NAMix

NAMix is a neural amp modeller plugin for Linux. It is based on NeuralAmpModelerPlugin by Steven Atkinson and all contributors to the Neural Amp Modeler project. All original copyright is retained by Steven Atkinson.

iPlug2, the framework used by the original plugin, does not currently support Linux. NAMix is a Linux port built using JUCE. Because JUCE is used, this project is released under the GNU General Public Licence v3. See LICENCE and NOTICE for full details.

NAMix ships as two separate binaries:

Binary	Use
NAMix.vst3	VST3 plugin — load inside a DAW (REAPER, Ardour, Bitwig, Carla, …)
NAMix (standalone)	Standalone application — runs without a DAW, connects directly to your audio interface

---

System requirements

NAMix requires glibc 2.35 or later. This is present in:

Distro	Version
Ubuntu	22.04 LTS or newer
Debian	12 (Bookworm) or newer
Devuan	5 (Daedalus) or newer
Fedora	36 or newer
Linux Mint	21 or newer
Pop!_OS	22.04 or newer
MX Linux	23 or newer
Arch Linux	rolling
Manjaro	rolling
openSUSE Tumbleweed	rolling
Void	rolling

Ubuntu 20.04, Debian 11 (Bullseye), RHEL/CentOS 9, and openSUSE Leap 15.x ship glibc 2.31–2.34 and will not load these binaries. Users on those systems should build from source (see below).

Installing the pre-built release

Download NAMix-0.4.0-linux-x86_64.tar.gz from the Releases page.

Extract the archive:

tar -xzf NAMix-0.4.0-linux-x86_64.tar.gz

This creates a NAMix-0.4.0/ directory containing both binaries. Install whichever you need:

VST3 plugin — copy into your user VST3 folder:

mkdir -p ~/.vst3
cp -r NAMix-0.4.0/NAMix.vst3 ~/.vst3/

The plugin will appear as NAMix in any VST3-capable DAW. No other dependencies need to be installed.

Standalone application — run directly from the extracted directory:

./NAMix-0.4.0/NAMix

On first launch, NAMix open audio settings dialog where you select your ALSA or JACK device and sample rate. These settings are saved and restored on subsequent launches. The standalone window includes a File → Preferences menu to reopen the audio settings at any time.

The standalone saves its last state (loaded model, IR, and all knob positions) automatically when you close the window.

To uninstall:

rm -rf ~/.vst3/NAMix.vst3 ~/NAMix-0.4.0

Building from source

git clone https://github.com/rations/namix-linux.git
cd namix-linux
git submodule update --init --recursive

cmake -B build -DCMAKE_BUILD_TYPE=Release
cmake --build build --parallel $(nproc)

Required system packages (Debian/Ubuntu):

build-essential cmake pkg-config libx11-dev libxext-dev libxcursor-dev
libgl-dev libfreetype-dev libfontconfig-dev libpng-dev zlib1g-dev
libcurl4-openssl-dev

After building, install the VST3:

mkdir -p ~/.vst3
cp -r build/NAMixLinux_artefacts/Release/VST3/NAMix.vst3 ~/.vst3/

Or run the standalone directly:

build/NAMixLinux_artefacts/Release/Standalone/NAMix

To build and package a release archive (produces NAMix-0.3.0-linux-x86_64.tar.gz in the repo root):

bash scripts/makedist-linux.sh

Usage

1. Load a .nam model file using the folder icon on the NAM row.
2. Optionally load an impulse response (.wav) on the IR row.
3. Adjust Input, Output, and tone-stack knobs (Bass, Mid, Treble) to taste.
4. The EQ toggle enables or disables the tone stack.
5. The Noise Gate toggle enables the noise gate; the Threshold knob sets the gate level.
6. The ⚙ (gear) button opens the settings panel where you can configure the input calibration level and output mode (Raw / Normalized / Calibrated).
7. If the loaded model supports slimming, a small icon appears to the right of the NAM row. Click it to open the Slim overlay and reduce the model size.
