To **arpeggiate in FL Studio**, write or record a chord in the Piano roll, select its notes, then press **Alt+A** on Windows or **Option+A** on macOS. The **Piano roll Arpeggiator** turns the chord into editable notes. If you want the chord to remain intact while FL Studio generates the arpeggio during playback, use the **Channel Settings arpeggiator** instead.

Those two routes sound similar, but they leave the project in different states. One prints the rhythm where you can move every note. The other stays **real-time** and reversible. Choose that boundary before touching speed, direction or octave range.

## Choose editable notes or a live arpeggio

| You need                                            | Start with                   | What remains after setup                  |
| --------------------------------------------------- | ---------------------------- | ----------------------------------------- |
| Notes you can delete, tie, move and vary            | Piano roll Arpeggiator       | Ordinary editable notes                   |
| A reversible effect while chords stay readable      | Channel Settings arpeggiator | Original chord notes plus live processing |
| A programmable event pattern inside a modular patch | VFX Sequencer in Patcher     | An event-routing system                   |
| A plugin’s own preset arp                           | The plugin arpeggiator       | Behavior depends on that plugin           |

The first two are the useful default choices. Patcher and plugin-specific sequencers can go much deeper, but they are poor starting points when the actual job is “make these three chord notes play one after another.”

The Piano Roll tool writes notes; the Channel arpeggiator processes source notes during playback.

## Prepare a chord the arpeggiator can read

Open an instrument’s Piano roll and place a chord long enough to cover your intended phrase. For a simple test, use C, E and G starting and ending together. Overlap matters when you want the live arpeggiator to read those notes as a held chord. The Piano roll score tool can also process individual notes: its preset determines the rhythm and pitch changes, so it is not limited to blocked chords.

Make the harmony work before adding motion. Play the blocked chords through the progression and listen to the bass. An arpeggiator can expose a wrong chord tone more clearly because it repeats that note on its own. It cannot repair harmony by moving quickly.

If you are still learning the Channel Rack, Pattern and Playlist relationship, build the first eight bars with the [beginner project workflow](https://flstudiopro.com/fl-studio-tutorial-beginners/) before adding a second note-generation system.

## Use the Piano roll Arpeggiator with Alt+A or Option+A

1. Open the Piano roll for the instrument that holds the chords.
2. Select the chord notes you want to transform. With nothing selected, the command may affect the wider score.
3. Press **Alt+A** on Windows or **Option+A** on macOS. You can also choose Tools > Arpeggiate from the Piano roll menu.
4. Load or confirm an **arpeggio pattern**, then preview the result while the dialog is open.
5. Set Time multiplication, range, direction and Gate in that order.
6. Choose Accept only after the final chord change and bar boundary still land correctly.

The [Image-Line Arpeggiator manual](https://www.image-line.com/fl-studio-learning/fl-studio-online-manual/html/pianoroll%5Farpeggiate.htm?ref=flstudiopro.com) describes this as a non-real-time tool. Accept writes the changed notes into the Piano roll; it does not leave an arp effect running. Use project History to undo an unwanted result, and duplicate the source Pattern before experimenting if you want to keep both versions. A duplicate Pattern preserves note data, not a separate copy of every Channel setting.

## Pick the pattern before changing every control

The selected **FL Studio Score (.fsc)** supplies the pattern used to transform the source notes. Use the folder button beside Pattern to load one. Start with a simple shape and inspect the generated notes. Do not assume every preset merely plays the existing chord tones: custom arp scores can transpose the source notes as well as change their rhythm.

Normal follows the score as written. Flip vertical reverses its vertical relationship. Alternate switches between the normal and flipped versions on successive repetitions. Audition those three before reaching for a more complicated preset.

A preset is a starting shape, not proof that the output fits your progression. Audition all four chords, not just the first one. If an unexpected pitch appears, inspect the selected score and the generated notes before changing the harmony. You can correct one printed note without abandoning the entire phrase.

## Set speed with Time multiplication

**Time multiplication** stretches or compresses the loaded score pattern. The official tool offers integer relationships: slower multiples in one direction and faster divisions in the other. Think in musical density rather than a magic knob position.

For a simple repeating three-note order at sixteenth-note spacing, the cycle has three events while a quarter-note beat contains four sixteenths. Its accent therefore rotates against the beat unless something restarts the cycle. That can be useful movement. Check the final generated note before every chord change rather than assuming one knob position guarantees a complete cycle.

Do not use the arpeggiator to repair a performance that was simply recorded off the grid. That timing-correction task belongs to the [quantize workflow](https://flstudiopro.com/fl-studio-quantize/); the arp tool is creating an order and rhythm that did not exist in the blocked chord.

## Check Sync when the pattern stops or restarts unexpectedly

The Piano roll tool’s **Sync** option decides what marks the end of its loop; it is not an audio-driver or MIDI-clock setting. In the [documented Sync modes](https://www.image-line.com/fl-studio-learning/fl-studio-online-manual/html/pianoroll%5Farpeggiate.htm?ref=flstudiopro.com), **Time** disables repetitions, **Block** treats all notes turning off as the loop boundary, and **Chord** uses one chord note turning off.

If an arp does not repeat across a held chord, check Sync before repeatedly turning Time multiplication. If it restarts early, inspect unequal source-note endings. Keep the test chord’s notes the same length, compare Block and Chord, then choose the behavior that fits the phrase.

## Keep octave range under control

Range controls the octave span of the generated movement. Start with one octave for a restrained bass, pluck or accompaniment, then audition a wider span if the phrase needs it. This is a musical starting point, not a rule that every instrument sounds best within one octave. The preset and range pattern also shape the final pitches.

Check the highest and lowest generated note against the patch. A short pluck may sound clean across three octaves; a sampled instrument may reveal awkward stretching, and a bass can leave the frequency range that supports the song. “More range” is not “more musical.”

Keep the two Pattern controls separate. The score Pattern mode changes its normal/flipped behavior; the **Range pattern** decides the octave traversal. Normal repeats low to high, Flip repeats high to low, and Alternate goes low–high–high–low. Listen at the turnarounds instead of assuming an unexpected accent is off-grid timing.

## Use Gate for articulation, not tempo

**Gate** shortens the generated note lengths. Lower values create detached, staccato pulses and leave room for delay or reverb. Longer values connect notes and can create legato when the instrument supports it. Gate does not change how often new notes start; Time controls that rhythmic spacing.

Listen to the synth envelope. A long release can make the sound from short MIDI notes overlap even though the note events do not. A slow attack may hide much of a fast phrase. Adjust the patch’s articulation and note lengths together; do not reach for heavy compression just because the individual pulses are hard to hear.

![Piano roll arpeggiator Pattern, Time multiplication, Range, Gate and Levels controls](https://storage.ghost.io/c/23/d1/23d1461e-9a6f-4583-9f0a-3ee044fc8192/content/images/2026/08/arp-controls.webp)

Load the score at the top, then adjust its behavior; check Sync separately when repetition does not match the phrase.

## Add velocity and pan movement after the notes work

The Piano roll tool’s Levels controls mix the source score’s per-note properties with those in the loaded pattern. Turning a control right brings in more of that pattern’s corresponding property. Velocity, pan and pitch changes are useful only if the instrument responds to them; third-party plugins do not necessarily support every [FL Studio per-note property](https://www.image-line.com/fl-studio-learning/fl-studio-online-manual/html/pianoroll.htm?ref=flstudiopro.com). Test a small change before building a phrase around it.

For a human pulse, make one or two notes in the cycle quieter, then change the emphasis at a phrase boundary. For deliberate stereo motion, keep the bass centered and move higher notes modestly. If the pattern needs a larger repeating parameter change, the [automation guide](https://flstudiopro.com/fl-studio-automation/) gives that movement a visible arrangement-level lane.

## Use Channel Settings for a live, reversible arp

Open the instrument’s detailed settings and select the Miscellaneous, or wrench, page. In its **Arpeggiator** section, choose Up for a straightforward test. The [Channel Settings manual](https://www.image-line.com/fl-studio-learning/fl-studio-online-manual/html/chansettings%5Fmisc.htm?ref=flstudiopro.com) lists Off, Up, Down, Up-Down, a second Up-Down that repeats the highest and lowest notes, and Random. Use Off to stop the Channel arp without deleting the source notes.

Right-click the arp’s **Time** knob and choose **Set** for its timing presets, then adjust the arp Gate for note length. Do not confuse these with the separate **Time** section on the same settings page, which has its own note-truncation Gate. Start with a simple patch, one-octave Range and a held chord so you can hear each change clearly.

Choose **Auto** when the live arpeggiator should use the chords in the Channel’s note data. **Auto (sustain)** has an important exception: with Range set to 1, it leaves monophonic sequences unarpeggiated. If a single held note does not pulse, check that combination before treating it as a fault.

**None** is different: it moves in 12-semitone octave steps within the selected range. The other Chord presets impose predefined chord structures rather than arpeggiating the incoming chords in the same way as Auto. If the output no longer resembles your harmony, check this selector first.

Slide requires an instrument that supports FL Studio’s slide behavior; the Channel slide/portamento mechanism does not work with VST/AU instruments. A plugin may have its own glide controls, but those are a separate feature. Repeat works with Range: it determines how many times a note or arpeggio chord repeats before moving to another octave. Change one setting and replay the same two chords.

## Commit the live arpeggio when you need editable notes

A live arp is quick to audition, but one generated note is hard to edit until you capture it. In the Channel Rack, **right-click the instrument’s Channel button > Burn MIDI to > New pattern**. The [Burn MIDI instructions](https://www.image-line.com/fl-studio-learning/fl-studio-online-manual/html/channelrack.htm?ref=flstudiopro.com) also offer Current pattern, which writes back into the current Pattern. Prefer a separate result when preserving the blocked chords matters.

Put the driving notes in that Channel’s Piano roll first. Burn MIDI is not simply a recorder of whatever you happen to play live on a keyboard; without input notes, you may receive the message that the selected channel has no notes to burn. For native Channel arpeggiation, FL Studio presents a prompt to disable Arpeggiator and Echo afterward. Accept the appropriate disable action so the captured notes are not processed twice.

Keep the original source Pattern named and out of the active arrangement while you audition the printed version. Do not mute their shared instrument Channel just to silence the source Pattern—that can also silence the result. Disabling the Channel arp affects other Patterns that use that Channel, too. If another section still needs live processing, preserve a separate project version or give that section its own cloned instrument Channel and check its settings before continuing.

Now edit the printed phrase: remove a doubled turnaround, lengthen one passing note, or leave a rest before the next section. Compare the sound before and after capture rather than assuming the first burn is correct.

If you are using [FL Studio Trial](https://www.image-line.com/fl-studio-learning/fl-studio-online-manual/html/app%5Ffeature.htm?ref=flstudiopro.com), you can save a project but cannot reopen it until purchase. Render needed audio before closing the session. If a licensed host warns about unowned trial plugins, unlock them before reopening; do not overwrite the original after reopening with their states missing.

For a VST/AU arp, two things must be true: the plugin must output its generated MIDI, and its Wrapper must have a MIDI Output port selected. That port need not be routed anywhere for Burn MIDI to see the output. Image-Line cautions that many instrument plugins do not expose their internal arp notes at all; hearing an arp is not proof of MIDI output support.

Inside Patcher, the note-generating module also needs a green Events connection to **To FL Studio** with a MIDI port selected. An audio cable alone cannot expose those notes. The [Patcher routing guide](https://flstudiopro.com/fl-studio-patcher/) covers the difference between event and audio paths. If MIDI output is unavailable, use a native note-generation route or record audio when you only need the sound—not editable note events.

## Choose a live route for changing the arp during playback

The Alt/Option+A dialog is an editing tool, not a persistent plugin. After Accept, there is no running Piano roll arp whose Time multiplication knob can sweep through the arrangement. Edit the generated notes for deliberate variations, or use the Channel arp or a suitable Patcher/plugin setup when the generating rule must remain live. Check the chosen control’s actual automation support instead of assuming every arp parameter can be linked.

