NTS-4: A Build-It-Yourself Analog Performance Mixer for Hardware Setups

Six channels, built-in effects, USB-C audio and MIDI, steel chassis. Ships as a DIY kit. No soldering necessary. Ready to use in minutes.

Tokyo, Japan, July 10, 2026 — KORG announced the NTS-4, a compact analog performance mixer kit designed for hardware setups built around the volca series, NTS instruments, Eurorack modular gear and desktop synths. Launching July, 10th 2026 at authorized dealers worldwide.

The NTS-4 is the fourth edition in the Nu:Tekt series. Like those before it, NTS-4 requires self-assembly that only takes minutes. What you end up with is a six-channel, palm-sized desktop mixer built for extended use in the studio, on stage or on-the-go.

Every channel has its own CUE and MUTE buttons. CUE routes the channel privately to headphones before it goes into the live main mix; useful for monitoring in a live set and for transitions that need to be set up without the room hearing it. MUTE cuts the channel instantly. Together CUE and MUTE are controls that make NTS-4 feel like a performance mixer rather than a routing box.

Six channels: four stereo minijack inputs and two mono minijack inputs compatible with Eurorack-level signals. An internal attenuator on the mono inputs switches between line and Eurorack level, making it a direct integration point for modular rigs without additional hardware. Dedicated stereo SEND and RETURN connections handles external effects. MAIN L/R outputs use standard unbalanced ¼” jacks. Capable of processing up to 10 audio signals, NTS-4 can work as the center of your hybrid hardware setup.

Each channel has a SEND FX control with seven built-in effect options: delay, ping pong delay, two hall reverbs, two slap reverbs and chorus. The MAIN output runs a TOTAL FX engine with ten options: low-pass filter, high-pass filter, isolator, flanger, phaser, decimator, drive, distortion, compressor and limiter. Two independent stereo effect engines running simultaneously; SEND FX for spatial depth per channel and TOTAL FX to shape the full mix. USB-C can handle both power and audio. 48kHz, 24-bit to a Mac, PC or mobile device. Record a performance directly to a phone. Stream a live set. Route MIDI from a DAW through the dedicated MIDI OUT jack to hardware.
