No, it won't do that I'm afraid. As the clock varies within a certain
tolerance, the echoplex will stay in sync by retriggering the loop to keep
it lined up. But if the tempo changes too much, it assumes that you don't
want to stay in sync anymore and it stops trying. So then the loop just
plays on in its normal length. The echoplex can't do time stretching or
tape-speed-changing effects. Still very useful though, because most clocks
have a lot of jitter and drift around in speed. The sync keep things lined
up, so that the loop and the sequencer or whatever don't drift from each
other.