## Turn a loop into a four-bar musical phrase

An arpeggio becomes tiring when every bar answers the same way. Keep the harmony readable, then change only one decision per phrase. The wider [Pattern-loop arrangement workflow](https://flstudiopro.com/fl-studio-loop-patterns/) explains when to share a stable Pattern and when to make only the variation unique.

- Bar one establishes the basic order.
- Bar two changes one velocity accent.
- Bar three raises or removes one note near the end.
- Bar four leaves a rest or shortens the final cycle before the next section.

Those edits create direction without hiding the chord progression. The [Piano roll shortcut reference](https://flstudiopro.com/fl-studio-shortcuts/) speeds up selection, duplication and note movement once the live result has been printed.

![Four-bar note phrase with changing pitch contour, velocity accents and a closing gap](https://storage.ghost.io/c/23/d1/23d1461e-9a6f-4583-9f0a-3ee044fc8192/content/images/2026/08/arp-variation.webp)

Compare the contour, accents and space before the loop restarts. The shown phrase is not a fixed chord progression to copy.

## Know when Patcher is the better next step

Use the two basic routes until you need a programmable step pattern, note filtering or scale handling that stays live. [VFX Sequencer](https://www.image-line.com/fl-studio-learning/fl-studio-online-manual/html/plugins/VFX%20Sequencer.htm?ref=flstudiopro.com) in Patcher takes incoming notes or chords and sends its generated sequence to a connected instrument. Route the input into the sequencer and its note output into the instrument; add the separate host event-output connection described above only when capturing those notes with Burn MIDI.

Do not move to Patcher because a four-note loop feels repetitive. Print the simple arp and edit the phrase first. A modular graph is valuable when the rule itself must stay live, not when ordinary Piano roll notes would be clearer.

## Run this arpeggio quality check

- The blocked chord progression sounds correct before processing.
- The chosen tool matches the need for editable notes or a live effect.
- The pattern completes or turns around intentionally at chord changes.
- Time multiplication creates the intended density.
- The octave range stays inside the instrument’s useful register.
- Gate and the synth envelope produce clear articulation.
- Velocity or pan movement supports the pulse without masking weak notes.
- A burned Pattern does not pass through the live arp a second time.
- The fourth bar creates a reason to hear the first bar again.

Continue through the [FL Studio Workflow hub](https://flstudiopro.com/tag/workflow/) when the note pattern works. The next useful move is usually arrangement, automation or editing, rather than another random arp preset.

## Frequently asked questions

### What is the shortcut to arpeggiate in FL Studio?

Open the instrument’s Piano roll, select the chord notes and press Alt+A on Windows or Option+A on macOS. This opens the Piano roll Arpeggiator and writes editable notes when you accept the result.

### Why is the FL Studio arpeggiator playing only one note?

Check which tool you are using. In the Channel arp, confirm Auto rather than None or an unintended chord template, and that your chord notes overlap. Auto (sustain) with Range 1 leaves a monophonic sequence unarpeggiated. In the Piano roll tool, inspect the selected score pattern and Sync mode; a preset may repeat one pitch or stop rather than loop.

### Can I turn the Channel Settings arpeggiator into Piano roll notes?

Yes. Add source notes to the instrument’s Piano roll, then right-click its Channel Rack button and choose Burn MIDI to > New pattern. Disable the live arp when prompted and audition the result. Third-party plugins must expose generated MIDI and have a Wrapper MIDI Output port selected; many internal plugin arps do not expose it.

### What is the difference between Gate and arpeggiator speed?

Speed controls when generated notes begin; Gate shortens their duration. The instrument’s envelope also affects what you hear: a long release can make separate MIDI notes sound connected. Change note length and patch articulation separately when checking a smeared rhythm.

### Should I use the Piano roll or Channel Settings arpeggiator?

Use the Piano roll tool when you want visible, editable note events. Use Channel Settings when you want to audition a live reversible effect while keeping the source chords intact.
