Hey guys, I wanted to share my top 6 free synth VST plugins which I love using in 2025, I hope that my list of these free synth VST plugins will help many music producers and beat makers.

Some of these synth free VST plugins are very advanced and come with tons of features and settings, sometimes it makes me wonder, how the heck are some of these VST plugins free? That's how good some of these are.

There are tons of free VST plugins online, but I wanted to highlight my 2025 selection. So, if you are looking for free Synth VST plugins, check out my selection below;

1. Vital VST 

Vital VST is a free virtual synth instrument, comes with tons of keys, pianos, leads, and tons of free presets, overall this a great advanced wavetable synthesizer with some great advanced features and modulation settings. Makes this my number one go to choice when it comes to free synth VST plugins in 2025. The quality and functions of this plugin is very similar to Serum VST.

2. Tyrell N6 

The free version of Tyrell N6 is simply amazing, it comes with tons of leads, pads, keys, FX, other experimental instruments as well as some cool soundscapes and gated-sounds. This free synth has been well-developed and designed, this plugin is quite low on CPU and simply provides some excellent virtual instruments for any music production purpose.

This plugin has been widely used for over many years, and has made it to my top 2 on this 2025 free synth list. I have made some epic beats using this synth, and it's well worth trying this one out.

3. K1V VST

The KIV is as good as the old school Nexus VST, It's simply packed with over 1000s of different virtual instrumental sounds ranging from pianos, harps, brass, leads, keys, percussions, drums, experimental synths, leads, guitar virtual instruments and so much more.

When I first downloaded this plugin, I was simply blown away with the amount of sounds that are inside this rompler style virtual instrument, some of the virtual instruments will require post edit effects such as EQ, compression and reverbs, but the quantity of virtual instrument choices are simply mind-blowing.

The K1V has made it to my top 3 list in, 2050 must have and must try synth VST plugins.

4. Romplay 2

Packed with over 140 free synth instruments, this rompler is another great addition to any music production browser library. Comes with some amazing leads, pads, keys (pianos), synths, textures and FX. I was quite surprised when I installed this inside my DAW, quite amazing on how such simple design, basic looking plugin, outputs such unique and high quality sound outputs. 

I highly recommend trying this one out guys.

5. Charlatan 3

When it comes to virtual analog synthesizers, Charlatan 3 has come a long way from its previous older version, I have used Charlatan 3 to compose some epic beats at the start of this year. This VST plugin comes with around 60 free virtual instruments, but some of these sounds are simply amazing.

Once again, I highly recommend trying this free VST out, the sound quality of this plugin will have many music producers in a wow form of situation, it sounds quality, and it's free.

6. Aeolian Meditation 

Aeolian is an addictive style synthesizer which comes with around 120 free virtual instrumental presets, the design of this plugin has been well constructed and again sound quality is decent. I am quite surprised that not many music producers and sound designers are simply not aware of this free Synth plugin. 

I had to add this to my list of my 9 most recommended synths for 2025. This free synth plugin is simply underrated, and I believe it should be getting a lot more attention that it's currently receiving. I highly recommend downloading and trying this one out. 

I hope that my selection of these 6 plugins will come in handy when it comes to music production and free synthesizer style virtual instruments. 

This is my recommended selection for 2025.
