Just got a Numark Mixtrack running through Mixxx, an open-source DJ program, and with a Behringer mixer thrown in the mix, I am ready for my gig!

Mixxx is great, though I wish it could detect key signatures… oh well.

Mix installs straight from apt-get or pacman, but on rpm-based distros you’ll need to compile from source (not a big deal)

(Arch users, be sure to get the kernel module: sudo modprobe snd_seq_midi)

There’s no need to pay for thousand dollar software just to blare some tunes, just use Mixxx!
