Best Free Synth VSTs
LANDR Samples now has an accompanying plugin that makes it easy to audition, time stretch and pitch shift any sample on our marketplace.
If you’re interested in getting into the stranger realms of FM synthesis, here’s an interesting synth from open-source synth maker OctaSine.
It comes with four operators with a flexible routing feature that makes it easy to build your own synth path.
OctaSine also features four assignable LFOs and an ADSR section for each operator.
If OctaSine isn’t weird and crazy enough for you, Pendulate should do the trick.
Its waveforms are literally called “Chaos Shapes”. The routable synth can send audio signals through a wave folder, a pitch mod section, ADSR and LFO.
It comes with a clearly laid out mod matrix to bend your oscillator signal into any chaotic sound you desire.
Here’s a super warm and cozy sample-based synth that re-creates the nostalgic and vibey sound of the Fender Rhodes.
Sample Science did a great job of recording the instrument onto cassette to create this lo-fi inspiration machine.
Definitely try this one out if you’re looking to add Rhodes keys to your track.
Light Pad is the lightweight edition of UhhYou’s Cubic Pad. Both are powered by Paul Nasca’s interesting PADSynth algorithm.
The best part is that you get to manipulate the waveshapes directly using a visual editor
If you’re tired of endless emulations of old analog hardware, Light Pad could be the futuristic computer synth of your dreams.

The Nordic-themed Odin2 synthesizer from TheWaveWarden is a new contender for the most advanced free synth plugin.
With an editable wavetable oscillator, loopable envelopes, multiple filter models and extensive modulation matrix, Odin2 pushes the boundaries of freeware while sounding great!
Best Free Drum VSTs
Here’s a drum VST that focuses exclusively on one instrument—the snare drum.
It’s capable of creating convincingly realistic snare sounds with a handful of parameters for very specific variables like stick tip hardness, snare tension and hit position.
If you’re struggling to get real sounding acoustic snares using digital plugins, give this one a try.
Best Free Guitar VSTs
Kabin is a guitar cabinet modeler that makes it possible to create the sound of any guitar cab in your DAW.
The plugin comes with options for setting speaker and cabinet size up to 1×12”, settings for character to adjust mid-response and dynamic response, and a tube mic placement option.
If you’re looking for a great way to model your dream amp and get better direct-in guitar tone give Kabin a try.
Best Free Compressor VSTs
SPECOMP is an S-Type console compressor from Analog Obsession. If you’re looking to re-create the sound and magic of classic spectral analog compressors in your mix definitely give this one a try.
The compressor has fairly simple settings but it’s a great tool for gluing everything together with a genuine re-creation of the original’s circuitry
BusterSE is an excellent (and free) recreation of the classic SSL bus compressor on the G-series console.
BusterSE is a stereo compressor, meaning it can work on multiple sources at once. That’s why it works so well on the master bus and is known for gluing a mix together in the final stages.
Here’s a very unique way of thinking about compression from Semantic Audio. SAFE compressor works by reading descriptive keyword entries by a user and adjusts compressor settings accordingly.
For example, you could type in a command like “bright” or warm” and the compressor will adjust its settings to fit those semantic descriptions.
Best Free EQ VSTs
Analog Obssession’s FIVER EQ is an excellent recreation of the classic SSL G-series console EQ.
This is definitely a go-to workhorse EQ you can reach for anytime you reach the EQ stage of a mix.

Here’s another great three-band, mono and stereo, mid-side processing EQ plugin from Analog Obsession.
MASBAX comes with 6 frequency selections for low, mid and high EQing duties and adjacent high, mid and low boost and cut amounts to help you carve out the best sound.
NCAR is a really cool way to introduce classic analog workflows into your mixing practice.
The summing analog mixer makes it possible to route different inputs through a master mix channel to add EQ cuts and boosts and level each input track in one area.
It sounds great and also looks great with its classic mixer-style interface.
Best Free Reverb and Delay VSTs
Spread delay gives you a high degree of control over the panning of your delay bursts. It comes with a visual interface that lets you control exactly how wide your delay will ping-pong.
For some interesting sound design applications this delay is a great free addition to your delay plugins.
Dragonfly is a collection of plate, hall and room reverb plugins—each coming with their own unique set of parameters and controls.
It’s a bit unique because the plugin interface comes with a spectral analyzer that helps with analyzing which frequencies are getting reflected most prominently.
Tape echo is one of the most beautiful delay effects out there. Vintage hardware like the Space Echo or the WEM IC-400 is still beloved for its nostalgic, saturated, lo-fi sound.
The GSi Varispeed is a convincing re-creation of the WEM IC-400, it opens up many echoey sonic possibilities for adding a tinge of tape-infused lo-fi goodness to your tracks all for free.
OrilRiver is a pretty comprehensive algorithmic stereo rhythmic reverb that comes with a lot of functionality—it’s fairly competitive with higher tier paid plugins.

Best used from drums to create extra punch and crunch, but definitely don’t shy away if you want to mangle and distort any audio source.
Here’s a well engineered plugin from Germany based TBProAudio. It’s based on the saturator used within their paid CS5501V2 channel strip plugin, but with some extra design features added.
It comes with several different saturation modes, oversampling and a pretty cool old school VU interface.
Best Free Vocal VSTs
Best Free Filter VSTs

It’s a refreshing alternative to painstakingly writing automating your synth parameters by hand.
Dirty Filter is a fairly standard filter with HPF and LPF options and a mix knob for blending filtered sound with the original signal.
What makes it unique is its included overdrive parameter that adds extra saturation and resonances that sound great when brought into focus by the filters.
If you enjoy using sloping filters to sculpt squelching, chunky sounds this is a great free plugin to experiment with.
Here’s a powerful filter with a ton of capabilities, especially for a free plugin.
You get a lot of ability to customize each of its three bands, modulation parameters to add LFO, overdrive, attack and release and even an EQ section.
This is about as close to a fully fledged filter plugin as you can get without spending a dime.
This is a beloved cheese themed plugin that you need to put in your plugins folder, even if just for its quirky design and sound.
The multiband, resonant filter comes with parameters for adding distortion and two routing schemes and delay stages to create unique phasing effects.
This plugin has a ton of sound design applications and easily qualifies as one of the weirder plugins on this list.
