The Korg NTS-4 is a compact DIY performance mixer designed to bring desktop synths, grooveboxes, modular systems, and computers together into one streamlined setup. Offering six channels, integrated stereo effects, USB audio and MIDI, and flexible connectivity, it provides a powerful hub for modern hardware-based music production and live performance. With four stereo inputs and two mono inputs, the NTS-4 can accommodate up to ten audio signals simultaneously. The mono channels feature selectable line or modular-level operation, allowing direct integration with Eurorack systems, while dedicated stereo send and return connections make it easy to incorporate external effects into your workflow. Two independent stereo effects engines provide creative processing throughout your mix. Per-channel SEND FX includes delays, reverbs, and chorus, while the master TOTAL FX section offers filters, modulation, drive, distortion, compression, and more for shaping your entire performance. Dedicated Cue and Mute controls on every channel make transitions, monitoring, and live performance intuitive and immediate. USB-C connectivity enables 24-bit / 48kHz USB audio alongside MIDI transmission, making it simple to integrate hardware with DAWs, mobile devices, and streaming setups. Housed in a durable steel chassis and assembled by the user as part of the Nu:Tekt series, the NTS-4 is designed to become the central mixing hub for compact electronic music systems.
