Reply to elusive effects assistance

is there any way to duplicate some of the effects that Hawtin, Carola and Dubfire use in their sets with just traktror&S4?

most specifically the freeze/delay they use that traps a sound and freezes it without dropping out everything else? If anyone needs i can probably find a vid link with that being used. I have been told the only way to do this is with running Ableton also, but was hoping to not need an additional laptop/controller/etc

also if adding an X1 will help(or the new native controller/software coming this summer) that's an option.
