Korg NTS-4: Compact Performance Mixer with Modern Hybrid DNA

Korg positions the NTS-4 as a compact, palm-sized performance mixer, specifically designed for modern hardware setups. Despite its small footprint, the video is quick to dispel any concerns about durability, highlighting a steel chassis and robust build. The device is shown to be highly portable yet sturdy enough to withstand travel, on-the-road knocks, and even the occasional drop from a table.

Assembly is a core part of the NTS-4’s identity, continuing Korg’s Nu:Tekt DIY lineage. The kit is presented as straightforward to assemble, with the promise that it only takes minutes rather than hours. Once constructed, the hardware aims to deliver the reliability required for both studio and live use, making it suitable for users who want a long-term addition to their rig.

The NTS-4 offers a total of six input channels—two mono and four stereo—all on 3.5mm jacks, making it inherently compatible with volcas, other NTS devices, and modular gear. Of particular interest are the two mono channels, which include internal jumpers for switching between line and modular levels. This enables direct Eurorack integration without the need for external interfacing, a feature explicitly highlighted as a boon for hybrid setups. Main outputs are standard quarter-inch, allowing for direct PA connection or sub-mixer roles in larger chains.

A stereo send/return loop is also present, supporting external FX integration via mini jacks. Performance features take center stage: every channel sports dedicated cue and mute buttons. The cue system enables headphone monitoring before signals hit the main mix, while mute buttons allow for live transitions, cuts, and drops—tools that are essential for hands-on, DJ-style performance scenarios.

USB-C connectivity is a major pillar of the NTS-4’s hybrid ambitions. The mixer can deliver 24-bit, 48kHz audio directly to a computer, phone, or tablet, enabling direct recording or live streaming without the need for an additional interface. This workflow is demoed as plug-and-play, supporting a range of modern devices.

MIDI is also handled via USB, with the mixer able to receive MIDI from a DAW and route it through its MIDI output to external hardware. This closes the loop between analog and digital gear, allowing for integrated control and signal routing in a single, consolidated mixer. Korg’s approach here is clearly aimed at users wanting seamless transitions between standalone and computer-based workflows.
