This quick walkthrough breaks down the two foundational controls in Ableton's Delay device. Dry/Wet sets the balance between your original signal and the delayed version, letting you decide how present the effect feels in the mix.
Feedback determines how much of the delayed output gets routed back into the device, which is what generates the repeating echoes people associate with delay. Live caps this parameter at 95%, giving you a wide range from a single subtle repeat to a dense, cascading trail without the signal spiraling out of control.
