Superbooth coverage tends to chase whatever’s loudest and strangest on the show floor, and this year that meant a veiled, deliberately mysterious new Korg synth pulling most of the attention. Quietly launched alongside it: the NTS-4, a new performance mixer in Korg’s Nu:Tekt DIY lineup, now shipping for $249/£189/219€ as a solder-free kit.

What’s actually on the unit
The NTS-4 is a 6-channel digital mixer — 4 stereo channels on 3.5mm jacks and 2 mono channels, the mono pair Eurorack-compatible with switchable attenuators — paired with a pair of quarter-inch L/R outputs for connecting to a full PA or monitor setup. Two independent stereo effects engines do the actual sound-shaping work: a per-channel SEND FX control for delay, reverb, and chorus, and a TOTAL FX engine sitting on the master output handling filters, modulation, drive, and compression across the whole mix. Every channel gets its own level, send, and pan controls plus dedicated cue and mute buttons — full monitoring and signal routing without reaching for a separate device. USB-C support adds 48kHz/24-bit digital audio transfer directly to a computer or mobile device for streaming or recording.
Why “solder-free kit” matters here
Korg’s Nu:Tekt line has built its identity around DIY assembly, but a mixer is a meaningfully more forgiving thing to build yourself than a synth voice — there’s no calibration-sensitive analog circuit whose sound depends on getting a component exactly right. That makes the NTS-4 a lower-stakes entry point into the DIY hardware world than most of Nu:Tekt’s synth kits, while still producing something genuinely useful in a working setup rather than a novelty build.
Why this is worth more attention than the “sneaky launch” framing suggests
A mixer with real effects built in and Eurorack compatibility fills a specific, unglamorous role: the thing an artist running a hybrid hardware-and-modular performance rig actually needs to route everything through live, which matters more to how often a piece of gear gets used than how much stage presence it has at a trade show. The mystery synth will get the demo videos; the NTS-4 is more likely to actually end up wired into someone’s live rig every week.
