Works in Max for Live. Otherwise largely useless in anything else. If you open it as a VST in Cubase or as an audio unit in Logic the scrolling function doesn't work - very annoying. A great idea but extremely awkward and clumsy in actual practice. Download the demo and see for yourself. If they ever release a bug free version, I might buy it. Also please note that once Liquid Rhythm is instantiated, Celemony Melodyne will not. Which company is to blame? I don't know but I need Melodyne more than Liquid Rhythm.
