key Features:

  • Easy to use
    The plugin is designed to be used by anyone, whether a beginner or a professional. It has about a hundred presets split into categories like Keys, Leads, Plucks, Pads, and Effects. However, the plugin is not as easy as it looks, but the complexity doesn’t appear in the workflow, as it stays in the synth design only.
  • Simple synthesis workflow
    Usynth Drive has a synthesizer section, which two knobs can control: Dark/Bright and Fast/Slow knob. Further, there are knobs like Calm Down, Scream, and More Sub. You can change the presets for the synth window by using arrows and a dice, by which you can select anything from bass sounds to pad sounds.
  • Sequencer Engine
    The switchable sequencer allows you to adjust the rate between quarter and 1/32nd note. You can also sync it to the BPM and key and select various patterns. Further, you can adjust the note length, swing, octave shifts, and pattern length.
  • Finisher section
    Finisher is a multi-effects section that consists of 60 different effect combinations that you can set at every instance of the knob. Every Finisher preset is a different configuration of different effect modules.
  • Generative functions
    All sections consist of the Surprise button, symbolized by the Dice icon. You get fresh Sequencer and Finisher ideas and presets when you click on them.
  • Under-the-hood functionality
    The knobs/controllers that appear very simple from the outside have complex functionalities hiding behind them. For example, the bright/dark knob helps you adjust the harmonic content to get even harmonics at the bright end and odd harmonics at the dark end.
  • Detailed editing
    Drive lets you go in-depth with your sound design by adjusting the mix of effects like a multi-band compressor, transient, chorus, and focus EQ in Finisher. You can set the intensity of the Surprise switch to range from small to big. In addition, you can adjust the delays, spreads (stereo imaging), reverb (ambiance/stadium), etc.

Compatibility:

Drive is available in AU, AAX, and VST 2 plugin formats and requires a minimum of macOS Catalina (10.15) or Windows 10 operating systems, 8 GB of RAM, and 1.23 GB of hard disk space.

Summary:

Ujam has created a great synthesizer with high-quality sounds, presets, and effects. The plugin is easy to start with and has a simple workflow with a user-friendly GUI. The bass sounds are fat, punchy, warm, and sounds analog. The pad sounds are lush, spacious, and wide.

2. Matt Tytel Vital

More Info & Download (Paid Version Available)

Vital’s synthesizer brings spectral oscillator warping to add new life to your wavetables.

Acting directly on a waveform’s harmonics, this technology can create drastically different tones and shapes from a signal source. Thanks to this simple tool that creates endless possibilities, what was already incredibly customizable became even more so.

If you want to import your samples to create a wavetable, Vital’s pitch-splice and vocode converter are two great and easy add-ons to get even more specific on your sound design.

You can also develop wavetables from scratch via the built-in wavetable generator or even directly from the text!

Key Features:

    • Excellent oscillators
      These oscillators have a shallow low noise floor and a sharp cut-off at Nyquist for almost no aliasing, creating the cleanest sounds with the best quality possible. “Nyquist” means that each periodic signal should be periodically sampled at a rate twice the size of your audio signal. So, to overcome this, a higher quality sampling is sought after on synths like Vital – and a cut-off might be the simplest tool you’d ever need.
    • Microtonality at its best
      This synth can load .tun, .scl, and .kbd files –  which can alter and configure how the tuning will perform – and play in a microtonal setting without any trouble. A brand new tuning system can unlock new possibilities regarding how the samples perform. This expands how you’ll play notes and frequencies and how to sample and interact with one another via the oscillators.
    • Key-tracked LFOs
      It’s possible to create key-tracked bass lines with this LFO setting, combining it with an audio-rate modulation and using your LFO as an oscillator modulation source. This enables you to instantly automate certain modulation parameters in relation to whatever notes are being played.
    • MPE support
      If you have a ROLI keyboard, a Linnstrument, or other MPE-compatible gear, Vital offers full support and control. This way, you can add more expression to your sound and use dynamics as you’re used to.
    • Audio-rate modulation
      The audio modulator kicks in when you have an audio signal or a parameter being varied and brings much more personality to your tones.  The variations can be tracked down and edited in the most creative ways possible. The signal whose waveform is used to trigger is modulated accordingly, with extreme precision and character.

Compatibility:

The plugin is available for mac OS 10.12 or higher, Windows 10 or higher, and Ubuntu Linux 18.04 or higher. All 64-bit only, with OpenGL 3 or higher. It comes in VST, AU, and LV2 plugin formats.

Summary:

Vital Audio brings a different wavetable synth than most, especially regarding creating new sounds. Most allow you to develop wavetables based on audio files, but this is probably the only one on this list that can handle microtonality, text input, and effects like vocoder and pitch-splice.

