4DJ is DJ software with the layout DJs already know: decks, mixer, effects and browser where you expect them. It goes further with stems made on your own computer, transitions that stay in key and in tempo, a tablet as a second screen, and controllers that map themselves.
BEFORE YOU START (one time only) After installing, open a terminal and type these two commands, then open 4DJ again:
sudo snap connect 4dj-mixer:alsa
sudo snap connect 4dj-mixer:raw-usb
The Snap Store does not connect them for you yet: without them 4DJ still plays music, but your sound card and console may not show up.
Consoles driven over HID (such as the Kontrol S2 MK3) also need a udev rule once: when you plug one in, 4DJ shows the command to copy into the terminal.

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
On Arch Linux, snap can be installed from the Arch User Repository (AUR). The manual build process is the Arch-supported install method for AUR packages, and you’ll need the prerequisites installed before you can install any AUR package. You can then install snap with the following:
git clone https://aur.archlinux.org/snapd.git
cd snapd
makepkg -si
Once installed, the systemd unit that manages the main snap communication socket needs to be enabled:
sudo systemctl enable --now snapd.socket
If AppArmor is enabled in your system, enable the service which loads AppArmor profiles for snaps:
sudo systemctl enable --now snapd.apparmor.service
To enable classic snap support, enter the following to create a symbolic link between /var/lib/snapd/snap and /snap:
sudo ln -s /var/lib/snapd/snap /snap
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install 4DJ, simply use the following command:
sudo snap install 4dj-mixer
Browse and find snaps from the convenience of your desktop using the snap store snap.
