Contact your local dealer! This offer is available worldwide! Buy a StudioLive CS18AI before April 31, and you'll get Studio One Professional along with it. There's no better controller for Studio One, because nobody knows Studio One like we do. But it doesn't just control Studio One. You can also enjoy touch-sensitive moving fader control of the StudioLive RM Rack mixers via a simple Cat5e or Cat6 Ethernet cable, and sell that clunky old analog snake.
