Sequential is an iconic American synthesizer manufacturer, renowned for its pioneering contributions to the development of analogue and hybrid synthesizers. Founded in 1978 by Dave Smith, the company (initially known as Sequential Circuits) revolutionized the music industry with its Prophet-5, the first fully programmable polyphonic synthesizer with digital patch memory. This groundbreaking instrument allowed musicians to store and recall sounds, making it a landmark development in music technology. The Prophet-5 became a defining instrument of the late 1970s and 1980s, widely used by artists across genres, from pop and rock to electronic and film scoring.

In recent years, under the leadership of Dave Smith, Sequential has continued to push boundaries with modern re-imaginings of classic instruments as well as entirely new designs. Notable products include the Prophet Rev2, Pro 3, OB-6 (in collaboration with Tom Oberheim), and the highly acclaimed Prophet-6—all of which blend vintage-inspired analogue circuitry with contemporary features like MIDI integration and digital control. Sequential’s synths are celebrated for their rich sound, robust build quality, and expressive interfaces, making them favourites among musicians, producers, and sound designers alike. The company remains a key player in the world of synthesizers, bridging the gap between vintage warmth and modern versatility.

Analog

An analog synthesizer is a musical instrument that generates sound electronically through the manipulation of voltage-controlled oscillators, filters, and amplifiers. Unlike digital synthesizers, which use computer processors to generate and manipulate sound waves, analog synths use voltage and electrical signals to produce a wide range of tones and textures. These synths are renowned for their warm, rich, and often unpredictable sound, making them a favorite among musicians and sound designers seeking organic and dynamic sonic capabilities. With their tactile controls and hands-on approach to sound shaping, analog synthesizers offer a unique and immersive experience for musicians exploring electronic music production.

Pianos and Keyboards

From expressive stage pianos to versatile MIDI controllers and classic electric keyboards, this category brings together everything you need to play, perform, and produce. Whether you’re after the weighted feel of hammer-action keys, the vintage charm of a Rhodes-style sound, or a compact keyboard to control your synth rig, you’ll find something here to suit your playing style. Ideal for both studio work and live performance, these instruments offer tactile connection and musical freedom across genres — from ambient textures to punchy techno stabs and everything in between.

Poly

The Poly line is associated with synthesizers that are capable of polyphonic sound, allowing musicians to play multiple notes simultaneously. These instruments often come with advanced features for sound design, such as layering, modulation, and built-in effects.

Polyphonic synthesizers are popular among composers and performers looking to create rich, complex harmonies or textures. Brands like Roland, Yamaha, and Sequential offer various polyphonic models, each with its own unique sound engine, making them versatile tools for live performance and studio production.

Synthesizers

At the heart of electronic music lies the synthesizer — a tool of limitless creativity. From fat analogue basslines and sweeping pads to gritty FM textures and modular experimentation, our range of synths covers every sonic territory. Whether you’re chasing vintage warmth, modern digital precision, or the hands-on joy of knob-per-tweak design, you’ll find something here to inspire. We stock everything from portable groove boxes and desktop mono synths to powerful polys and rare collector’s pieces — ideal for studio producers, performers, sound designers, and synth obsessives alike.
