This Ableton tutorial demonstrates how to use Live's Gate with a sidechain input from the kick drum so the bass only plays when the kick hits, creating a tight, locked relationship between the two elements. It's a clean alternative to sidechain compression when you want rhythmic gating rather than ducking.
The Gate opens only when the kick drum signal crosses the Threshold, which you set by pulling it down until the bass responds to the kick. Attack, Hold, and Release then let you fine-tune the timing, controlling how quickly the gate opens, how long it stays open, and how fast it closes after each hit.
