Skins
Make QUP look the way your show feels. Every skin below dresses the whole engine (transports, faders, knobs, meters, the spectrum analyser and the DJ decks), and each one comes with its own colour ramps for the VU meters and analyser.
To get one: in QUP, open Plugins → General → Plugin Browser, find the skin and click Install, then pick it under Preferences → Display → Skin & Layout. A new choice takes effect the next time QUP starts. Skins are free: two come built in, and the rest download in a second, no restart needed to install. Want to make your own? See the skinning guide.
