Mixxx 2.0.0

What's new in this version:

Dynamic, Resizable Skins:
- Each of our three professionally-designed skins can stretch to fill whatever size screen you have. Turn parts of the interface on and off to reveal the features you use most.

4 Decks with Master Sync:
- Supporting the latest DJing techniques, Mixxx supports up to four decks playing back simultaneously. Combine tracks with loops and samples to create sophisticated on-the-fly remixes.
- Holding your mix together is the new Master Sync engine, a powerful feature that holds all of your tracks perfectly aligned even if you change the speed of the mix.

Harmonic Mixing with Musical Key Detection:
- Mixxx now detects the musical key of your tracks and allows you to fine tune them to be in key with the rest of your mix. With support for Traditional, Open Key, Lancelot, and custom key notations, you'll feel right at home no matter what system you're used to.

RGB Waveforms:
- See the sound of your music. With RGB waveforms, bright red means killer bass, blue glints where you find crisp hihats, and soft greens show you when the lyrics come in. A quick glance at the waveform overview and you'll know if a track is banging or just right for sunrise.
- Four Microphones, Four AUX Inputs, Microphone Ducking:
- Radio DJs, MCs, and users with external gear will appreciate the flexibility of 12 total external audio inputs. And with auto-ducking, listeners will always be able to hear you over the music.

Vinyl Passthrough:
