Music Remixer
Five musical groups. One clear intention.
Make room for dialogue while keeping the identity of the music. Understand the five Music Remixer groups, compare their levels and Mute states, then check transitions, rhythm and residual sounds in the finished scene.

Start with a problem inside the music
Music Remixer is a DaVinci Resolve Studio tool powered by the DaVinci Neural Engine. It separates finished music into five groups whose levels can be changed. It is useful when the composition fits the scene but part of its arrangement competes with speech or the intended emotional emphasis.
First compare a simple reduction of the whole music track. If that solves the problem while retaining the required energy, separation may be unnecessary. Remixer is particularly useful when you want to keep the rhythm and bass while lowering a competing vocal, or make one section of the scene feel less busy.
Treat the result as a processed version of the original mix. Five controls do not give you the original recording session with every microphone, instrument and effect on a separate track.
Dialogue over a song
Reduce the vocal group and judge whether the words become easier to follow while the music remains recognisable.
A change in scene energy
Compare the contribution of drums, bass and guitar. A small adjustment to one group may provide the needed emphasis.
An instrumental version
Mute the vocal group to evaluate an alternative. Check residual vocals, tails and changes to other instruments.

Find Music Remixer and establish its scope
Open the Fairlight Mixer and locate the music track. Enable Track FX in the three-dot Mixer menu; if Music Remixer is hidden, select it in Visible Track FX. These processors occupy fixed dedicated positions, and their controls are also accessible from the selected audio track’s Inspector.
Check the track name in the processor window. A track-level change applies to the musical clips on that track. If a neighbouring cue needs a different balance, decide whether another track or parameter automation will make the project easier to manage.
Compare by enabling and disabling Music Remixer itself. The channel’s Effects In switch controls inserts in the Effects section and does not bypass Track FX. Confirm that the intended processor is actually being compared before judging the separation.
| Element | Practical meaning |
|---|---|
| Track FX / Visible Track FX | Expose the dedicated Music Remixer control in the channel. Ordinary Effects inserts do not show whether Track FX is visible. |
| Music Remixer On / Off | Bypass the entire processor to compare with the original mix at the same passage. |
| Five level controls | Change the balance of the separated musical groups; 0 dB is the group’s unchanged level setting. |
| Mute below each group | Exclude that group from the result. Overall bypass returns the original music, so it is a different comparison. |
| Output | Observe changes in output level. Judge separation quality and speech intelligibility by listening. |

Five groups and their actual controls
The Resolve 21 manual names Vocals, Drums, Bass, Guitar and Other. Its interface illustration labels the first control Voice: this is the vocal group, not an additional sixth source. Other contains the remaining musical material.
The illustrated controls each show a −100 to +10 dB scale and an individual Mute button. Begin at 0 dB and change one group at a time. These numbers describe group gain, not the percentage of an instrument successfully separated.
| Group | What to try | What to protect |
|---|---|---|
| Voice / Vocals | Lower or mute a sung vocal that distracts from the presenter. | Vocal endings, reverb and instruments with overlapping harmonic content. |
| Drums | Calm the rhythm under an explanation or restore it at a scene change. | Attack definition, rhythmic stability and cymbals across transitions. |
| Bass | Change the low musical weight relative to speech and effects. | Musical body and the sense of a low rhythmic pulse. |
| Guitar | Reduce or feature guitar material that changes the scene’s density. | String attacks, sustained chords and neighbouring harmonic layers. |
| Other | Rebalance the remaining arrangement outside the four named groups. | The musical bed, melody and spatial tails. Other is not a single instrument. |

A first pass for music under narration
Prepare the comparison
In a duplicate timeline, choose 20–40 seconds containing a line entry, several words, a pause and music after the speech. Name the dialogue and music tracks and preserve the starting state.
Establish the overall balance
Make speech and music suitable for comparison with ordinary level adjustments first. If the words are already hard to follow without music, address the dialogue before changing the arrangement.
Test one group
Start with all groups at 0 dB and all Mute buttons off, then reduce the suspected source of interference. For example, compare the vocal group at 0, −3 and −6 dB. These are teaching comparison points, not a finished preset.
Compare Mute with attenuation
Listen to the stronger change, then return to a moderate level. Choose by intelligibility and musical continuity, including passages without speech.
Check neighbouring groups
Listen for changed attacks, low end or musical tails. Compare the original and processed versions at similar listening loudness.
Record the decision
Write down the changed group, the reason and the passage. If the scene needs movement, move on to automation after accepting the static balance.

