Chopping means cutting a sample into pieces, or slices, and triggering them in a new order. Every DAW and sampler can do it. What separates a great chop from a messy one is where you cut and what you do next.
New to sampling in general? Start with how to sample soul music.
Where to cut
Cut on transients: the sharp start of a sound, like a piano chord landing or a snare hitting. A chop that starts right on a transient feels tight. One that starts a little late feels sloppy, however good the idea is.
Most tools can detect transients for you. Use it as a starting point, then move markers by hand where the detection gets it wrong.
How to avoid clicks
A click happens when a slice starts or ends in the middle of a waveform. Two fixes:
- Tiny fades. A few milliseconds of fade in and fade out on each chop removes clicks without softening the attack much.
- Zero crossings. Many editors can snap slice points to where the waveform crosses zero, which is naturally click-free.
How many chops?
Start with fewer, longer chops: one per chord or phrase. Long chops keep the musicality of the original, and you can always cut them smaller later. Chopping into 32 tiny pieces straight away usually gives you a pile of fragments and no idea.
Three chopping styles
Phrase chops
Slice by musical phrase, like a bar or a chord change, and rearrange the order. It's great for new progressions from soul chord changes.
Stabs
Take single hits (a chord, a horn stab, a vocal "hey") and play them rhythmically. Stabs turn a sample into an instrument.
Micro chops
Tiny slices played fast for stutters, rolls and glitchy textures. Use sparingly, for fills and transitions.
Play, don't just program
Map your chops to pads or keys and play them in real time. You'll find rhythms and orders you'd never draw on a grid, and they'll feel human. Record a few passes and keep the one that feels best, then tidy the timing.
Hide your tracks
Once you have a pattern:
- Pitch individual chops up or down to create new melodies from the same material.
- Reverse a chop for a lead-in or transition.
- Filter chops differently so the pattern has movement.
That's how a chopped sample becomes a new composition. More in how to flip a sample.
