Created by the same engineers responsible for the Commodore 64 - considered the best-selling computer of all time - Ensoniq’s SQ80 was up against stiff competition.

At the time of its release, the digitization of hardware synthesizers was well under way - but it went on to become a cult classic.

Here was a digital synthesizer that offered a degree of warmth and character usually reserved for its analog peers; flexible voice and modulation controls that didn’t require 10,000 hours of practice to program; a workhorse keyboard that produced an unprecedented array of timbres to suit any style, without the stellar price tag of similarly capable instruments.

After finding success with the Commodore 64 computer, former MOS Technology engineers Robert Yannes, Bill Mauchly, Bruce Crockett, David Ziembicki, Al Charpentier, and Charles Winterble spent several years on projects that ultimately didn’t materialise. The best selling computer of all time was a tough act to follow.

Their debut 1985 release, the Mirage, was a sampling keyboard that entered the market at considerably less than the dominant samplers of the time like the Fairlight CMI. Its affordable price tag came at exactly the right time, so success was all but guaranteed. Their next release, the ESQ-1, cemented the company’s place as worthy contenders in the synth arena.

By the time Ensoniq released the SQ80 - an updated version of the ESQ-1 - the digital synth market was saturated. Pioneering Japanese manufacturers were dominating, with releases like the Roland D-50 and the Yamaha DX7 already in the world's top studios and on the biggest stages.

The SQ80 was up against stiff competition. And yet, during a time when synthesizers were becoming increasingly complex, and therefore difficult to program, Ensoniq had the upper hand. Simple menus, a clear screen, and clearly assigned buttons meant that crafting your own sound was quick, fun, and versatile. Compared to the leading Korg M1, the SQ80 was a breath of fresh air for keyboardists. The fact that its proprietary digital circuitry was combined with a Curtis CEM 3379 filter & amp chip meant that its sound was unique too. Rather than glassy and precise like other digital offerings, it was crunchy, loud, and inconsistent.

It was this distinct formula that, ultimately, led to the SQ80 being considered a classic instrument. Its imperfect tones, featured on numerous ‘80s & ‘90s hits, soundtracks, and performances, are as nostalgic and edgy today as they ever were. SQ80 V brings them to your DAW in all their former glory, complete with additional enhancements modeled on Ensoniq’s later releases like the VFX.


SQ80 V’s unique voice is all about combining and manipulating waveforms.

Each of its 3 oscillators can be assigned a different waveform; SQ80 V unites classic waveforms from the original built-in library with hundreds more that we’ve added, ranging from the familiar to the abstract. The resulting range of sounds at your disposal is simply enormous; soft moving string pads, plucky pulse width basses, glitchy industrial percussion...

Just a small selection of the variety of sounds you can attain with SQ80 V, thanks to its diverse library of available waveforms.

SQ80 waveforms

The Complex Oscillator generates harmonically rich tones by folding a waveform’s peaks and valleys back on themselves.


An additional technology taken from Ensoniq’s follow-up generation of synthesizers, including ‘Transwaves’, a pioneering form of wavetable application.

ESQ-1 hidden waveforms

ESQ-1 preceded the SQ80, but had the same software. The same ‘hack’ was applied to produce a new selection of unique waveforms.

SQ80 hidden waveforms

By ‘hacking’ the original SQ80’s software, users unearthed a series of unpredictable waveforms made entirely of manipulated code.

Shades of

SQ80 V’s unique voice begins with its 8-bit oscillators and endless hybrid waveform combinations.

It’s when these components collide with its emulated CEM 3379 analog filter that it truly comes into its own. By processing digital sounds through its emulated analog filter and amp, SQ80 V can inject organic imperfections, crunchy harmonics, and tangible lo-fi distortion into your modern mixes.

Using our proprietary TAE® technology, we remodeled it in unparalleled detail to bring you a virtual instrument that sings, barks, and growls just like the original hardware.

Hear the richness of SQ80 V's modeled CEM resonant low pass filter and how well it complements the digital voices.

Layer upon

From the immediacy of its controls to its games console aesthetic, SQ80 V is as charming, edgy, and accessible as the real deal. Use it in your DAW or as a standalone instrument and, quite literally, make waves.


An authentic experience

The main interface is stripped down, as with the original, with a mini display menu providing instant access to your main voice controls, including tuning, waveform selection, octave switching, and more.




