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.

Professional

A **professional synthesizer** is a high-quality instrument designed to meet the demanding needs of musicians, producers, and sound designers in professional settings. These synthesizers offer advanced features, robust build quality, and versatile sound engines capable of creating a vast array of tones. Professional synths typically include comprehensive modulation options, multiple oscillators, and high-quality effects, allowing users to shape and refine their sounds with precision. They often have premium components such as velocity-sensitive, aftertouch-enabled keyboards, durable encoders, and high-resolution screens for detailed editing. Brands like Nord, Moog, Roland, and Korg are known for producing professional-grade synthesizers that are trusted in live performance, studio recording, and sound design for films and games.

These synthesizers often come with extensive connectivity options, including MIDI, USB, and audio outputs, to integrate seamlessly into complex setups. Additionally, professional synths provide a range of synthesis methods—such as subtractive, FM, wavetable, granular, and physical modeling—offering musicians and producers the flexibility to explore various soundscapes. Their sound engines are designed to deliver rich and expressive tones, with deep control over parameters, making them suitable for complex arrangements or performances. Essentially, a professional synth is built for reliability, expressiveness, and adaptability, catering to those who need top-tier sound and performance capabilities in their creative work.

Synthesizer

A synthesizer, often abbreviated as synth, is an electronic musical instrument that generates and manipulates sound electronically. Synthesizers create sound through various methods, including subtractive synthesis, additive synthesis, frequency modulation synthesis, and wavetable synthesis, among others. They typically feature oscillators to produce raw waveforms, filters to sculpt the timbre, envelopes to shape the sound’s amplitude, and modulation sources to add movement and complexity.

Synthesizers offer a vast range of sounds, from classic analog tones to futuristic digital textures, and are used in a wide array of musical genres, from electronic and pop to rock and film scoring. With their versatility and expressive capabilities, synthesizers are essential tools for musicians, producers, and sound designers seeking to explore and create innovative sonic landscapes.
