Arch Linux

This section describes the installation on Arch Linux.

Prerequisites

PMX-1 is a Linux application written in C++. It use systemd, pipewire and wireplumber, and depends on GRPC, Protobuf, and other libraries. For development and debugging tools, it also depends on fish.

It uses meson and g++ for compilation.

The mixer uses several LV2 plugins for signal processing.

Installing dependencies on Arch Linux

To install (nearly) all dependencies in one shot, use the following command:

sudo pacman -S systemd pipewire wireplumber boost grpc protobuf yaml-cpp \
    libsystemd dbus fish git meson pipewire-audio pipewire-jack calf jalv \
    dpf-plugins-lv2 tmux cmake

Afterwards, we need to install two dependencies from the AUR.

Installing replxx

PMX-1 also uses replxx, which only has an AUR package so far. To install that, either uses the AUR helper of your choice, or clone the repository and build the package as follows:

git clone https://aur.archlinux.org/replxx.git
cd replxx
makepkg
sudo pacman -U replxx-*.pkg.tar.zst

Installing open-stage-control

git clone https://aur.archlinux.org/open-stage-control-bin.git
cd open-stage-control-bin
makepkg
sudo pacman -U open-stage-control-bin-*.pkg.tar.zst

Installation

PMX-1 is implemented in multiple repositories, which ultimately culminate in three installations: the PMX-1 back-end services, the Admin UI to configure routing, and the Open Stage Control GUI.

Installing the back-end services

The back-end services are implemented as a collection of interconnected custom pipewire filters, filter chains, osc and grpc services and wireplumber scripts, all orchestrated and managed as systemd units and configured via pipewire metadata.

To install all of that using the AUR package, execute the following commands:

git clone https://github.com/performance-mixer/pmx-git-arch
cd pmx-git-arch
makepkg
sudo pacman -U pmx-*.pkg.tar.zst

Installing the Admin UI

The PMX-1 Admin UI is an ASP.net application. It uses the GRPC API to communicate with the mixer and can be run everywhere, in this section, we will show how to build and install the application, the setup will be described in the Setup section.

Running straight from the repository

The easiest way to run the Admin UI is to clone the repository and run it straight from the project directory.

git clone https://github.com/performance-mixer/pmx-grpc
git clone https://github.com/performance-mixer/pmx-admin-ui
cd pmx-admin-ui/Pmx.Admin.Ui/
dotnet run

This will start the application and print the URL it listens on. Open it in the browser and the Admin UI is ready.

Installing system-wide

Installing the GUI

The Open Stage Control GUI is distributes as and Open Stage Control Interface, which can be opened and edited in Open Stage Control exactly like any other interface. To get the latest delivered version, clone the git repository.

git clone https://github.com/performance-mixer/pmx-osc-ui

To start the GUI, open pmx_osc_ui.json in Open Stage Control.
