The Sample Chopper lets you slice audio into pieces that you can trigger, rearrange, and play like an instrument. It's perfect for chopping loops, vocals, and creating sample-based beats.
Opening the Sample Chopper
-
Select a clip on the timeline
Click on the audio clip you want to chop. -
Open the Chopper
Click the scissors icon or right-click and select "Open in Chopper". -
The waveform appears
You'll see your sample displayed with chop points.
Chopping Modes
Transient Detection
Automatically detects hits and creates slices:
- Best for drums and percussive sounds
- Finds natural attack points in the audio
- Adjust sensitivity for more or fewer slices
Beat Division
Divides the sample evenly by beats:
- 1/4 — Quarter note slices
- 1/8 — Eighth note slices
- 1/16 — Sixteenth note slices
- 1/32 — Thirty-second note slices
Manual Slicing
Place chop points exactly where you want:
- Click on the waveform to add a slice point
- Drag slice points to adjust position
- Double-click a point to remove it
Working with Slices
Playing Slices
- Click a slice — Plays that slice once
- Use keyboard — Keys trigger slices (like pads)
- MIDI controller — Map slices to pads or keys
Rearranging Slices
- Drag slices — Move them to different positions
- Copy slices — Cmd/Ctrl+drag to duplicate
- Delete slices — Select and press Delete
Slice Parameters
Each slice can have individual settings:
- Volume — Adjust loudness of the slice
- Pitch — Shift pitch up or down
- Pan — Position in stereo field
- Reverse — Play the slice backwards
Tip: Chopping a sample and playing slices in a different order is a classic sampling technique. Try reversing some slices or changing their pitch for creative effects.
Common Chopping Workflows
Chopping a Drum Loop
- Load a drum loop into the Chopper
- Use transient detection to find the hits
- Adjust slices to capture each drum hit cleanly
- Assign slices to pads in the Drum Machine
- Create your own patterns from the chopped drums
Chopping Vocals
- Load a vocal sample into the Chopper
- Use manual slicing for precise control
- Cut between words or syllables
- Rearrange to create new phrases
- Add pitch variation for melody
Chopping a Melody
- Load a melodic sample (piano, synth, etc.)
- Slice on beat divisions or manually on notes
- Rearrange slices to create new melodies
- Pitch-shift slices to change the key
- Layer with other instruments
Slice Effects
Apply effects to individual slices:
- Stutter — Repeat the slice rapidly
- Fade In/Out — Smooth the start or end
- Stretch — Change length without changing pitch
- Reverse — Play backwards
Exporting Slices
Save your slices for use elsewhere:
- To Timeline — Drag slices directly to tracks
- To Drum Machine — Assign to pads
- To Library — Save as individual samples

Keyboard Shortcuts
| Click waveform | Add slice point |
| Double-click point | Remove slice point |
| Drag point | Move slice boundary |
| Space | Play/stop preview |
| 1-9, 0 | Trigger slices 1-10 |
| R | Reverse selected slice |
Tips for Clean Chops
- Zero crossings — Cut where the waveform crosses zero to avoid clicks
- Add tiny fades — A 5-10ms fade prevents pops
- Listen in context — Preview slices with your beat playing
- Less is more — Sometimes fewer, longer slices work better
