Inspiration

The Ensoniq ESQ-1 is a special keyboard at UVI. Used by many on our team, including being a personal favorite of one of our founders, our USQ-1 had to be great. We’ve leveraged years of experience with this synth and put our hearts into creating a collection of sounds that we're proud of and that we’re sure you’ll enjoy.
Released in 1986, the Ensoniq ESQ-1 was one of the first affordably priced workstation-class keyboards on the market, combining an 8-voice, multitimbral digital/analog hybrid synthesizer and a featured 8-track sequencer. The ESQ-1's voice architecture allows customization of up to 3 digital oscillators, assignable to any one of 32 waveshapes, followed by a Curtis 4-pole 24dB/oct resonant low-pass analog filter and 15 routable modulation sources. The sound quality of the ESQ-1 is all-at-once digital, warm and unmistakably '80s - a true gem of the time whose sounds still ring with a brilliant depth and character.

Overview

Instrument

USQ-1 offers 268 selectable layers made from over 22,000 samples. To showcase the sonic potential we've included 400 all-new patches including everything from rich bells, strings and leads to thick basses, textured pads and modulating atmospheres. The versatile design of the ESQ-1 allowed us to create both classic sounds that you’d expect from a vintage-era synth and also modern patches utilizing more contemporary sound design techniques. All-in-all these sounds ring with a special "vintage digital" vibe that synths of this era, and the ESQ-1 especially, do so well.

USQ-1 | Showcase
The sounds in USQ-1 are detailed and powerful. Every patch began with sound design on the original hardware and was recorded at our main studio through the highest-quality processors and converters available. You’re not just hearing the output jacks of the synth, the entire signal chain was thoughtfully considered to create a rich and professional "finished record" sound that’s both mix-ready and inspiring to play.
Included presets can easily be edited or you can build your own patches from scratch. Authentic sounds from the ESQ-1 are presented in a dual-layer architecture allowing for the design of two custom oscillators each with independent wave selection of 268 layers, ADSR amp, multi-mode filter with envelope, pitch, portamento, stereo, LFO, multi-step and modwheel modulation assignments and an arpeggiator. At the end of chain is a capable effect bus loaded with UVI’s own processors, including a 3-band EQ, drive, chorus (Thorus), phaser, delay and reverb (Sparkverb) all with excellent sound-quality and a featherlight CPU footprint.
USQ-1 delivers that vintage digital magic that we fell in love with over 30 years ago: a bold and inspiring collection of sounds combining modern sound design technique with an unmistakable '80s flavor.

UVI has brought back a unique synth of lush sound and major improvements. Few synths have the sound, features and filters like these. To UVI: You guys did it again! My respects.

Having the original Ensoniq keyboard, USQ-1 is one to have! It sounds so great and immediately throws me back to those days! The sound is powerful and very full. I love the bass sounds on this! It went straight into my template the moment I heard it!

My first professional synth when I was 14 was an ESQ1. I still own that baby to this day! I know its sounds from top-to-bottom and I’m in love with the USQ-1, it's a perfect recreation of the original! Thank you UVI!

"UVI has elegantly simplified the UI to make the instrument highly accessible and quick to use."
"USQ-1 — especially in the context of UVI Falcon — is a terrific sounding, powerfully expressive synthesizer that will add intriguing colors to your synth mixes."
"There’s enough awesomeness packed into USQ-1 to keep you happy for a while. It can provide many parts for a piece of music from the bassline up."
"It’s got some grit! It’s the character you’re going for here, and UVI have captured it. And there’s a ton of presets!"
