You can use the looper as a 16 sec (and longer!!) delay.  Set a) max time to 16 seconds, b) play mode to ‘auto play’, c) dub mode to latch (if you want ‘feedback’) or repl-latch (if you don’t want feedback), d) decay at 100  (= ‘0% feedback’ in latch mode).

Record.  Playback will auto-start once you hit 16 seconds.

Start overdub and leave it running.  Your loop acts like a ’16 second delay’.

Adjust decay (in latch mode) to taste (0 decay = 100% feedback, 100 decay = 0% feedback).
