What the tool does
Change one section while keeping the source
Set the boundaries, write a focused direction, and compare the returned version with the original.
02
Mark the exact section
Set the start and end points for a section between 6 and 60 seconds and no more than half of the source song.
03
Describe the new part
Write what should happen in the replacement and add style tags that match the sound you want.
04
Change one part, not the whole song
The selected range is regenerated while the rest of the song stays as the surrounding context.
05
Compare the returned take
Play the new version and compare the changed section with the source before deciding what to keep.
06
Keep the original available
The result is returned as another track so the source song is not overwritten by the replacement.
Three steps
Choose the song, mark a valid range, and describe the new section.
Select the source song
Choose a supported generated song from your MusicWave library.
Set the range and direction
Enter the start and end times, then describe the new section and its style.
Generate and compare
Confirm the 5-credit cost, start the replacement, and listen to the returned track.
Before you start
Make the replacement easier to judge
Clear section boundaries and a specific musical job give you a better basis for comparing takes.
Choose a clean musical boundary
Place the start and end near a phrase, bar, or section change when possible.
Describe what changes and what stays
Name the instruments, energy, vocal direction, or lyric purpose of the new part without rewriting the whole song.
Stay inside the real limits
The replacement must be 6–60 seconds and no longer than half the source duration.
Ways to use it

Rewrite a weak chorus
Ask for a stronger or simpler hook while keeping the rest of the generated song.
Change an instrumental break
Replace a solo, transition, or bridge with a different instrument or energy.
Correct a short lyrical section
Use the lyrics controls when you need a targeted vocal change inside the supported time range.
