Vector Delay in Ableton Live is a polyphonic delay built around a 2D particle simulation, and this walkthrough covers its layout before diving into the core delay controls. The particle display sits on the left, while the right side houses tabs for delay parameters and particle behavior, starting with the standard Time, Feedback, and multimode filter controls you'd expect from any delay.
Three controls set it apart from a conventional delay. Pitch re-pitches only the delayed signal, leaving your dry signal untouched, which opens up harmonized or detuned repeat effects without processing the source.
Recycle takes that re-pitching further by feeding the shifted repeats back into themselves, building a cascade of steadily rising (or falling) pitches with each repeat. Pair that with the option to play any repeat in reverse, and you get a delay that can generate melodic, evolving textures rather than just straight echo trails.
