A transition where the outgoing track decays into echoes as the next track begins.
An echo out is a transition move where a long delay or reverb effect is applied to the outgoing track at a phrase boundary, allowing its echoes to ring out and fade while the incoming track enters underneath. The result dissolves the outgoing track rather than cutting or blending it away.
Why it matters
It creates a sense of space and atmosphere at a transition point, working especially well at breakdowns or when moving between tracks with different energies. It is harder to misuse than a cut because the echoes mask the exact moment the outgoing track disappears.
In practice
Trigger the echo on the last downbeat of the phrase, match the delay time to the track BPM, then bring in the new track as the repeats decay. Many mixers have a dedicated beat FX button for this.
