Top 12 Free Synths Every Producer Should Know

With the endless new software and hardware synths out it’s hard to keep some money in our pocket. So we figured we’ll make a list of all the free synths every producer should check out.

You can make entire albums with great-sounding synths just with this list alone.

There are many more free synths out there that are exclusive to windows or Mac machines but we only included the multi-platform (Windows, Mac and some supporting Linux for all you nerds out there) beasts so everyone can download today and start making some awesome sounds for free!

If you find yourself using these synths a lot please consider donating to the developer who put hours on top of hours of writing code, designing and developing.

Surge is an open-source synth developed by Kurasu (Claes Johanson) and maintained by a group of volunteers.

This is a hybrid subtractive synthesizer with wavetable, FM, MPE, custom scales and over 1000 prests and over 200 wavetables.

It’s worth checking it out just for the sheer amount of prests. Super Expressive and extremely powerful it’s hard to believe this free. If you have some sort of an MPE (Multidimensional Polyphonic Expression) controller then defiantly check this one out.

You can even download additional content like extra wavetables and presets from HERE.

And if you’re a VCV rack user check out these Surge Modules.

Key Features:

– 3 Oscillators Per voice with 8 different Algorithms (Classic, Wavetable, FM and even Audio Input for Vocoding)

– Two Multimode filters with 8 different routing configurations and Feedback loop

– 12 LFOs, Multistage Envelopes and step sequencers for maximum modulation capabilities.

– 8 effects units (Delay, Reverb, Chorus, Phaser, EQ, Distortion, Conditioner (EQ, stereo-image control, and limiter), Rotary speaker, Frequency shifter, Vocoder)

– Adjustable Screen Size, Custom Scales (.scl files) and MPE control

Key Features:

– 2 Oscillators with cross-modulation and built-in Unison engine per oscillator

– Tunable Feedback section

– Build-in Arp, Stutter, Delay, Reverb and Distortion effects

– Separate Formant filter alongside a classic multi-mode filter

– 2 Mono LFOs one Poly LFO, Mod Envelope and a Step Sequencer all easily routable to anything thanks to Helm’s modulation system

This is donation based but if you really want you can put $0 and click Remind Me to download the synth for free.

Tyrell N6


Described as a “Compact, Sporty Synt”, this one is developed by the plug-in powerhouse U-He who is in charge of some legendary synths like Zebra and Diva.

So we can rest assured this one is a mini beast of its own. The twin filters are based on the early version of the Diva filters so they sound warm and analog with a mix spread for stereo imaging. It comes with over 600 presets.

Tyrell is the name of a project by the German online magazine After a reader survey, ideas for a low-cost hardware analog synth came about. Based on a design similar to Roland’s classic Juno 60.

The built-in chors effect is fat and wide reminds us of the famous Juno chorus.

Key Features:

– Virtual analog oscillators with classic architecture (Mix style oscillators, sub, noise, ring, and feedback)

– 2 LFOs with 8 waveforms and multips triggering options

– Twin filter related to Diva (early model)

– Unison with up to 8 voices

– Analog-type ADSR envelopes, loopable or LFO-triggered

– Modulation matrix with depth modulation from expression controls

– Chorus effect with 3 modes

– Skinnable and resizable UI

Developed by Digital Suburban. This is a Yamaha DX7 emulation. A legendary FM synth from the 80’s to create eerie pads, bell-like sounds, and modern growl/Reese/neuro bass.

It can be a complex synth to program but does only contain one window which makes sound design work easier and comes with packed with a lot of great presets. Features 6 operators (FM Oscillators) each with its own envelope and waveshaping section. The Envelopes are very interesting as they have 4 different stages with separate amount controls. There is a very simple Filter and one LFO but most of its power comes from the relationship between the different oscillators.

You can even use the original DX7 manual for some reference for this plugin.

Key Features:

– 3 Engine Types

– 32 routing algorithms

–  The sound engine music-synthesizer-for-android is closely modeled on the original DX7 characteristics

– One Singal window with most parameters being automatable

– Fully supports DX7 input and output Sysex messages; including controller change. This means that you can use this with a native DX7/TX7 as a patch editor and SysEx manager

– Each operator have a realtime VU meter


2500+ presets can be downloaded HERE

Now in Version 4, Tunefish is a hybrid additive synthesizer written with ridiculous compact code (1okb). In version 4 (check version 3 HERE for a different synth) the modulations are now visualized which makes working with this synth so much easier.

It was originally developed to accompany real-time 3d animations with music, which are then presented at computer art festivals called demoparties. For more information about the developer visit their website.

The amount of effects you can stack alone is a source of inspiration. Sperate filters for maximum sound manipulation and a good collection of factory presets. It has a built-in harmonics and waveform display that is great to help you understand what is happening to the sound as you play with the Oscillator section.

Key Features:

– Additive synthesis based wavetable generator

– Separate Low-Pass, High-Pass, Band-Pass and Notch filters

– Harmonics and Waveform displays

– Analog Pitch Drift (Slop)

– Up to 10 voice unison
