KORG NTS-2 - Multifunction Oscilloscope Kit for Synthesizers (4 Channels, Dual Generator, FFT Analyzer and Tuner)

The KORG NTS-2 (Nu:Tekt) is a 4-channel handheld oscilloscope designed for electronic music and modular synthesis creators. In a pocket-sized, build-your-own form factor, it integrates an oscilloscope , spectrum/FFT analyzer , high-precision tuner , and a dual waveform generator with dedicated outputs . With dual stereo inputs (4 signals simultaneously) with CV and audio handling up to ±10 V and dual mono outputs (up to ±5 V), the NTS-2 is the ideal tool for calibrating VCOs, viewing LFOs and envelopes, verifying signal paths, or injecting auxiliary tones/LFOs into your system. Stereo THRU/OUT ports allow you to leave the NTS-2 hardwired on-set without interrupting your signal, even when powered off.

Its 2.8" RGB LCD display offers clear readability and dedicated modes for every task. The kit assembles without soldering and is powered by USB-C or 2 AAA batteries , for maximum flexibility in the studio and on stage. Compact, accurate, and easy to use, the NTS-2 brings reliable metering and essential utilities to any synth setup.

Main features

• 4-channel oscilloscope (two stereo inputs) with scales from 10 mV/div to 10 V/div , time from 50 µs/div to 1 s/div and Auto /rising/falling edge trigger.
• Dual shape generator with two independent mono outputs (up to ±5 V ): sine, square, triangle, saw, pulse (duty variable), noise , LFO and envelope, with phase/frequency adjustment.
• Spectrum/FFT analyzer (0 Hz–20 kHz) with channel selection and scale control.
• Precise tuner with “needle” and “VU” modes, adjustable reference A4=410–480 Hz , detection range approx. 20.60 Hz–6,272 Hz and accuracy of ±0.1 cent .
• Synthesis-focused connectivity : 2× stereo inputs (4 signals, ±10 V max), 2× stereo THRU/OUT ports for adding it to your chain, and 2× mono generator outputs (±5 V max).
• 2.8" RGB LCD display and direct controls for vertical, horizontal, trigger and input selection.
• Dual power supply : USB-C (5 V) or 2×AAA (≈ 2 h typ.).
• Compact DIY kit for easy assembly without soldering ; includes USB cable and assembly guides.

Product benefits

• Quick signal flow diagnostics : Simultaneously display up to four waveforms to compare modulations, phases, and levels.
• Precise calibration and tuning : Tune analog oscillators to fine tolerances (±0.1 cent) and verify filter/envelope responses.
• More creativity : Use the dual generator as auxiliary LFOs or test oscillators (up to ±5 V) to modulate or test patches.
• Seamless Integration : THRU/OUT ports allow the NTS-2 to be left wired without breaking the signal path, even when powered off.
• True portability : battery or USB-C, pocket-sized and lightweight chassis to take from the table to the live show.

Use cases

• Modular/semi-modular : check CV amplitudes (±10 V), polarities, clipping and phase shifts between LFOs/clock.
• Study : align levels between machines, inspect harmonic content with FFT, generate calibration tones.
• Training : Visualize in real time how filters, envelopes, and modulations affect the waveform.

Frequently Asked Questions

• Do I need to solder to assemble it? No. Assembly is quick and requires no soldering .
• Can I leave it connected all the time? Yes. Its THRU/OUT ports allow the signal to flow even when the NTS-2 is off.
• Can the outputs be used as LFOs/test tones? Yes. The dual generator delivers up to ±5 V per output with multiple shapes.
• What power supply does it support? USB-C 5V or 2x AAA batteries (typical battery life ≈ 2h).
