FL Studio 
To split a Pattern by channel in FL Studio, select the Pattern, open the Pattern menu and choose Split by channel. FL Studio creates one new Pattern for every active Channel in the selected Pattern and names each new Pattern after its Channel. Put those Pattern Clips in the Playlist, then mute or remove the original combined clip so the same notes do not play twice.
This command earns its keep when a drum loop, chord stack or instrument idea was written inside one Pattern and the arrangement now needs separate control. It changes the Pattern structure only. It won't render audio, create stems or reassign anything in the Mixer.
What Split by channel changes
A Pattern can hold note data for several Channels in the Channel Rack. You might have kick, snare, hi-hat and percussion steps inside one Pattern, or several instruments with Piano Roll notes under the same Pattern number.
Image-Line's Pattern menu documentation states that Split by channel creates a Pattern for each active Channel and names the new Patterns after those Channels. An active Channel is one that contributes data to the selected Pattern, so empty Channels don't get their own Pattern.
The result changes organization, not sound. The notes and steps get separated into Patterns you can select individually, while their Channel settings, instruments and existing routing stay attached to the same Channels.
How to split the selected Pattern
Pick the Pattern that holds the combined parts, either with the Pattern selector in the main toolbar or from the Picker Panel. Make sure it's the right Pattern before you run the command, because splitting the wrong one just gives you a pile of Patterns you didn't need.
Open the Pattern menu from the main toolbar and choose Split by channel. It happens instantly, and no dialog asks which Channels to include.
FL Studio adds the new Patterns to the project and uses the Channel names to identify them, so clear Channel names matter here. “Kick,” “Snare,” “Hi Hat” and “Bass” are easy to work with in the Picker Panel, while a row of generic plugin names is much harder to arrange. If the names are unclear, rename the Channels before splitting or rename the new Patterns afterward.
Find the new Patterns in the Picker Panel
Open the Playlist and look at the Picker Panel. The combined material now shows up as separate Pattern entries. Select each Pattern and place its Pattern Clip wherever that part should play.
The new Patterns are independent building blocks for the arrangement. You can let the kick run through a breakdown, drop the hi-hat for two bars, bring the bass in later or write a fill without duplicating the whole combined groove. That's the main reason to split a dense drum Pattern once the idea moves from loop writing to song structure.
Keep Pattern names and clip colors consistent. The Playlist gets much easier to scan when the Picker Panel name, clip color and track label all tell the same story.
Remove the original clip or you may hear everything twice
The most common mistake happens right after the split: the original combined Pattern Clip stays active while the newly separated clips sit over the same bars. The kick in the original and the kick in the new Kick Pattern then fire together, and the same can happen to every other Channel.
If the result suddenly sounds louder, denser or phasey, check the Playlist before you touch the Mixer. Mute the original combined clip or remove it from the section. Then solo the separated clips one at a time and make sure each part plays only once.
You can keep the original Pattern in the Picker Panel as a temporary backup without placing its clip in the arrangement. Once the separated version checks out, give the original a clear name or move it out of the working section so it doesn't sneak back in by accident.
Playlist tracks are not Mixer tracks
Putting the Kick Pattern Clip on Playlist Track 1 doesn't route the kick to Mixer Insert 1. Playlist tracks organize Clips across time, and Mixer tracks process and route audio. Some workflows link the two systems, but their numbers don't automatically match.
Split by channel doesn't change the Mixer assignment of any Channel. A snare routed to Mixer Insert 7 before the split stays there afterward. If you need different effects, levels or buses, make those choices in the Mixer or the Channel settings, not by dragging the Pattern Clip up or down in the Playlist.
That's also why the command is safe for arrangement work: it separates sequencer data and leaves instruments and signal routing where they were.
Check Event Automation after splitting
Patterns can contain more than notes and steps. Image-Line's Pattern Clip documentation says Patterns may contain notes and Event Automation. The Event Editor documentation also explains that Event Automation is bound to a specific Pattern.
After splitting, check any parameter that was controlled through Pattern Event Automation. Play each new Pattern on its own and see where the events ended up. Automation Clips are separate Playlist objects, so don't confuse them with automation stored inside a Pattern.
If a parameter stops behaving as expected, open the Event Editor for that control and Pattern. Move or recreate the events only after you've worked out which Pattern should own them. Copying automation blindly into every new Pattern can cause repeated resets or conflicting values.
How to merge the separated Patterns again
The reverse workflow starts in the Playlist. Align the Pattern Clips so their starts and lengths represent the combined section, select the intended clips, then use Playlist menu → Edit → Merge selected clips. Image-Line lists this as the way to merge Pattern Clips after a split.
Selection matters. If an unrelated Pattern Clip is selected, it can end up in the merged result. Work on a short duplicate of the section when the arrangement is complex, and check the resulting Pattern before you replace anything.
Manual copying is the safer route when you only want part of one Pattern. Open the source Channel's Piano Roll, copy the notes you want, switch to the destination Pattern and paste them into the same Channel. For step-sequencer data, confirm the target Pattern length and timing before removing the source clip.
Split by channel is not stem export or audio separation
| Workflow | Result | Use it when |
|---|---|---|
| Split by channel | Separate Patterns containing sequencer data | You want independent Pattern Clips for arrangement |
| Merge selected clips | One Pattern built from selected aligned Pattern Clips | You want to recombine sequencer parts |
| Consolidate Playlist track | Rendered Audio Clip | You want a fixed audio version of a Playlist section |
| Split mixer tracks during export | Rendered audio stems | You need separate files for mixing or delivery |
| Stem separation | Estimated vocal, drum, bass or instrument audio layers | You need parts extracted from an existing audio file |
If you're delivering to another engineer, use stem export instead of Pattern splitting. If you want to pull drums or vocals out of a finished file, use stem separation. If you simply want to turn one Pattern into kick, snare, hat and bass clips you can arrange separately, Split by channel is the right command.
A clean workflow from loop to arrangement
- Rename the active Channels so the resulting Patterns will be clear.
- Select the combined Pattern and confirm it contains the intended parts.
- Open the Pattern menu and choose Split by channel.
- Find the new named Patterns in the Picker Panel.
- Place the new Pattern Clips on clearly labeled Playlist tracks.
- Mute or remove the original combined Pattern Clip from the same bars.
- Confirm that Mixer routing still points to the intended inserts.
- Inspect Pattern Event Automation and play each new Pattern independently.
- Use Merge selected clips only when you need to recombine aligned parts.
The command itself takes seconds. How good the result is depends on what happens around it: clear Channel names, one copy of each part in the Playlist, the right Pattern owning each automation, and a firm line between arrangement and routing. Get those four details right and a dense loop turns into a flexible song structure without rebuilding a single note.
