What's the difference between Remix and Revise in Song Creator Pro?

Remix regenerates your whole track. It uses your source audio as a melodic and structural scaffold and produces a new version on top, so you can change the style, lyrics, or mood across the entire song. Revise only regenerates a portion of the track while everything else stays intact. Use Remix when you want to transform a track globally; use Revise when you want to fix or rewrite a specific section.

Do I need to write new lyrics to remix a song?

No. You can remix with the original lyrics still in the Lyrics field, and the model will keep them and sing them in the new style. You can also rewrite lyrics entirely, change a single line, or clear the field for an instrumental remix. All three work.

What does Source Influence control?

Source Influence controls how closely the remix follows the structure and melody of your source audio. Higher values keep the remix tight to the original; lower values give the model more room to reinterpret.

Can Remix change the tempo or key of the original?

Yes. Set a new BPM, key, or time signature in the Music Details panel and the remix will shift toward those values. Leave them blank and the model preserves the source's tempo and key. Extreme shifts (like doubling BPM) may reduce quality, so use in moderation.

How to Remix a Song or Create a Song Cover using AI

Remix is Song Creator Pro's tool for reinterpreting an existing track. You upload a song, change the description, lyrics, or settings, and Song Creator Pro generates a fresh interpretation.

This guide walks you through using Remix, from loading a track to tuning the controls.

When to Use Remix

Remix is the right feature when you want to:

Change the genre of a song: turn a pop track into a lo-fi version, an acoustic cover, or a rock arrangement
Rewrite the lyrics while keeping the melody: cover a song with your own words
Shift the emotional feel: take a sad ballad and make it uplifting (or vice versa)
Explore alternate interpretations: batch generate several versions with different descriptions and pick what surprises you
Create variants of your own AI-generated songs: click Remix on any previous result to iterate further

If you only want to change a part of the song (one verse, a transition, the outro), use Revise instead. If you want to add instruments around a single track, use Layer.

Step 1: Upload Source Audio

Click the Remix tab at the top of the interface. In the Source Audio field on the left, click to upload an audio file.

Supported formats: MP3, WAV, FLAC, M4A. You can remix any song, whether it's a track you've generated in Song Creator Pro, a commercial song, a live recording, or a demo.

Note: The model targets the duration of your source audio by default. If your source is five minutes, you'll get a roughly five-minute remix unless you override Duration in Music Details.

Step 2: (Optional) Upload Reference Audio

The Reference Audio field accepts a separate track whose style and timbre are blended into the remix. Reference audio doesn't carry over melody or structure. It only influences acoustic features: vocal timbre, instrument timbre, mixing, spatial sense.

A typical pattern: Source Audio = "the song you want to remix," Reference Audio = "the sound you want it to have."

For example, upload a pop track as Source and a vintage soul record as Reference. You'll get your pop track's melody wrapped in a vintage soul sound.

Leave this field blank if you just want your description to drive the style.

Step 3: Write Your Description

The Description field defines the new style for your remix. This is where you steer the direction.

Be specific. For a deep dive on writing effective descriptions, see the AI Music Prompting Guide. Cover:

Genre: lo-fi hip-hop, orchestral, synthwave, acoustic folk
Instruments: what should play in the new version
Mood: what feeling you want
Vocal style: breathy, raspy, choir, whispered
Production style: polished, raw, lo-fi, live

Example descriptions:

lo-fi hip-hop remix, dusty vinyl crackle, jazzy rhodes piano, boom bap drums, laid-back, nostalgic

orchestral cover, lush strings, cinematic, dramatic swell, emotional, grand

80s synthwave, analog pads, gated reverb drums, retro-futuristic, driving bassline

Step 4: Edit the Lyrics

The Lyrics field works the same way it does in Custom mode. Use [Verse], [Chorus], and [Bridge] tags to mark structure.

You have three options:

Keep the original lyrics: paste them into the Lyrics field so the remix sings the same words in the new style.
Rewrite the lyrics: change any or all of them while keeping the melody via Source Influence and Melody Retention.
Go instrumental: leave the field empty and add "instrumental" to your description.

Step 5: Tune Source Influence

Source Influence (0.00 – 1.00) controls how strictly the remix follows the structure and melody of your source audio.

High (0.5 – 1.0): stays tight to the source. Clearly recognizable as the same song. Best for faithful covers.
Mid (0.15 – 0.5): noticeable reinterpretation but still grounded. Good for genre swaps that should still feel like the original. The default of 0.15 sits at the bottom of this range.
Low (0.05 – 0.15): loose, creative interpretation. The source is more of a suggestion. Great for exploratory remixes where you want maximum creative freedom.

If your remix sounds nothing like the source, raise this. If it sounds too close and your new description isn't coming through, lower it.

Step 6: Tune Melody Retention

Melody Retention (0.00 – 1.00) controls how much of the original vocal melody the remix preserves.

High: strong commitment to the original melodic line. Important if you want a singable cover where listeners recognize the tune.
Low: the model is freer to re-sing lyrics with new melodic phrasing.

Default is 0.25. Raise it when you want a recognizable melody; lower it when you're more interested in a full reimagining.

Source Influence and Melody Retention work together. Both high = tight cover. Both low = a loose remix that only borrows structural DNA. Mix them to taste.

Step 7: Music Details (Optional)

BPM, Duration, Key, Time Sig, and Language work the same as in Custom mode. By default they're inferred from your source audio, so leave them alone unless you specifically want a different tempo or key.

Setting values that conflict with the source can produce interesting results, but large shifts (doubling or halving BPM) often reduce quality.

Step 8: Generate

Hit Generate in the top right. Remixes take about the same time as a Custom generation.

Always batch generate. Set batch size to 2–4 in Advanced Settings. Remix is inherently exploratory, and the first take is rarely the best. Generate multiple versions, listen to all of them, pick your favorite.

Each result in the Results panel has a Remix button. Click it to remix a remix. You can layer these operations to iterate toward a sound you like.

Summary

Generate a song in Custom mode you're happy with.
Click Remix on that result.
Change the description to a new genre ("acoustic coffeehouse version").
Adjust Source Influence and Melody Retention. Lower values give the model more room to drift from the original; higher values keep it closer.
Batch generate 2–3 versions.
Pick the best, click Remix again, change the description again ("orchestral cinematic version").
Repeat until you've explored several alternate universes of the same song.

This loop (generate, remix, remix again) is where Song Creator Pro really shines. Each remix takes seconds and gives you a new creative direction to explore.
