Hey Guys,
The crossfade parameter allows the Digital Delay to change delay time
without either clicking or changing the pitch. This comes into effect
whenever you change the delay time, including via the knob, via the
expression pedal or aux switch, or via modulation. Specifically it has a
very profound effect on the modulation, allowing you to get slight
pitch change at very low settings, to something like flanging at medium
settings to some much more similar to a natural doubling at high
settings. In general it tends to give a more natural chorus sound than
pitch change type delays which can tend to sound very wet, especially
with feedback.
