Updated
Linux Distribution, as well as tools and packages for other Debian/Ubuntu based distributions via PPA, geared towards professional audio recording and production. Some of it's packages have also been ported to Fedora/CentOS/RHEL, or to the AUR on for access on distros like Arch Linux, Chakra Linux, or Manjaro, and even MacOS X and Windows, though the source code is obviously open licensed and available on SourceForge and github. The official KX Studio distribution tends to favor Qt toolkits and packages, as well as LXQt and KDE/Plasma desktop integration, as the maintainer, Philip, who goes by the online handle FalkTX, prefers them, though they work just fine on Enlightenment or GTK based desktops like Moksha, Cinnamon, XFCE, or GNOME. FalkTX also had a role in mainstream windows VST Wine bridging on Linux via the Festige library he created, and is active in the Ardour, Reaper, and Mixbus Linux communities. He has expressed interest in the next ISO for KX Studio being based off of Netrunner or KDE Neon, as opposed to Kubuntu LTS releases, as it has been in the past.

Pros
Pro Devs contribute to upstream and support the community
I have personally seen posts by FalkTX on the user forums and social media groups for open and closed source software like Reaper, Ardour, Mixbus, and a few other things I can't recall off the top of my head. I have also seen him in mailing lists and in publicly disclosed bug report threads for multiple distributions, and the Linux Kernel itself. The words "Bastion" and "Pillar" come to mind.
Pro Not technically JUST a distribution
Many of the custom tools, scripts, plugins, and software made by FalkTX for KX Studio are available in other distributions or even on other operating systems, and their features make them indispensable for recording or gigging musicians. The PPA's can be added into any Debian or Ubuntu based distro, meaning everything from Peppermint to Linux Mint to Pardus to Deepin to Bodhi supports it. Some of the packages and scripts have Debian or Ubuntu specific optimization flags. This is the ONLY pro I can find for this, and the only one needed to justify it's usage.
