01
CAB Simulation
Added CAB simulation and TONE adjustment.
Firmware V2.2.1 introduces CAB Simulation, allowing Loop Core Stereo to deliver a more authentic speaker cabinet sound across playback, monitoring, and recording scenarios.
An independent TONE control has also been added, enabling quick adjustment of the overall tonal balance and output character, so your loops sound more natural and closer to a real performance.
02
USB Audio + Loopback
Added USB Audio function with Loopback recording.
USB Audio has been added, allowing Loop Core Stereo to integrate seamlessly into computer-based audio workflows for recording, loop import/export, and everyday music creation.
Loopback Recording has been added, allowing computer playback audio and the device’s audio signal to be combined into a single recording stream—ideal for livestreaming, tutorial recording, backing track capture, and content creation.
03
MIDI Clock + PC Control
MIDI Clock Sync & MIDI PC# to switch memory 01~99.
Firmware V2.2.1 adds MIDI CLOCK sync mode, enabling Loop Core Stereo to stay in perfect tempo alignment with external MIDI devices for live performance and multi-device setups.
The “IGNORE START & STOP” switch supports manual or automatic LOOP start and stop.
MIDI Program Change (PC#1–PC#99) allows direct switching of Memory 01–99.

The NUX Loop Core Stereo is our next generation Looper pedal. Featuring a high-definition color LCD display, stereo inputs/outputs, and a MIDI control input; the Loop Core Stereo allows you to create up to 6 hours of music phrases, save them in one of 99 provided memory slots, and play back as stereo loops! Also included are 50 different drum patterns to complete the looping experience. Whether you practice, compose, or play live gigs, you’ll be inspired from the very first loop!
Create and save your loops
It’s easy to create loops and practice with the NUX Loop Core Stereo.
Power on the Loop Core Stereo pedal, rotate the VALUE knob to select an empty memory from 01 ~ 99, then you can press the foot switch to record/play/dub your loops. You can also hold the foot switch to UNDO/REDO/CLEAR.
Turn the VALUE knob to select a memory slot between 01~99 or adjust parameters.
When you are working on loops or practicing, press the VALUE knob once/twice to adjust the volume of Loop/Drum.

4 example setups with the Loop Core Stereo.
Setup 1
Mono in, mono out.
This is the most common loop pedal setup for guitarists. Plug in a guitar to the A/Mono input on the Loop Core Stereo and connect A/Mono output directly to a guitar amplifier. And finally, set the AUDIO PATH as shown below.
Setup 2
Stereo in, stereo out.
Set the AUDIO PATH as shown below.
Setup 3
OUT A for guitar, OUT B for drum machine.
To get the best sounds, you can connect the Loop Core Stereo to a guitar amplifier and a full-range frequency amplifier.
Set the AUDIO PATH as shown below. This will split the guitar signal and drum machine signal to OUT A & OUT B individually.
Setup 4
Both OUT A & B to a mixer.
When you are playing at home or in the studio with a mixer and/or PA system, you can connect the Loop Core Stereo to control the mix of your guitar and drum machine individually. Additionally, this setup includes a frequency compensation function to get a better signal from OUT A.
Set the AUDIO PATH as shown below.
MIDI Control
Nearly every parameter of the Loop Core Stereo can be controlled by an external MIDI controller, such as tap tempo, stop/start/record, and so much more. The MIDI to 1/8” cable is included to get you started quickly.
*Please download the user’s manual and check the MIDI commands.
Customize your own Boot-up picture
The Loop Core Stereo allows users to customize their own boot-up picture with a GIF.

How to import playback to Loop Core Stereo?
When connecting a LOOP CORE STEREO to a computer, it will show “NUX LOOPER” as a USB flash disk. Click it, and you will see folder NCL-2. Click folder NCL-2 to enter, then you will see folder WAVE. Then you can drag the target wav file into the related folder. For example, if you want to put the playback wav file into phrase loop track 3, you can just drag your target wav file into folder W003. Then you are good to go.
Note: LOOP CORE STEREO only supports 44.1kHz/32 bits Stereo floating WAV format, please download and utilize NuxFormatConverter to convert your backing track to the correct file format. Please go to the Softwares section on this page for download.
(Please use NuxFormatConverter to convert your playback to the correct format.)
