Extend Feature Guide

Introduction

With the Extend feature on MusicAI, you can make your song longer and add new ideas without starting from scratch.
It helps you build extra sections that match your existing track while leaving room for creativity.

Choose the song to extend

Open the AI Music Generator and, in the workspace panel on the right, select the song you want to extend to open the Extend view. This is where you edit and generate the new extended part of your track.

Set where the extension starts

Use the timeline slider or type a specific time to decide where the extension should begin. The AI keeps your original audio up to that point and starts writing new music from the selected position.

Customize the extended section

Use the Instrumental option to choose whether the extended part should include vocals or remain instrumental only.
In the Extend Style field, describe the style you want for the new section, such as genre, mood, instruments, or atmosphere.

Fine-tune with advanced options

Click Advanced options to access deeper controls:

• Exclude Styles: Styles you do not want in the extended part.
• Vocal Gender: Vocal type for the extension.
• Weirdness: Controls how experimental the new part is.
• Style Influence: How strongly the style description guides the result.
• Audio Influence: How closely the new section follows the original track.

When you are satisfied, click Generate and wait for the AI to create the extended part of your song.