Four purposeful uses of the remix
An interview over a recognisable song
Compare a lower vocal group first: the interview should remain easy to follow while the musical identity survives. If the whole bed still competes, test track level or Ducker.
An explanation before a faster montage
Try less drum energy during the explanation and restore the original balance at the edit. Listen with the picture and across the musical phrase.
A short instrumental bed
Mute the vocal group for evaluation, then check residual syllables and tails throughout the passage. If artifacts are distracting, compare an official instrumental version or another cue.
A less dense arrangement
Try Guitar or Other when the music’s midrange competes with speech. Other includes varied material, so recheck every section where instrumentation changes.
06 / UNDERSTAND & APPLY
Explore the balance of five groups
Change the musical group levels and their Mute states in the teaching model. Compare the arrangement when the vocal is reduced, the drums return or several groups are raised together.
The example uses predefined components. Its graph does not perform neural separation, play your file or measure Music Remixer quality. Take an idea into Resolve and record what you actually hear there.
Five components. Five separate decisions.
Lower the vocal without changing the drum control, or mute one component while keeping its chosen gain. Bypass follows the original route and preserves all five settings.
A gain change affects only its own component; Mute sets its weight to zero. Equal gain settings do not imply equally loud components.

Move the balance with the edit
Music Remixer can be used with Fairlight automation: automatable parameters are available for the relevant track’s processor. Establish two useful states first, such as quieter musical detail under a line and the original arrangement afterwards. Then choose the position and duration of the transition.
Open track automation and inspect the available Music Remixer parameters in the Plugin list. Record only the intended change; after the pass, leave the write mode and play the passage again. Check the actual values, Mute states and the timeline before the first change.
A continuous level move can bring an arrangement back gently; a Mute change explicitly turns a group on or off. Choose according to the music and edit, checking the attack, tail and several seconds around each transition. Where several cues share a track, confirm that the retained values also suit the next clip.
Fairlight automation
Record changes, read them back and verify transitions.
↗Ducking
Automatically lower the music track while dialogue is present.

Judge separation in three parts of the scene
Compare a passage with speech, exposed music and the transition between them. The first shows whether the mix problem is solved; the second exposes what changed in the music; the third reveals the intervention itself. Mark the passages so that every version is judged on the same events.
With strong attenuation, listen for residual syllables, uneven tails and changes to neighbouring instruments. With rhythm adjustments, check attacks and the stability of the groove. A useful result preserves the musical features the scene needs even when part of the arrangement is quieter.
Locate a change in the music alone, then judge it with dialogue and effects. Match listening loudness: a louder version can easily seem more expressive. When raising groups, check output peaks and subsequent processing on the way to the final mix.
Words
Can the listener follow the line without extra effort?
Music
Are identity, rhythm, body and the intended emotion intact?
Transition
Is there an abrupt dip, a return of residual vocals or a damaged tail?

When one improvement creates another problem
| Observation | Next check |
|---|---|
| Vocal traces remain after Mute | Compare gentler attenuation and listen to tails. For a clean instrumental version, consider original musical stems or a prepared alternative. |
| An instrument disappears with the vocal | Bring the group closer to its original level and compare whole-track level. Avoid compensating by automatically boosting every other group. |
| Drums become uneven | Check attacks and transitions in different sections of the song. Try a smaller level difference and compare with the original bed. |
| The treatment only sounds better because it is louder | Match listening loudness and inspect Output separately. Replay the line in the complete mix. |
| The balance returns by itself during playback | Check stored automation for the correct track and processor. Separate a manual adjustment from playback of written values. |
| The following music clip sounds wrong | Check Track FX scope and automation on the shared track. Separate musical tasks onto tracks when that makes the project clearer. |

