Live 4 can do pretty much anything any other sequencer can do and in half the time. I've used Cubase, Acid, Fruity etc and produce quicker and better tracks than I have ever done with any of those. All dance music is loop based and Live can record loops or if you want linear recordings and can be used to make as complex a track as you are capable of. My advice is get it, there is no better software on the market that provides the same ease of use.
