Korg NTS-4 Performancer Mixer

The Korg NTS-4 is a powerful and adaptable performance mixer, with the flexibility of the Nu:Tekt series.

Featuring six channels, integrated effects, and USB audio/MIDI connectivity, it's built to seamlessly connect and mix with the Korg Volca series, NTS instruments, modular gear, and other desktop synths, making it easy to blend sounds, build soundscapes, and perform, whether it be in the studio or on stage.

Six-Channel Mixer for Complete Hardware Synth Setups

It arrives with four stereo channels and two mono channels, so you can combine multiple instruments into a single performance rig that supports up to 10 total audio signals.

Each individual channel on the NTS-4 includes level control, CUE monitoring, and FX send, allowing you to mix on the fly while controlling your performance. The 3.5mm mini-jack inputs support Volca units, NTS instruments, and other desktop gear.

Eurorack and Modular Synth Integration Made Simple

To provide seamless integration with Eurorack systems, each mono input supports both line-level and modular-level signals via a switchable attenuator. There are also dedicated SEND and RETURN connections so you can bring in external effects and expand your tonal spectrum with beats, bumps, and boings.

Built-In Effects for Creative Sound Design and Mixing

Two independent stereo effects engines provide per-channel SEND FX for spatial processing, while a master TOTAL FX section shapes the entire mix. You can then bring in effects such as delay, reverb, modulation, drive, and compression, which will add layers, depth, and structure to your sound.

Live Performance Controls for Dynamic Mixing

For live performances or recordings, each channel features dedicated CUE and MUTE controls. You'll be able to preview the sounds through headphones before adding them into the mix, or create instant drops and transitions with responsive muting.

USB Audio, MIDI, and DAW Connectivity for Modern Workflows

USB-C delivers 24-bit audio and MIDI connectivity for seamless recording, streaming, and DAW integration. Combine hardware and software workflows, or record directly to your computer or mobile device with ease.

MIDI received via USB can be routed through the dedicated MIDI OUT to control external gear, while standard 1/4" outputs provide dependable connections for both studio setups and live performance systems.

Compact DIY Performance Mixer Built for Studio and Stage

Despite being a compact unit, its steel body provides a rugged foundation that will protect it against the rigours of regular gigging and studio time. As part of the Nu:Tekt series, the NTS-4 is a simple DIY kit that assembles easily.

Once built, it becomes a durable, high-quality performance mixer ready for long-term use. The NTS-4 is built to sit at the centre of small hardware setups, reducing cable clutter and simplifying routing so you can focus on performance.
