Delay lock setting problem

hello, I wonder if anyone can help. I cannot get lock setting from the delay setup page to work as described in the manual. It says that if the feedback is set to 127 and the send value to 0, the delay buffer will be repeated infinitely. However I get no delays or repeats whatsoever with lock in the 1 position and FB at 127, and send at 0, only silence.
The manual doesn’t say that this depends upon anything else, so I don’t know what I’m doing wrong, any ideas anyone?

Many thanks…
