**To make vocal harmonies in FL Studio, choose a second melody that fits the lead and the chords, then sing it as a new take or create it with Pitcher or NewTone. For Pitcher, route a clean single-note vocal through the plugin, match its MIDI port to MIDI Out, and enable MIDI, Octaves and Harmonize. Write the harmony notes in MIDI Out's Piano roll. For NewTone, move the detected notes individually and send the edited audio back to the Playlist.**

The plugin can change the pitch. It can't decide which line belongs in your song. I'd work out a short harmony phrase against the chords before building a whole stack; that gives the editing a musical target rather than a list of semitone offsets.

## Choose the harmony notes before choosing the plugin

A harmony is a different pitched part heard alongside the lead. Another take of the same melody is a double, and an unchanged copy is neither a newly sung double nor a new harmony. Decide whether you want a higher answer to the lead, a lower support line, or several chord voices. You don't need to fill every phrase.

If you meant harmonizing an instrument melody, start with the [chord-progression workflow](https://flstudiopro.com/fl-studio-chord-progression-tool/). The note choices still matter, but MIDI instrument notes don't need vocal pitch detection. This page deals with a sung line and the audio tools that can support it.

Start with a few important notes in the hook. Identify the chord underneath each one, then try another note from that chord above or below the lead. Chord tones are a manageable first approach, not a rule that every passing note must be a chord tone. The [basic construction of major and minor triads](https://www.musictheory.net/lessons/40?ref=flstudiopro.com) gives you the root, third and fifth to work with.

**Moving every note up the same number of semitones doesn't automatically produce a harmony that fits the key.** A third counts note names, while its exact distance can vary. As the [lesson on specific intervals](https://www.musictheory.net/lessons/31?ref=flstudiopro.com) explains, a major third spans four semitones and a minor third spans three. Those are different moves in a pitch editor.

| Chord and lead note | Example harmony | Move above lead |
| ------------------- | --------------- | --------------- |
| C major, lead C4    | E4              | 4 semitones     |
| D minor, lead D4    | F4              | 3 semitones     |
| E minor, lead E4    | G4              | 3 semitones     |

This is a teaching example in C major, with one chord under each lead note. The harmony follows the thirds of those three chords. Shifting the entire lead up four semitones would turn D4 into F-sharp4, which changes the intended D minor sound. The example isn't a preset for a different song.

![Harmony note choices in C major: C4 to E4 over C major, D4 to F4 over D minor, and E4 to G4 over E minor](https://storage.ghost.io/c/23/d1/23d1461e-9a6f-4583-9f0a-3ee044fc8192/content/images/2026/10/fl-studio-vocal-harmonies-notes.webp)

The same musical interval can require a different semitone move. Choose the note against the chord.

Try the phrase slowly on a keyboard or a simple instrument first. Keep the line in a range the singer can handle, and let it move smoothly where the arrangement allows. If a note clashes, change the note or its timing before reaching for EQ. A key label is useful, but the chord and melody at that moment give you a more specific decision.

## Pick a route that fits your source and licence

| Route                 | Good fit                                   | Main limitation                        |
| --------------------- | ------------------------------------------ | -------------------------------------- |
| Record another part   | A singer can perform the chosen line       | Needs a fresh take and alignment       |
| Pitcher plus MIDI Out | You want editable MIDI-controlled voices   | Needs clean monophonic input           |
| NewTone               | You want to shape each note in saved audio | Needs note editing and an audio export |

Image-Line [lists Pitcher and NewTone among the Signature Bundle plugins](https://support.image-line.com/action/knowledgebase?ans=39&ref=flstudiopro.com). Check that your licence includes the tool you intend to use. Merely finding a plugin in the picker isn't proof of a licence. Recording external audio inside FL Studio requires [Producer Edition or higher](https://www.image-line.com/fl-studio-learning/fl-studio-online-manual/html/recording%5Faudio.htm?ref=flstudiopro.com).

For a new performance, follow the [vocal-recording setup](https://flstudiopro.com/fl-studio-record-vocals/) and use the lead plus the chord progression as the singer's reference. If you already have a dry vocal file, either editor route can start from it when the required plugin is licensed.

Prepare a clearly pitched single vocal line. Don't feed a full song or a choir into Pitcher and expect it to identify one lead. Image-Line specifies [monophonic input and placement before chorus, phasing or reverb](https://www.image-line.com/fl-studio-learning/fl-studio-online-manual/html/plugins/Pitcher.htm?ref=flstudiopro.com) because those effects can interfere with detection. Leave the original lead available on its own route.