The warping oscillator ensures that each harmonic will be shaped to your desire, and this is truly unique to find in a synthesizer.

3. Newfangled Audio Pendulate (Great For Bass & Subbass)

More Info & Download

Newfangled Audio Pendulate Review - 5 Best FREE Synth Plugins | Integraudio.com

Pendulate, by Newfangled Audio, is an impulsive free synth that borrows the double pendulum engine from its paid sibling.

The plugin offers an innovative synthesis method based on a double pendulum, a chaotic system governed by ordinary differential equations. In short, the plugin generates sound from a sine wave, and you can shape it with the six oscillator parameters. In addition, the Wavefolder section helps you add wave-bending harmonics to the sound, and the Low Pass Gate offers an ADSR and a smooth sound.

Key Features:

  • Global
    Here, you can set the parameters for voice and pitch on a global scale. In addition, the modulation sources within this area let you add MIDI and MPE modulation into any parameter in Pendulate’s upper half.
  • ADSR
    This section creates three modulations sources when a note is pressed
    . You get a full-envelope ADSR modulator, an ADR envelope, and an ASR. These slightly different shapes let you affect multiple parameters with similar intentions but exceptional results.
  • LFO
    Lastly, we have a single LFO with five outputs in the modulation chain
    . Each modulation output offers a different waveform that you can use to modulate other parameters. For example, the LFO gives you sine, triangle, pulse, sawtooth, and ramp waveforms.

Sound & Usability:

While the upper half has been mostly copied from Generate, the lower half of the plugin offers limited effects and modulations. And even though that was expected, it isn’t bad for Pendulate’s users. Having more LFOs and envelopes would be nice, but this is a free plugin.

As a sample for the paid version, this plugin works marvelously, as it also borrows the user-friendly experience from Generate.

It’s absurdly easy to create modulations. You can click the circles and drag and drop the mouse into the [+] of whatever parameter you want to modulate from the bottom half.

New Pendulate Chaotic Synth Plug-in by Newfangled Audio (Presets Demo)

Compatibility:

This plugin is available for Windows 8.1 and higher and macOS 10.9 and newer in AAX, VST, and AU formats.

Summary:

Newfangled Audio’s Pendulate is a powerful plugin in its own right, but it’s merely a slice out of Generate’s pie. Nevertheless, it’s a worthy addition to your collection thanks to its one-of-a-kind synthesis method. So if you’re looking for a specific sound to add to your productions, try this one out, and you won’t regret it.

More Info & Download

Surge Synth Team Surge XT - Top 12 Subtractive Synth Plugins (And 8 FREE Synths) | integraudio.com

The Surge XT is one of the best and most advanced open-source subtractive synthesizers.

It has a unique interface and signal flow. It operates under two scenes, with three oscillators in each scene, resulting in a total of 6 oscillators, with 64 voices of polyphony. In addition, it’s a modulation-heavy plugin with eight macros, six LFOs, two envelope generators, and other modulators. 

Key Features:

  • Easily Adjustable signal flow
    Under the Filter Configuration windows, you can set how and in order the filters are applied to the sound. There are eight different types of configurations that you can set, with three serial, two dual, a stereo, a ring, and wide types. You can also map it to the controller or key and add automation lanes. By default, it’s set to Wide, as it’s stereo and will allow you to get the best results out of unison voices.
  • Scene Modes for layering and splitting the sounds
    The Scene modes decide how the scenes can be used together, whether layered or split. Single mode allows you to play only the selected scene simultaneously, whereas Key Split allows you to play different scenes on different keyboard parts. The third mode, Channel Split, will split the scenes to be played by the midi channel. Lastly, the dual mode will allow you to play both scenes together.
  • Wide Oscillator Section
    Three oscillators per scene can be mixed, soloed, muted, and even multiplied or cross-fed into each other. In addition, the oscillators can be key tracked or retriggered, and we can change their pitch up to three octaves above and blow. Further, their pitch, shape, pitch range, width, sync, unison detune, and unison voices can be changed and edited.
    Further, you can choose the oscillator type from an insane number of options, including classic (saw and square), modern (triangle, sine, saw, and square), wavetable, window, FM, String, twist, Noise, and more.
  • Huge scope of modulations
    The modulation matrix is located right at the bottom of the GUI. Here, we can use the MACROS to control multiple parameters simultaneously with a simple drag-and-drop option. Almost every knob and slider in the interface can be modulated using the macros, and you can also rename the modulators as per your taste. However, the modulators in the plugin have so much depth and options that it could take a while to explore the software completely.

16. Hvoya Audio Ribs (Granular Synth/FX)

More Info & Download

Hvoya Audio Ribs - Best DJ Audio Plugins (And Live Performance) | integraudio.com

Ribs is a granular synthesizer and effect unit designed by Hvoya Audio. 

