Definition

A velocity layer is one of several distinct samples assigned to the same pad, each triggered within a specific range of how hard the pad is struck.

Example

A well-sampled snare might have a soft brushed sample for light hits, a medium sample for normal strokes, and a loud, cracking sample for hard hits. Tap the pad gently and you hear the first; dig in and you hear the third. The change is in tone, not just volume.

Why it matters

Real drums change timbre as well as loudness when hit harder, so simply turning a single sample up and down sounds fake. Velocity layers reproduce that timbral shift, which is what makes ghost notes and accents feel like one instrument played dynamically rather than two unrelated sounds stacked together.

How to play or configure

In a sampler or drum rack, load several captures of the same drum and assign each to a velocity window, for example 1–42, 43–95, and 96–127. Make sure the windows meet without gaps so every strike finds a layer. Then practise playing the pad across its full velocity range so you can summon any layer on demand. Round-robin samples can be stacked inside each layer for extra realism.