## Build a MIDI-controlled harmony with Pitcher

Pitcher is useful when you want to change the harmony's notes in a Piano roll instead of rendering a new file after every musical edit. It changes the pitch of the incoming vocal under MIDI control. The MIDI part supplies target notes; the vocal supplies the sung sound and phrasing.

1. **Give the harmony source its own Mixer insert.** Duplicate the vocal clip and use [Make unique](https://flstudiopro.com/fl-studio-make-unique/) to give the copy its own Audio Clip channel. Assign that channel to an insert named Harmony source. Keep the original lead on its separate insert. An ordinary Playlist lane doesn't establish the route by itself.
2. **Load Pitcher first on Harmony source.** Keep the input dry enough for pitch detection. Disable other tuning or widening effects while you establish this route.
3. **Enable MIDI in Pitcher.** The port display appears at the lower left. Choose an unused port number; 2 is just an example.
4. **Add MIDI Out to the Channel Rack.** Set its Port to the same number as Pitcher. This is a port match, not the Mixer insert number or the MIDI Channel field.
5. **Enable Octaves and Harmonize as well.** Image-Line's harmonizing setup calls for MIDI, Octaves and Harmonize when playing chord voices. Keep the source and MIDI pattern running together in Song mode.
6. **Open MIDI Out's Piano roll.** Write one chosen harmony note over each vocal event to begin with. Place that pattern beside the source audio in the Playlist. Once one voice follows correctly, add more simultaneous target notes if the arrangement needs them.
7. **Choose Replace for this separate harmony path.** It replaces the input on that path with the harmonized output. The original lead still supplies the dry performance on its own insert.

The [Pitcher MIDI setup](https://www.image-line.com/fl-studio-learning/fl-studio-online-manual/html/plugins/Pitcher.htm?ref=flstudiopro.com) documents the matching ports and mode switches. Its Harmonize mode accepts up to four MIDI notes, including their played octaves. Ordinary MIDI mode follows a target note within the detected octave; the modes don't all do the same job.

![Pitcher MIDI harmony setup with port 2 matching MIDI Out port 2, MIDI Octaves and Harmonize enabled, and Replace selected on a separate harmony route](https://storage.ghost.io/c/23/d1/23d1461e-9a6f-4583-9f0a-3ee044fc8192/content/images/2026/10/fl-studio-vocal-harmonies-pitcher.webp)

Match the two ports, then write the target pitches in MIDI Out. Port 2 is an example, not a required value.

Start the MIDI notes slightly before the corresponding vocal attacks. Image-Line recommends this so the target pitch is ready when the word begins. Don't move the entire audio recording early to compensate for late MIDI notes; adjust the control part.

Turn on **Formant** if you want Pitcher to preserve the vocal's formants while the pitch changes. That is a useful starting choice for recognizable backing vocals, although it doesn't guarantee that a large shift will sound natural. The [Pitcher controls guide](https://flstudiopro.com/fl-studio-pitcher/) covers detection, correction speed, Formant and Gender in more detail.

Use **Mix** when you deliberately want the plugin to combine incoming audio with harmonized voices on that insert. With a separate dry lead already playing, Mix introduces another copy of that input into the overall stack. That may be intentional, but it makes balancing less clear. I'd start with Replace on the separate harmony path.

[MIDI Out produces MIDI messages, not audio](https://www.image-line.com/fl-studio-learning/fl-studio-online-manual/html/plugins/MIDI%20Out.htm?ref=flstudiopro.com). A silent MIDI Out channel is normal. If the harmonies are silent too, check the incoming vocal, the matching ports, the active mode switches, and whether the MIDI pattern is actually playing at the same time as the audio.

## Make a note-by-note harmony in NewTone

NewTone suits a part that needs local pitch decisions. You can move a held note to a chord tone, change a passing note, or keep one phrase in a different register without sending every note through the same transposition.

1. **Keep the lead file untouched.** Open NewTone and load a copy of the vocal file through File > Load sample. The output will become a separate harmony file, not a replacement for the only lead recording.
2. **Inspect the detected notes.** Listen to the phrase and compare the blocks with the melody. If two sung notes have been detected as one block, use Cut to separate the event you need to move.
3. **Move each block to its target pitch.** Hold Ctrl and drag vertically through the note to select it, then click its target pitch on the Piano roll ruler to the left. The selected note snaps to that pitch. Work from the chosen harmony notes rather than dragging every block by an identical distance.
4. **Preserve the intended phrasing.** Leave the start and end of a word in place unless timing also needs repair. Global Center, Variation and Transition affect the file's correction behavior; they are not automatic harmony-composition controls.
5. **Send the result to the Playlist as audio.** Use Edit > Send to Playlist as audio clip, or the documented audio drag control. Label the new clip Harmony high or another meaningful role, and give it its own Mixer insert.
6. **Check it against the lead and chords.** Verify the first word, the last held note and the section boundaries. Keep the source and save the edited audio with the project.

