## Base setup

 * Install Debian stable
 * Add kxstudio repos (see http://kxstudio.linuxaudio.org/Repositories): ` wget https://launchpad.net/~kxstudio-debian/+archive/kxstudio/+files/kxstudio-repos_9.0.0~kxstudio1_all.deb, sudo dpkg -i kxstudio-repos_9.0.0~kxstudio1_all.deb`
 * switch CPU Frequency scaling to Performance
 * realtimeconfigquickscan
