Korg NTS-4

A Compact Hub for Modern Hardware Setups

The NTS-4 fits the logic of modern machine-oriented configurations, where immediate control, reduced footprint, and real routing flexibility are sought. Its ultra-compact format, aluminum chassis, and design intended to accommodate multiple small machines make it a particularly coherent solution for volca ecosystems, NTS instruments, compact modules, and small desktop synths. It positions itself as a true control center for those who want to mix, process, and send their signal without weighing down their setup.

For Which Musicians and Uses?

This mixer is aimed equally at the beginner electronic musician building their first hardware setup and the experienced performer looking for a lightweight and quick-to-master tool. It will be especially comfortable in techno, house, ambient, electro, synthwave, modular experimentation, or hybrid live setups with grooveboxes, samplers, and compact synths. In the studio, it facilitates source organization and direct recording; on stage, it allows control over volumes, effects, and transitions with a simple and immediate gesture.
Modular system users will also appreciate its ability to interface with line or modular levels, avoiding bulky conversion solutions. For a mobile setup, a tight production desk, or a computer-free configuration, the NTS-4 offers a practical, musical, and genuinely effective solution.
