First. You can se delay max to 99ms which is kinda low for sound delay processors. Professional cheaper hardware units can do about 135-150 ms. Very expensive like Eventide BD600+ can do up to 80 seconds and including functions like: segments, panic and dump.
DAW do not reacts to delay change immediately. You can change to maximum and it delay will be still at initial zero value for tens of seconds. Also in Opposite direction. This makes plugin quite unpredictable and not recommended for use.
