Best Free Synth VST Plugins – Make Great Sounds for Free!

So, you’re looking for the best synth VST plugins? Look no further, because I’ve got some great ones for you right here.


Datsounds OBXD

This synth, which is an emulation of the famous Oberheim OB-X, OB-Xa and OB-8 synths, seems to be good for creating nice synthetic sounds. It can also produce some rather weird squishy synth sounds.

Green Oak Software Crystal

This soft synth is semi-modular and uses both subtractive and FM synthesis. It’s capable of producing some quite eerie sounds once you start fiddling around with the many different controls.

u-he Triple Cheese

This one is great for making flutey leads or atmospheric pad sounds. Nice and reverby. It can also do some nice spacey organ sounds and some weird synth squelches.

Togu Audio Line TAL-NoiseMaker

The name of this synth probably doesn’t do it justice. Yes, it can create some harsh sounds, but it does more than that. It’s not just for making noise, it’s for making some great synth sounds too.

u-he Tyrell N6

This seems to be good for making great synth bass sounds but can also do goo organ-like and mallet and bell type sounds. It’s very metallic and glassy sounding but can also do some quite spooky sounds and weird warbles.

Digital Suburban Dexed

Nice syth brass sounds, good percussive noise, pleasant bell type sounds warm pads and some harsh metallic synth sounds. There’s quite a lot going on here.

Ichiro Toda Synth1

Great for sci-fi type synth bleeps and sequences. Tends to sound quite metallic. Could be good for retro synth sounds.

Hermann Seib WaveSim

This is a software version of the PPG Wave. I quickly started to recognise the sound of this synth. I’m pretty sure Tangerine Dream used it on their album Exit from 1981, which must have been when the synth first came out. Now you can replicate those kinds of sounds for free!

Siegfried Kulmann SQ8L

I love that reverby sequence near the beginning of this video. It would be great to make a nice melody with that. But then it gets transformed into something quite different. It seems you can make quite a wide range of sounds with this synth, some of them soothing, some of them very electronic, some funky, and some atmospheric and spooky. Interesting organ-like sounds.

Tone2 FireBird 2

Those big organ-synth chords at the beginning would really suit a modern EDM track. Yet this can also do nice flutey sounds, electronic squelchy sequences, and drifting atmospheric pads. This synth would be really good for making a lot of modern music.

Mark Henning Anamark

This one seems to be best of for beeps and squelches. Quite a simple-sounding synth really, but could sound good in the right place.

Download >>

BrainStormer by Roazhon DSP

I imagine this one being great for making arpegiated synth sequences and basslines to sit underneath your other synth sounds.

Download >>

Lokomotiv by Archetype Instruments

The controls of this software synth seem rather bleak and minimalist, but it can certainly make some interesting sounds. They sound quite metallic and harsh, which could suit some music well.

Tunefish 4 by Brain Control

I love the sound of this! Sounds like you can make some really nice electronic music using this synth. It’s quite amazing that something sounding so good is available for free. Of course, the tune made with it in this video helps too.

    What an amazing array of free synth plugins. I didn’t even know you could get these for free and thanks for giving me the opportunity of trying them out.
    I really like the u-he Triple Cheese. As you describe, it is really beautifully atmospheric and ideal for meditating and relaxing by.
    As I’m thinking about purchasing a new keyboard I was pleased to find the Yamaha MM8 review on this site. It looks like a keyboard to add to my list of possibles. Thanks, nice site. Ches

      Thank you, Ches. I’m glad you enjoyed it and found it helpful. Yes, the MM8 is ideal for beginners.

    Some of these plugins look really handy – especially since they are being given away free at the moement. I only have one question – are they 64 bit friendly in the Ableton way? You probably know by now that the newer versions of Ableton are dreadful at recognizing certain free plugins – I wish I’d stuck with the 32 bit version t times!

      Ahh, that’s a good question, Chris. To be perfectly honest, I’m not entirely sure. I will have to have a look into that…
