Stupid effects question.

Just watching some of the old tech tools tutorials and im just wondering:

What is the echo effect?? is it the delay??

And the freeze effect?? whats this??

Please and thanks:)

echo is a non synchronized delay

freeze samples a delay until you "unfreeze it", feedback determines the decay time

freeze is a function of the advanced echo effect.

all under the 'delay' .. but as it echo's it is referred to as echo alot too .. look into the adv settings for FX
