Ableton's Vector Delay runs on a 2D particle simulation, and this walkthrough shows how each particle attribute can drive a different delay parameter. A particle's horizontal position controls Pan, and since Vector Delay is polyphonic, the Voices setting spins up multiple particles, each acting as its own independent delay line with settings shaped by where that particle sits in the display.
Vertical position maps to Pitch, with a Scale setting that quantizes the re-pitched output to specific intervals, like locking modulation to 7 semitones instead of a free glide. Distance from center controls Time, so delay length shifts based on how far each particle drifts from the middle of the field.
Speed maps to Gain, tying loudness to how fast a particle moves, and Mass, visualized as particle size, maps to Feedback. Together these five mappings turn a swarm of moving particles into a living, multi-voice delay where motion itself becomes the modulation source.