These controls and the audio-return commands are documented in the [NewTone manual](https://www.image-line.com/fl-studio-learning/fl-studio-online-manual/html/plugins/Newtone.htm?ref=flstudiopro.com). Pay attention to the output: **Send to piano roll** sends detected notes as MIDI, while **Send to Playlist as audio clip** sends the vocal sound. A MIDI export isn't a rendered harmony vocal.

![NewTone note editing with separate targets E4 F4 and G4, plus the Edit menu command Send to Playlist as audio clip](https://storage.ghost.io/c/23/d1/23d1461e-9a6f-4583-9f0a-3ee044fc8192/content/images/2026/10/fl-studio-vocal-harmonies-newtone.webp)

Edit the notes that need a different pitch, then return audio to the Playlist. MIDI note export serves a different purpose.

If the part sounds thin or cartoonish after shifting, try a closer register or a different line. NewTone also exposes formant editing in Advanced Edit, but treat that as a sound decision after the pitches fit. For a deeper editing walkthrough, use the [NewTone guide](https://flstudiopro.com/fl-studio-newtone/). Don't keep stretching and shifting a poor source when a new sung take would solve the problem more directly.

## Record the harmony when performance matters

A pitch-shifted copy inherits the original delivery. If the backing line needs a different vowel shape, a softer consonant, a different breath or a sustained ending, record that part. The musical line can stay the same while its delivery makes room for the lead.

Let the singer hear the chosen lead and enough of the chords to hold the target notes. Record the harmony as a purposeful part, not as a spare lead take to be reassigned afterwards. Keep separate Playlist lanes and Mixer inserts for parts that need different levels or tone. The [Mixer routing guide](https://flstudiopro.com/fl-studio-mixer/) explains the underlying channel assignments.

Align word starts and phrase endings where a loose attack distracts from the lyric. Preserve useful movement between voices. A waveform match alone can't tell you that the harmony is musically right; listen to it with the chord changes, especially on long notes and section transitions.

## Balance the harmony around the lead

Set the lead in the song first, then bring up one harmony until its musical contribution is clear. If the backing line takes over the lyric, lower it or simplify where it appears. A harmony can earn its place on the final word of a phrase without running through the whole verse.

Pan only after the notes and levels work. Pitcher offers panning for its four voices and a Stereo Spread control; don't confuse a wider output with a better harmony. Separately recorded parts can use their own Mixer pan controls. Keep the lead easy to locate, and check that the backing parts still make sense in mono.

Use the [vocal-mixing workflow](https://flstudiopro.com/fl-studio-mixing-vocals/) for the broader EQ and dynamics chain. Reduce breaths or sibilants that build up across the stack with the [de-essing approach](https://flstudiopro.com/fl-studio-de-ess-vocals/) on the offending part. Shared [reverb and delay sends](https://flstudiopro.com/fl-studio-reverb-delay-sends/) can help the parts occupy the same space while their dry levels remain independently adjustable.

If you group the harmonies on a bus, check their direct Master routes. Adding a send doesn't automatically remove the source's existing path. The lead should remain independently controllable in this setup. Use the [stereo-separation guide](https://flstudiopro.com/fl-studio-stereo-separation/) for a temporary mono check, then restore the intended stereo setting before export.

## Fix the musical or routing problem you can identify

| Problem                                       | Check                           | Useful correction                             |
| --------------------------------------------- | ------------------------------- | --------------------------------------------- |
| The harmony clashes                           | Target note against the chord   | Change that note, not the whole file          |
| Pitcher ignores MIDI                          | Ports, modes and pattern timing | Match ports and play both parts together      |
| The first syllable starts at the wrong pitch  | Target-note start               | Place MIDI slightly before the vocal attack   |
| The lead becomes louder with the harmony path | Pitcher Mix and parallel routes | Separate the intended dry and harmony signals |
| NewTone returns no sung audio                 | MIDI export versus audio export | Use the Playlist audio command                |
| The voice sounds strained                     | Shift size and source delivery  | Try a closer line or record a new part        |

FLEX has a pack called Harmony, but that name describes [a playable vocal instrument built from samples](https://www.image-line.com/fl-studio-news/flex-harmony?ref=flstudiopro.com). It doesn't turn your lead recording into the specific backing line chosen above. Use it if that sampled texture is the goal; use the recorded, Pitcher or NewTone route for this task.

Before exporting, follow the harmony through the whole section with the chords playing. Confirm the intended notes, clear words, separate routing and saved audio. Keep the part only where it improves the arrangement.
