Sound Effect Synths
Synths are one of the most entertaining things to use on your tracks. They sound fantastic, and by using them, you can create ambient chimes, warm chord sounds, weird & psychedelic sounds, & much much stuff like that.
But the issue with analog synths is that they are expensive & too big. And that’s where synth plugins come in. All you’ve to do is load them in your DAW (Digital Audio Workstation), and you’re ready to rock.
In the past, it was impossible to imagine that so many quality tools used for mixing could be available at no cost. But now there are many free plugins available on the internet than ever before.
So, how can you know which free VSTs are worth installing? And which VST’s will suit you the most? We’ve got you covered! Here’s the list of the best 10 Free VST Synth Plugins available that sound fantastic!
So Let’s get started.
Synth1
Synth Synth Analogue/Subtractive
Synth1 is one of the most used and most popular long time free choices for aspiring producers to create music with a plugin synthesizer. It’s a very decent synthesis powerhouse with lots of potential on one side, & also a bit of unexpected trouble missed opportunities.
The look of Synth1 is quite rough visually, but it’s a well-organized & functional plugin. Synth1 is resizeable up to 250%, and it’s perfect for modern high-resolution displays. You can also set the color of the text & the panel separately.
Synth1 updates are infrequent ( the last update was back in 2014 for Windows operating system, & it’s still called ‘beta’ today), but the Japanese author keeps adding GUI optimizations & charming new features.
Synth1 has got an astonishing abundance of presets. By searching on the internet, you can easily download tens of thousands of presets in organized preset packs. It’s worth skipping essential factory banks/presets & spent more of your time finding those little inspiring gems.
Features:
- FM modulation, 2 Oscillators, Ring Modulation, Sync, Modulation Envelope.
- 2 LFOs (synchronized with host).
- Four types of filters, distortion.
- Arpeggiator (synchronized with host).
- Tempo delay (synchronized with host), stereo chorus/flanger.
- 16 notes polyphony.
- Legato mode, portamento.

- Thoroughly optimized for light CPU load using SSE instructions, etc.
Arppe2600va
Synth Synth Analogue/Subtractive
The number 2 in our list of the best 10 VST synth is Arppe2600va. It’s based on ARP’s legendary semi-modular analog monosynth! This multi-functional softsynth sounds very close to the original ARP 2600. Like the original one, its mono synth (no polyphony).
But also like it’s the original version, it has got a multitude of Frequency Modulation options and by which you can create some awe-inspiring sound effects.
Features:
- It has PWM, Sample & Hold, Ring Modulation, virtual Spring Reverb, & a dedicated Noise Generator.
- Filter Color (to adjust LowPass & HiPass filter types).
- Oscillator Sync (Original Arp 2600 didn’t have Oscillator Sync and Filter Color).
- You can get up to 12 patch routings with a very user-friendly (and visible!) drop-down menu interface.
- Arppe2600 started with the version 2.0, but now Arppe2600va is purchasable via a cleverly designed Mod Matrix!
- Instead of messy virtual of cables cluttering up the screen, All controls in the Arppe2600va are mapped to MIDI CC#’s, & you can override the default settings by using the MIDI Learn feature.
- You can use it as a pure stand-alone synth (.exe file included), or you can also copy the DLL into your favorite DAW or sequencer’s plugin folder.
Requirements:
- VSTi Format
- Windows System
SQL8
Synth
The SQ8L (L stands for Light) is a free demo version of the forthcoming SQ8X (X Ffor eXtended) version. It’s a software model of Ensoniq’s classic 1980s synth SQ80. SQ80 contains three digital wavetable oscillators for each of its eight voices fed through analog 4-pole lowpass filters (-24dB gain) with resonance. Sound parameters in SQ80 can be modulated by four envelopes, 3 LFQs & several MIDI sources.
SQ80 has also got a predecessor, and it’s the ESQ1, which can do almost the same things as SQ80. Although the technology may seem obsolete, these synths can gene ate a wide variety of extraordinarily usable & exciting sounds.
Because of the lo-fi oscillators & the analog components, it can sound very digital & dirty, but also, this synth is very analog & warm. And that’s very good because modern synths often lack to sound rather clean.
Limitations:
- Polyphony limited to only eight voices.
- Universal MIDI controllers (Pan, Master Volume,…), by default, do not affect & must be programmed as modulators.
- LFO humanization not implemented.
- No internal sequencer (and there will never be one).
- No Split/Layer to combine several sounds.
The full version SQ8X will get the following additional features.
Features:
- Combinations of up to 4 single sounds.
- Adjustable polyphony (far more than eight voices).
- New Filter algorithms with different modes such as bandpass, lowpass, highpass.
- Improved GUI
- Different routing modes for the filters: parallel, serial, split. & the second FILTER.
Noisemaker

Chimera
Synth Synth Analogue/Subtractive
Chimera is a popular noise-driven synth and a free VST synth by Majken. The sounds that Chimera generates are based on white noise filtered into notes by resonant bandpass filters. And as a result, we hear some organic sounds ranging from warm pads to atmospheres with wind & water elements.
This VST is a perfect pick, especially for ambient & chill-out. It’s a very smooth and beautiful sounding synth. It’s an experimental synth that uses subtractive Synthesis in a new way. White noise is sent through a series of few narrow bandpass filters, which are controlled by pitch.
The filtered noise of Chimera is used as resonant sinewaves to create atmosphere organs, pads, and percussive sounds. In simple words, everything we hear from Chimera is white noise filtered into music (in realtime). Some of the features of Chimera VST are as follows.
Features:
- It has more than 50 included presets.
- Has a unique synthesis method.
- It’s built-in soft clipper distortion & has a 2-tap stereo delay.
