It has been mentioned before by a few people, so yes I would definitely Plus one this ableton link, need something to spice up my sets, as I am getting a bit board.
The only option to do anything special is looping on the deck layers, but that is quite awkward to do with any consistency and without being able to mark the tracks you want to use on the seconds deck layer so they are visible as this! when you put them in a playlist, it gets messy and often confusing especially if say you wanted to use a couple of looped tracks over your playing track, its just awkward and takes too much setting up. But with Ableton you can set a large or extensive loop collection or looped track sections as I like etc, so although it would mean using a laptop at present I really need this enjoyment factor, I like to spice things up a lot, so again I say ableton link would be exiting
And I doubt I could afford any decent sampler / or if Denon release a sampler, so ableton link is my best option +1 or plus 100