| Rebalance components of finished music | Music Remixer: five musical groups, their levels and Mute states. |
| Lower the whole music track during lines | Ducker: assigned sources and level response on the target track. |
| Place a specific musical movement at an exact moment | Automation: selected values and transitions over time. |
| Fit the duration of a musical clip | AI Music Editor: a separate music-editing tool; Remixer controls do not change clip length. |
| Prepare the dialogue recording | Voice Isolation, Dialogue Leveler and Dialogue Separator address different speech tasks; Music Remixer’s vocal group does not replace them. |
Voice Isolation
Isolate a human voice in a recording with unwanted sound.
↗Dialogue Leveler
Address variation between loud and quiet lines.
↗Dialogue Separator
Balance dialogue, background and room ambience.

Keep the musical decision and its evidence
Record the cue, track, comparison passage, five group levels and Mute states. Note any automation and the positions of its transitions separately. These details explain the decision more clearly than a screenshot of controls alone.
After reopening the project, listen to the same passage and the next music clip. At delivery, check the actual rendered file: dialogue balance, exposed music and transition levels. Keep the original material and the option to bypass Remixer available for further changes.
PRACTICE / NO AUTOPILOT
A small task. A checkable result.
Work in a test copy, listen before and after, and write down what you actually observed. The checklist contains no pre-approved results.
Choose the material
Prepare music and dialogue in a duplicate timeline. Record the specific conflict and preserve the original balance.
Compare three settings
For one group, compare 0, −3 and −6 dB, then Mute. Use the same passage; the values are teaching comparison points.
Check the rest of the arrangement
Listen to rhythm, low end, tails and exposed music. Record any side effect or its absence.
Shape a transition
If the scene needs two states, use automation to move between them. Leave write mode and play the change again.
Record the observation
Compare original and final versions at similar loudness, then check the rendered file. Complete the record from what you heard.
FAQ / BEFORE THE NEXT MOVE
Questions that matter in practice
Is Music Remixer available in the free version of Resolve?
The Resolve 21 manual marks Music Remixer as Studio Version Only. This tool requires DaVinci Resolve Studio.
Reference: Blackmagic Design — DaVinci Resolve 21 Reference Manual · Fairlight Track FX
Why does the guide say Vocals while the window says Voice?
Vocals is the group name in the official manual text; Voice labels its control in the illustration. Both refer to the vocal component of the same five-group system.
Reference: Blackmagic Design — DaVinci Resolve 21 Reference Manual · Fairlight Track FX
Where are Piano and Solo?
The reviewed window contains Voice, Drums, Bass, Guitar and Other, each with level and Mute. Other contains the remaining music. To examine one group alone, mute the others; a separate Solo button is not established here.
Reference: Blackmagic Design — DaVinci Resolve 21 Reference Manual · Fairlight Track FX
Does vocal Mute guarantee a clean instrumental version?
Evaluate that on the actual music. Listen for remaining words, tails and instrument changes. If quality is insufficient, compare gentler attenuation, original musical stems or another cue.
Does Music Remixer distinguish a presenter from a song’s singer?
Its purpose is musical groups, not selecting a particular speaker. For a dialogue recording, first identify the appropriate task for Voice Isolation, Dialogue Leveler or Dialogue Separator.
Reference: Blackmagic Design — DaVinci Resolve 21 Reference Manual · Fairlight Track FX
Why does Effects In not restore the original sound?
Effects In does not bypass Track FX. Compare with Music Remixer itself disabled and check other processors in the signal path.
Reference: Blackmagic Design — DaVinci Resolve 21 Reference Manual · Fairlight Track FX
Can the groups change during the scene?
Yes. Use automation for the processor on the music track. Inspect the available Plugin parameters and replay the recorded transition after leaving write mode.
Reference: Blackmagic Design — DaVinci Resolve 21 Reference Manual · Fairlight Track FX
Does the teaching graph show separation of my file?
No. It illustrates the balance of predefined groups. It does not analyse or play your file, or transfer settings into Resolve.
