This bit breaks down the force settings that drive Vector Delay's particle simulation in Ableton Live, the physics engine behind its modulation system. At the center sits the Attractor, which pulls or pushes particles based on the Strength control, with each particle's Mass affecting how strongly it responds.
Particles also carry a charge, shown as blue for positive and yellow for negative, and the Attract setting decides whether the Attractor acts on both charges or just one. Magnetism adds another layer, controlling how oppositely charged particles pull toward or push away from each other.
Because Strength, Mass, Attract, and Magnetism all interact, tiny tweaks to any one of them can produce outsized, unpredictable shifts in how particles move, and in turn how your delay parameters get modulated. The practical takeaway is to nudge these controls gradually and watch how the whole system responds before committing to a setting.
