Synchronize a loop to its regular BPM but instead of the normal length, make the length double the original length (for example, if your normal length is 8 beats, then make it 16-beats). What you get is a really cool slowed down breaky thing. This works well with Drum ‘n Bass, Hiphop, Breakbeat, etc. Add a tiny bit of reverb on the slowed down loops to give them more volume too.
