CHOPPING

Slicing a longer sample into pieces and reassigning them to pads or keys so you can replay the source in a new order. The core MPC technique.

Gear, instruments and tools — Top-down photograph of an Akai MPC Live standalone sampler showing its sixteen velocity-sensitive pads, touchscreen browser and Q-Link knobs — the hardware sampler workflow these gear terms describe.

Key takeaways

Slicing a longer sample into pieces and reassigning them to pads or keys so you can replay the source in a new order.
The core MPC technique.
Done on transients, it turns a four-bar loop into a playable instrument; done on non-transient points, it produces the stuttered, half-swallowed phrasing that defines a lot of sample-based production.
Slice on transients first, then delete every other slice and play the gaps yourself — you get a new groove out of the same four bars.
Watch out: chopping without setting the sample's tempo.

CHOPPING IN DEPTH

Chopping means cutting a longer sample into slices and assigning them to pads or keys so the source can be replayed in a new order. Done on transients, it turns a four-bar loop into a playable instrument; done on non-transient points, it produces the stuttered, half-swallowed phrasing that defines a lot of sample-based production.

How it works in practice

Slice on transients first, then delete every other slice and play the gaps yourself — you get a new groove out of the same four bars.

The mistake people make

Chopping without setting the sample's tempo. Once the slices drift against the grid, quantising them fixes timing but destroys the original feel.
