Korg Nu:Tekt NTS-2 Multifunction Oscilloscope Kit

The Korg Nu:Tekt NTS-2 Oscilloscope Kit is a compact multifunction utility designed for synthesizer enthusiasts, modular users, electronic musicians, and sound designers who want professional signal analysis in a portable format. Combining a 4-channel oscilloscope, FFT spectrum analyzer, precision tuner, and dual waveform generator, the NTS-2 is an indispensable tool for visualizing, testing, and creating audio and control voltage (CV) signals.

As part of Korg's innovative Nu:Tekt DIY series, the NTS-2 is supplied as an easy-to-build kit that requires no soldering. Assembly takes only a short time, allowing users to enjoy both the building experience and a professional-grade utility that enhances any synthesizer, Eurorack, semi-modular, or desktop music production setup.

4-Channel Oscilloscope for Audio and CV Analysis

The NTS-2 features a high-resolution 4-channel oscilloscope designed specifically for musicians rather than laboratory use. It allows you to monitor multiple audio or CV signals simultaneously, making it easy to understand modulation, envelopes, oscillators, filters, LFOs, and complete signal paths.

Multiple display modes include single-channel, stereo, four-channel, and XY (Lissajous) visualization, providing valuable insight into waveform behavior and phase relationships.

• View up to four signals simultaneously
• Real-time waveform visualizationIdeal for audio and control voltage monitoring
• Perfect for modular and semi-modular synthesizers

Integrated FFT Spectrum Analyzer

The built-in Fast Fourier Transform (FFT) spectrum analyzer provides real-time frequency analysis, allowing musicians to examine harmonics, overtones, filter response, resonance, and overall tonal balance. This visual feedback is invaluable for sound design, synthesis education, and troubleshooting complex signal chains.

Dual Waveform Generator

Beyond signal analysis, the NTS-2 includes two independent waveform generators capable of producing multiple signal types for testing and creative modulation.

• Sine
• Square
• Triangle
• Sawtooth
• Noise
• Pulse
• Envelope

The generators operate in both audio-rate and control-voltage applications, making the NTS-2 useful as an additional modulation source within a modular synthesizer system.

High-Precision Built-In Tuner

Korg incorporates its renowned tuning technology into the NTS-2, offering highly accurate pitch detection for synthesizers, guitars, basses, and other electronic instruments. Both needle and meter display modes provide fast, intuitive tuning during studio sessions and live performances.

Portable DIY Design

The Nu:Tekt NTS-2 arrives as a DIY kit that requires no soldering, making assembly quick and accessible for users of all experience levels. Its compact size allows it to fit comfortably into a backpack, gig bag, or studio workspace while remaining powerful enough for professional applications.

The unit operates from either USB-C power or two AAA batteries, giving musicians complete flexibility whether working in the studio or performing on location.

Bright Full-Color Display

A vibrant 2.8-inch RGB LCD provides excellent visibility for waveform analysis, frequency displays, tuner readings, and function generator settings. The intuitive interface enables quick navigation through measurement modes and system parameters.

Ideal for Modular and Desktop Synthesizers

The NTS-2 has been designed to integrate seamlessly with Eurorack systems, desktop synthesizers, drum machines, sequencers, and semi-modular instruments. Its voltage ranges and audio connectivity make it an invaluable diagnostic and creative tool for modern electronic music production.