Ribs is an unusual and intriguing synth/FX unit. At its core, it’s a granular device that captures sound, chops it into granules of audio, and plays them back in beautiful ways.

It can also perform cool scratches that can be realistic or totally creative and unique, break audio down and turn it into new soundscapes, or even create interesting transition effects. What’s even better is that it’s free to use.

Key Features:

  • Three performance modes
    Ribs have three performance modes, simple, notes, and beat. There is no granular processing in simple mode, and Ribs play back the buffer content. In notes mode, the audio is cut into pieces and put back together to create new notes. Finally, the beat mode works like the notes mode. The only difference is that the audio pieces’ length depends on the tempo of your DAW and other customizable parameters.
  • Scratches
    Scratching is just the surface of what Ribs can do, but it can perform them in amazing ways. All you need to do is record the audio you wish to scratch in the internal buffer and then move your mouse over the waveform. The mouse will move a virtual playhead which will create scratches. What’s awesome about Ribs is that you can assign said playhead to a midi control on your midi keyboard, for example, a knob. Now, you can just play your song and move the knob to perform scratches. Remember to always capture the audio in a separate channel because Ribs cannot save buffer contents. Scratch is available in simple mode.
  • Excellent for sound design
    Like any granular software, Ribs is an amazing sound design tool. It can birth to complex polyrhythmic beats and create rich and evolving atmospheres. Its ability to chop audio into granules and reproduce it in different orders and ways means that anything you feed into it will give you vastly different sonic results. If you’re into experimental music, sound design, or just fun, this plugin will be extremely joyful.
  • Excellent for live performances
    The ability to assign different parameters to midi controls is just one of the reasons Ribs is excellent to use in a live setting. For example, you can record a vocal performance live and send it to Ribs to modulate. If you own any midi controllers, then you can assign different controls to different knobs and buttons in advance to have an interactive and fun live performance.

Compatibility:

Ribs is available on Windows and macOS in VST, AU, and Standalone formats.

Summary:

Ribs are a fun tool if you’re into sound design or live performance. You can get it for free, so I recommend it to anyone looking for a new granular device to play with. The scratching sounds realistic and quirky, while the different performance modes enable a wide range of sound design possibilities.

Zebralette, by u-he, is a free, miniaturized version of a paid synth, the Zebra2, that keeps some of its goodies.

The plugin offers an oscillator, one envelope, 16 voices of polyphony, 2 LFOs, and three built-in effects. Additionally, you can use MIDI interfaces to control most of the plugin’s parameters. Zebralette was developed to work as a learning interface for the Zebra2, but it turned out to be a great synth on its own, thanks to its robust oscillator.

Key Features:

  • Oscillator
    The heart of Zebralette’s sound is the thorough Zebra2 Oscillator
    , which gives you all the expected controls, including 1, 2, 4, and 11 unison voices. The wavetables are shaped in the Wave Editor, and you can save your modifications by clicking the Presets button.
  • Wave Editor
    The big graph-like panel in the middle of the oscillator area allows you to create and edit up to sixteen wavetables in four different modes
    . There are two Morph Modes and two Blend Modes, each with distinctive build characteristics that add versatility to your oscillator. You can use the Wave knob to change and blend the wavetables.
  • Morph Modes
    These are handle-oriented shapers. In GeoMorph mode, you can add up to 32 handles to adjust the curvature to taste. In SpectroMorph, you’re not handling the waveforms but the harmonic spectrum. There are 1023 harmonics spread logarithmically across 10 octaves, and when all handles are at the same level, you get a sawtooth wave.
  • Blend Modes
    GeoBlend, the first mode, 
    depicts the waveform, but each cycle is represented by 128 vertical bars. Thus, when you turn the Wave button, the waves are cross-faded. The next mode is SpectroBlend, in which the harmonic spectrum is depicted by 128 bipolar bars, which show the in-phase and anti-phase harmonics.

Sound & Usability:

Zebralette’s sound is shockingly interesting for a single oscillator synthand with 300 presets, it’s also easy to get started with. The simplified interface makes for an easy-to-learn plugin, and the phaser and delay effects further its versatility. Moreover, adding the MSEG to this free plugin is astounding, making it possible to achieve crazier-than-normal sounds with this simple tool.

Compatibility:

This plugin is available for macOS 10.9 and newerLinux, and Windows 7 or higher in VST, AAX, and AU formats.

Summary:

U-he’s Zebralette is not precisely a flexible plugin, but it offers enough control for you to bend it to your will and come up with unusual sounds of your own. Overall, it’s a beginner-friendly plugin that deserves a place in your toolbox.
