Hi,
My advice would be to figure out what you really want and need and go in one direction. There is totally no sense in wanting to use both a tablet software and controller and ALL major DJ Software for computers.
When I look at what you are writing I think you’d be better off spending all that time learning all those software and preparing your tracks for each software by working on your collection instead and by mastering one piece of gear.
Unlike traditional gear, you are not dependent on what you’ll find at clubs/venues. You bring your own controller and software of choice. So there is no reason to become familiar with all DJ software and have it all operational, imho.
DJ Player, althouh fabulous software, has a steep learning curve. It pays to invest time in it, but ONLY if you plan on making it your primary (or only) platform for DJ-ing.
Some controllers that work well with tablets are just under-featured for more serious DJ-ing than full-featured computer-only controllers. I don’t see much chance of getting that 1 controller that has it all.
