Idea for tape loop simulation in Logic Pro

Make up a short section of music, say, 13 seconds. Copy, mix differently and chop to 11 seconds. Bounce then pull both back in to new project as separate tracks and loop. Will drift out of sync and re-sync at 13 x 11 secs at 2 mins 23 secs, so that's as much as needed.

version 1: kick, hats, odd guitar chord and synth sounds that throw up odd squalls
version 2: rhythmic moog synth sequence with a couple of atmospheric sounds on top