01. Oscillator triple threat

In the Synthesis tab, you’ll find more detailed controls for SQ80 V’s 3 oscillators, each with a dedicated DCA (amplifier) and hundreds of waveforms to choose from. This simple architecture is comparable to classic analog synths, making it ultra-accessible despite its complex sound. And, just like the original, you can explore unique hard sync and AM (amplitude modulation) configurations to unlock more abstract sonic behavior.

02. Analog output

Where digital meets analog, magic happens. SQ80 V features a meticulously-modeled Curtis CEM 3379 chip that provides the beautifully warm resonant analog filter and stereo amplification stage. Better still, we implemented subtle analog dispersion to reproduce the nuanced ever-changing behavior of analog circuitry for a truly organic sound.

03. Movement and modulation

Ensoniq’s instruments were known for providing a more familiar synth architecture than many of their digital peers, closer to that of an analog synth in many ways. SQ80 V replicates and enhances this familiarity in detail so you can craft your own evolving, pulsing, and rhythmic sounds in no time: 4 multimode polyphonic envelope generators, 3 LFOs with 6 waveforms, 8 MIDI sources, and even a dynamic modulation mixer.

3-Oscillators Versatility

Analog Dirt Output

Even a simple filtered sawtooth waveform can sound beautifully grainy and lo-fi thanks to SQ80 V's emulated analog filter and output.


A demonstration of how a single sustained note can become an interesting rhythmic and melodic pattern in itself, simply by applying SQ80 V's MSEG modulator.


Getting SQ80 V mix-ready is as easy as hopping over to the Effects tab. A familiar but powerful array of 15 effects add the final piece to its end-to-end sound design puzzle. From modulation to dynamics, configure the effects section in series or parallel to refine your patch into a finished product.

What we

SQ80 V strikes the perfect balance between ‘80s cult classic and modern production workhorse with character.

To achieve this, we added hundreds more waveforms and retrofitted its architecture with a number of extra creative features - without compromising its distinct retro charm.

The arpeggiator

Introducing an arpeggiator to SQ80 V’s curious sound equips it for easy performance and melody creation. A classic component with the familiar controls, including arp direction, sync, octave range, and hold. Just turn it on and enjoy free-flowing lo-fi sounds that fit right into your mix.


SQ80 V offers up to 16-voice polyphony - twice that of the original hardware instrument - but we couldn’t resist adding an 8-voice unison option. Stack up those oscillators for enormous basses, gritty percussion, and ultra-dense lead sounds.


When it comes to classic synths and keyboards, the true charm often lies in the details. We went a step further than emulating the SQ80’s sound and interface by introducing dispersion - meaning subtle variations and inconsistencies in the behavior of its emulated circuitry. No two notes will ever be exactly the same, bringing a truly unmatched organic sound.

Envelopes expanded

To further shape the attack, duration, and evolution of your sounds, we upgraded SQ80 V with 2 additional envelope modes: DADSR and MSEG. The former adds a delay stage to the traditional ADSR for staggered strikes and interesting rhythmic patterns. The latter is a fully-customizable looping function generator for painting envelopes your own way.

The Mod Mixer

Combine any 2 modulation sources, from envelopes to keyboard controls, to distort, mangle, and refract your patches in interesting and unexpected ways. With 6 different modes of modulation mixing, the combination possibilities are enormous - as are the potential sonic results.

MPE compatibility

SQ80 V supports MPE-compatible controllers for an advanced expressivity experience. Create dynamic performance patches and textures that can respond in numerous ways to a single keystroke.


Enjoy perfect tailor-made sounds from the offset with SQ80 V’s expertly-designed library of 160 presets, including 40 replicated from the original instrument.

From metallic industrial percussion to synthetic keyboard patches, you’ll find a sound that suits you in no time.

80 Squares


80 Squares brings us back a good twenty years as it is heavily influenced by some key artists in the techno and house scene that we listened to a lot in early 2000. The SQ80 V delivers the ingredients for the track perfectly, as this synth was used a lot in the scene.

87 Summer Sunset

Maxime Audfray

A retro synthwave track with a lot of 80's action, showcasing the ability of the SQ80 V to trigger strong nostalgia response from the VHS era. All sounds present in this demo (even the drums!) are from the SQ80 V, with only a little bit of EQ and compression.

Planete X

Maxime Desormieres
