TL;DR: Expert Sleepers has announced two new Eurorack modules heading to Superbooth: the NTX-8CV, a 4 HP Swiss Army knife that acts as USB MIDI-to-CV converter, 8-channel DC-coupled audio interface, and disting NT expander; and Forever, a dedicated freeze/sustain effect derived from the disting NT’s Temporal Freeze algorithm, offering three independent freeze voices with overdub capability. The NTX-8CV is priced at $219 and slated for summer 2026, while Forever lands in Q3 2026 with pricing still under wraps.
- NTX-8CV packs three functions into 4 HP: USB MIDI-to-CV (8 outputs), DC-coupled audio interface (8 outputs), and expander for disting NT (daisy-chainable to 64 CV outputs).
- Forever is a dedicated freeze/sustain module with three independent voices, manual or CV triggering, and overdub functionality — all in a single Eurorack module.
- NTX-8CV is class-compliant USB host, meaning you can plug a MIDI controller directly in without a computer.
- NTX-8CV priced at $219 / £179 / €172.25, available summer 2026; Forever price TBA, arriving Q3 2026.
- Both modules include USB ports for MIDI control, configuration, and firmware updates.

The 4HP Multitool: NTX-8CV
Expert Sleepers has long been the quiet workhorse of the Eurorack world, known for modules that make your modular system talk to your computer without drama. The NTX-8CV is the latest addition to that lineage, and at 4 HP, it’s the most compact ES module to offer eight CV outputs. Let that sink in: four horsepower, eight control voltages. That’s efficiency that would make a Swiss watchmaker blush.
The module wears three hats. First, it’s a USB MIDI-to-CV converter. Plug a class-compliant MIDI controller directly into the USB port — no computer required — and you get up to eight control voltages out. Second, it’s a DC-coupled audio interface with eight outputs. This means you can send control voltages from your DAW (Ableton Live, Bitwig, or Expert Sleepers’ own Silent Way) straight into your modular. Third, it doubles as an expander for the disting NT, adding eight CV outputs to that module. And if eight isn’t enough, you can daisy-chain multiple NTX-8CV units for up to 64 CV outputs. Because sometimes you need to modulate everything, including the modulator’s modulator.
Pricing is set at a refreshingly reasonable $219. That’s less than many single-function 4 HP modules. Expert Sleepers knows that in a world of overpriced boutique modules, sometimes you just want clean, functional utility. Summer 2026 is the target, which gives you time to save your pennies and rearrange your rack.
Forever: The Freeze Machine
The second announcement, Forever, is a different beast entirely. It’s a freeze and sustain effect lifted directly from the disting NT’s Temporal Freeze algorithm — but now it gets its own dedicated module. For those unfamiliar, a freeze effect captures a slice of audio and holds it indefinitely, like a photograph of sound. Forever adds three independent freeze voices, each with its own trigger input and the ability to overdub new material on top of the frozen buffer.
This is the kind of module that rewards experimentation. Want to build a drone from three different audio sources? Layer a vocal snippet over a field recording over a synth pad? Forever lets you do that, with manual or CV control over each voice. The USB port handles MIDI control, configuration, and firmware updates. It’s essentially a disting NT feature given its own dedicated space, which is a smart move by Expert Sleepers: take a popular algorithm, strip away the menu diving, and give it physical controls.
Forever is due in Q3 2026. Pricing hasn’t been announced, but knowing Expert Sleepers, it won’t break the bank. We’ll update you as soon as we know more — probably over a cup of something strong.
Specs and Practicalities
Let’s talk numbers. NTX-8CV: 4 HP, eight DC-coupled outputs, USB host functionality, class-compliant (no driver installation on most systems), expandable to 64 CV outputs via daisy-chaining. It runs on standard Eurorack power (+12V / -12V). Forever: audio I/O, three trigger inputs, USB port for MIDI and updates. No word on power draw yet, but we’d be surprised if it’s a hog.
Both modules feel like they were designed by someone who actually uses Eurorack. The NTX-8CV’s ability to function as a USB host means you can plug a keyboard or controller directly into your rack without a computer acting as middleman. That’s a workflow win for live performance and studio jams alike. Forever’s overdub capability is a creative tool that could easily become a staple in ambient, drone, and experimental setups.
One small caveat: the NTX-8CV’s audio interface function is DC-coupled, which is essential for sending CV from a DAW. If you’re using it purely for audio, make sure your system can handle DC — most modern interfaces can, but it’s worth checking. Otherwise, you might get some unexpected modulation where you wanted clean audio.
Market Context: Who Needs This?
Expert Sleepers occupies a unique niche in the Eurorack ecosystem. They’re not flashy, they don’t have blinking lights or Instagram-friendly front panels. What they do have is rock-solid utility that bridges the gap between modular and computer-based workflows. The NTX-8CV is for anyone who wants to integrate their DAW with their modular system without dedicating half their rack to interface modules. It’s for the person who owns a disting NT and wants more CV outputs. It’s for the live performer who needs to control their rack from a keyboard without a computer.
Forever is for the drone enthusiast, the ambient artist, the person who spends hours layering textures. It’s for anyone who’s ever wished their freeze effect had more than one voice. It’s not a replacement for a dedicated sampler or looper — it’s a focused tool for a specific sound.
At Noxal, we appreciate when a company understands its strengths. Expert Sleepers isn’t trying to be Make Noise or Mutable Instruments. They’re the utility belt of Eurorack, and these two modules are classic additions to that belt. The NTX-8CV, in particular, feels like a no-brainer for anyone with a disting NT or a DAW-centric workflow.
Frequently Asked Questions
Can I use the NTX-8CV as a standalone MIDI-to-CV converter without a computer?
Yes. The NTX-8CV is a USB host and class-compliant, so you can connect a MIDI controller directly via USB and it will output up to eight control voltages. No computer required.
How does Forever’s overdub feature work?
You can record additional audio on top of the existing frozen buffer. Each of the three voices can be triggered independently, and you can layer new sounds over the frozen material. It’s like building a sonic collage in real time.
Can I daisy-chain multiple NTX-8CV modules?
Yes, you can daisy-chain several units for up to 64 CV outputs. This makes it scalable for larger systems or complex modulation needs.
We’ll be at Superbooth with a fresh pour-over and a notebook, trying to get hands-on with both modules. If you see us, feel free to interrupt — just bring coffee.
