Chopping a loop into pieces you can replay in any order is one of the most creative moves in sample-based production. To slice samples in FL Studio, the two main tools are Slicex (for slicing and replaying via the Piano Roll) and Edison (for detailed editing). This guide shows how to slice a loop at its transients and rearrange it into something new.
Quick way: drag a loop into Slicex
The fastest method is to drag an audio loop from the FL Studio browser straight onto the Channel Rack while holding the option to open it in Slicex (or add a Slicex channel and load the sample into it). Slicex automatically detects transients and creates a slice marker at each hit.
- Open Slicex and load your loop.
- Check the slice markers — Slicex places them at detected transients. Use its slicing/sensitivity options to add or remove markers until each drum hit gets its own slice.
- Each slice is now mapped to a key, so opening the Piano Roll lets you trigger slices in any order.
Rearranging slices in the Piano Roll
Open the Slicex channel’s Piano Roll. Each note triggers a different slice, lowest notes usually playing the earliest slices. From here you can:
- Replay slices in a new order to create a fresh groove.
- Stretch or shorten how long each slice plays.
- Repeat a single slice for stutter and roll effects.

Dumping slices to the Channel Rack
Slicex can also send each slice to its own channel via its dump slices option. This is handy when you want to treat each chop as a separate drum sound — process them individually, swap sounds, or trigger them step by step. From there you can sequence them in the step sequencer like any drum kit, and the same chops are a quick way to build the foundation of a beat from a sampled break.
Editing with Edison
When you want surgical control, use Edison, FL Studio’s built-in audio editor. Add it to a mixer track’s effect slot or open it from a sampler channel, then:
- Highlight a region and trim, normalise, or reverse it.
- Use its region/slice tools to mark cut points by hand.
- Drag an edited selection straight back into the Channel Rack or Playlist.
Edison is also where you clean up clicks and silence at the start of a sample before slicing, which keeps your chops tight.
Choosing the right slicing method
The tool you reach for depends on what you want the chops to do. Knowing which approach fits the job saves you redoing work later.
- Replaying a loop melodically or rhythmically: stay in Slicex and use the Piano Roll. This keeps everything in one channel and is the quickest route to a new groove from an existing loop.
- Building a custom drum kit from a break: use Slicex to slice, then dump the slices to the Channel Rack so each hit becomes its own channel you can mix, layer and process independently.
- One-shot or vocal chops that need cleaning: start in Edison, trim the silence and tidy the transient, then send the polished selection out to a sampler channel.
There is no single correct workflow — many producers combine all three, prepping in Edison, slicing in Slicex, and dumping to the Channel Rack only when a chop earns its own processing chain.
Cleaner chops: a few practical tips
Most sloppy-sounding slices come down to where the cut lands and how the slice ends, not the tool itself. A handful of habits make a big difference:
- Cut just before the transient. If a marker sits slightly late you’ll clip the attack of the hit and lose its punch. Nudge the marker a hair earlier so the full transient is captured.
- Watch for clicks at slice boundaries. A chop that cuts off mid-waveform can pop. A short fade-out on each slice, or zero-crossing edits in Edison, smooths these over.
- Mind the tails. Slices with long reverb or cymbal tails can overlap and muddy the groove when replayed quickly. Trim or fade the tail if it bleeds into the next hit.
- Keep a clean source. Heavily compressed or already-mastered loops are harder to slice cleanly because the transients are squashed together. Drier, more dynamic source material slices far more accurately.
Keep your slices in time
Slicing works best when the loop’s tempo matches your project tempo, otherwise slices may drift. Set your project BPM to the loop’s tempo, or use Slicex’s time-handling options so slices play back at the right speed. When you need to fit a loop to a different tempo without re-chopping it, our guide on how to time-stretch audio in a DAW walks through the trade-offs. Tight timing here keeps the rest of your mix grooving.

Frequently asked questions
What’s the difference between Slicex and Edison for slicing?
Slicex automatically detects transients and maps slices to the Piano Roll so you can replay them as a kit. Edison is a full audio editor for precise manual editing, cleanup and trimming. Many producers use Edison to prep a sample, then Slicex to chop and replay it.
How do I slice a loop at every drum hit?
Load the loop into Slicex and let it auto-detect transients, then adjust the slicing sensitivity until each drum hit gets its own marker. You can add or remove slice markers manually if the detection misses a hit.
Why are my slices out of time?
Usually the loop’s original tempo doesn’t match your project tempo. Set your project BPM to the loop’s tempo or use Slicex’s time-stretch options so the slices play back in sync.
Can I slice samples without Slicex or Edison?
Yes. You can manually chop a sample on the Playlist with the slice tool, or load it into a basic sampler channel and set the start and end points by hand. Slicex and Edison simply make transient detection and detailed editing much faster, especially on busy drum loops.
