Introducing Ensoniq ESQ-1 by Cherry Audio

Ensoniq® ESQ-1 by Cherry Audio is a virtual instrument synthesizer that brings back the spirit and sounds of the Ensoniq ESQ-1 polyphonic synthesizer with the utmost accuracy. The plug-in includes the original 32 waveforms, licensed from Creative Technology, to precisely recreate the 1986 ESQ-1 in software, enhanced with modern features to make it accessible to today's musicians and producers.

A Different Kind of 1980s Classic

In the mid-1980s, synthesizers were changing fast. Analog polysynths were giving way to sleek digital machines, FM synthesis was everywhere, and musicians were suddenly being promised the future in glowing displays and membrane buttons. Into this brave new world came the Ensoniq ESQ-1, a synth that didn’t quite fit this new futuristic vision.

A Digital Wave Synthesizer with an Analog Soul

The original ESQ-1 was a digital wave synthesizer with an analog soul, meaning that its oscillators were digitally stored waveforms rather than traditional analog circuits. Each of its 8 voices featured three Digital Wave Oscillators, drawing from 32 sampled and synthetic waveforms, which were then shaped by analog filtering (from the renowned CEM 3379 IC by Curtis Electromusic), four DCAs, four envelopes, three LFOs, amplitude modulation, oscillator sync, and a surprisingly deep modulation system.

It was also more than just a synth. The original hardware included a powerful eight-track MIDI sequencer, giving musicians a way to build complete musical ideas inside the instrument itself. Ensoniq described it as “two powerful devices” in one: an eight-voice, poly-timbral Digital Synthesizer and a flexible eight-track MIDI Sequencer.

What made the ESQ-1 special was the way it combined different worlds. Its digital oscillators could produce crisp, harmonically rich, unmistakably 1980s waveforms, but those waves didn’t just stay cold and shiny. They passed through a warm, characterful signal path that gave the instrument weight and a personality all its own. It could sound glassy, moody, brassy, metallic, lush, strange, or darkly cinematic.

The Cult Favorite That Never Wore Out Its Welcome

The ESQ-1 also arrived at an odd point in synth history. It wasn’t as famous as the Yamaha DX7, Roland D-50, or Korg M1. It didn’t become a single-sound cultural monument to a time and place in musical history. In other words, there’s no single cliché ESQ-1 preset haunting wedding receptions, documentaries, or sound design nostalgia packages. Instead, the ESQ-1 became something more interesting: a workhorse cult favorite with deep programming, a loyal following, and a sound that is still interesting because it was never overused.

Faithfully Revived After Four Decades

Just in time for its 40th Anniversary, the Ensoniq ESQ-1 by Cherry Audio virtual synthesizer brings every bit of the original's character back with unusual care. It isn't just a loose tribute to a vintage instrument with a familiar-looking faceplate. Cherry Audio worked directly with Creative Technology, the current owner of the Ensoniq intellectual property, to obtain official licensing for the original 32 ESQ-1 waveforms for this release. This is a critical part of the equation because these waveforms are the heart, soul, and raw material of the ESQ-1's sound, and here they reemerge as part of a modern virtual instrument built for today's musicians, producers, and sound designers.

Cherry Audio’s version also supports importing original ESQ-1 SysEx patches, allowing decades of user-created sounds and legacy patch libraries to find new life in software. For anyone with old ESQ-1 sounds, cartridge memories, or downloaded patch collections lurking on a drive somewhere, this is more than a convenience. It’s a small but miraculous act of synthesizer archaeology.

Classic Character, Modern Possibilities

At the same time, this uniquely inspiring synth is not limited to the sounds of the 80s. Cherry Audio’s ESQ-1 expands the original concept with two fully independent layers with flexible Whole, Layer, and Split performance modes, a modern modulation matrix, macro controls, a Motion panel with arpeggiator and sequencer tools, per-layer and global effects chains, and support for polyphonic aftertouch and MIDI Polyphonic Expression (MPE).

The result is an instrument that keeps the ESQ-1’s sonic heart intact while giving it the kind of immediacy and expression that modern software enables.

Where to Begin

If you’re new to the ESQ-1, the basic idea is simple: start with three digital wave oscillators, sculpt them with filter and amplifier stages, then animate the result with envelopes, LFOs, modulation, motion sequencing, and effects.

If you already know the original hardware, you’ll find the familiar architecture here, but with a lot more room to stretch out. The ESQ-1 was powerful, but it asked you to do much of your programming through a letterbox display, soft buttons, and a data slider. Cherry Audio’s ESQ-1 brings the power directly to the surface, allowing you to view settings across a handful of pages and access a more comprehensive picture of its signal path.

Cherry Audio’s ESQ-1 authentically captures the unique essence of this powerful instrument for the first time, enhancing it to meet the expectations of 21st-century musicians. Like the original, this virtual instrument skillfully combines digital and analog expressiveness in a way that is slightly unconventional, yet far more capable than its often-overlooked reputation suggests.
