Korg SQ-1 Step Sequencer (CV/MIDI Controller)

The Korg SQ-1 Step Sequencer is a compact, performance-oriented hardware sequencer designed for controlling analog synthesizers, modular systems, and MIDI gear. Built for hands-on sequencing and experimental music creation, it bridges the gap between classic analog CV/Gate workflows and modern digital MIDI environments, making it a flexible tool for studio production and live performance.

At its core, the SQ-1 features a 2 × 8-step dual sequencer architecture, allowing it to operate as two independent 8-step lanes or combine both rows into a single 16-step sequence. This flexible structure enables users to create evolving patterns, polyrhythmic sequences, parameter modulation tracks, and real-time performance variations with immediate tactile control.

The SQ-1 is designed around intuitive step buttons and a minimal interface that encourages improvisation. Each step can be activated or deactivated, reordered, or randomized depending on the selected mode, allowing users to reshape sequences on the fly without menu diving or complex programming workflows.

One of its key strengths is its extensive CV/Gate connectivity, which includes dual CV outputs and gate outputs capable of controlling analog synthesizers and modular systems. It supports both V/oct and Hz/V standards, making it compatible with a wide range of classic and modern synths, including Korg’s MS-series and other semi-modular systems.

In addition to CV control, the SQ-1 also provides MIDI output via USB and TRS adapter, allowing it to function as a bridge between analog and digital workflows. This makes it equally useful for controlling hardware synths, DAWs, and software instruments in hybrid setups.

The sequencer supports multiple playback modes including alternate, order, parallel, and random variations, enabling both structured composition and generative sequencing approaches. These modes can drastically alter how patterns evolve, making the SQ-1 a powerful tool for experimental rhythm creation and live performance variation.

Compact and battery-powered, the SQ-1 is designed for portability and integration into mobile setups. It can also be powered via USB, making it suitable for laptop-based music production or standalone hardware rigs. Its rugged build and minimal footprint make it ideal for travel, live sets, and modular performance environments.

Sequencing Workflow & Performance Control

The SQ-1 emphasizes immediacy and performance-driven sequencing rather than deep menu-based programming. Users can quickly build patterns by toggling steps on or off, adjusting pitch per step, and modifying playback behavior in real time. This encourages spontaneous composition and live improvisation.

Its sequencing modes allow for both predictable and generative behaviors. In ordered modes, it behaves like a traditional step sequencer, while random and alternate modes introduce evolving, non-linear patterns ideal for experimental music and ambient textures.

CV/Gate & Modular Integration

The SQ-1 is particularly powerful in analog and modular environments thanks to its dual CV/Gate outputs. It can control pitch, gate, and modulation parameters across multiple devices simultaneously, making it a central hub for semi-modular and Eurorack-style systems.

Support for both V/oct and Hz/V standards ensures compatibility with a wide range of synthesizers, including legacy Korg instruments as well as modern modular systems.

MIDI & Hybrid System Control

Beyond analog control, the SQ-1 also functions as a MIDI sequencer via USB and TRS connection. This enables integration with DAWs, software instruments, and modern hardware synths, making it suitable for hybrid production setups that combine analog sequencing with digital workflows.

Portability & Design

The SQ-1 is designed for portability, featuring a lightweight chassis and battery-powered operation. Its compact footprint makes it ideal for mobile setups, live performance rigs, and minimalist studio configurations where space efficiency is important.

Ideal For

• Modular and semi-modular synthesizer users
• Electronic music producers seeking hands-on sequencing
• Live performers building generative or evolving patterns
• Artists integrating analog and MIDI workflows
• Sound designers exploring experimental rhythm and modulation

The Korg SQ-1 Step Sequencer delivers a simple yet powerful approach to hardware sequencing, combining analog CV control, MIDI integration, and performance-driven design into a compact tool built for creativity, experimentation, and real-time musical control.
