Music Gen

Updated July 4, 2026Open the tool

Open Music Gen

Music Gen is Sorceress’s AI music creation tool for making full songs, instrumental tracks, extensions, mashups, and cover-style versions from prompts and uploaded audio. The workspace combines generation controls in the left sidebar with a persistent track gallery in the center, so you can create, preview, organize, reuse, download, and delete your music from one page.

You must be signed in to generate music, upload audio for generation, create projects, and save results. If you are not signed in, the page may show demo tracks, but generation actions will ask you to log in.

What it does

Music Gen can:

  • Create new music from a text prompt in Simple mode.
  • Create music from lyrics, descriptions, style tags, titles, vocal settings, and advanced controls.
  • Generate instrumental music with no vocals.
  • Produce two track variations for each music generation.
  • Extend an existing Music Gen track from a chosen point.
  • Extend an uploaded audio file.
  • Combine two uploaded audio files into a mashup remix.
  • Create a cover-style version from uploaded audio while preserving the melody.
  • Generate lyrics separately from a lyrics prompt.
  • Save generated tracks to your Music Gen gallery.
  • Play, seek, rename, reuse, download, delete, search, select, and organize tracks.

Workspace overview

Music Gen is split into two main areas:

  • Left sidebar — generation controls, including Simple/Advanced mode, model selection, creation mode tabs, prompt fields, upload controls, and the main action button.
  • Center gallery — your generated tracks, project tabs, search, selection tools, playback controls, waveform previews, downloads, and track details.

A navigation bar for audio tools appears at the top of the page.

Creation modes

The left sidebar has four creation tabs:

| Mode | Use it for | | --- | --- | | Create | Generate a new song from a prompt, lyrics, description, style tags, or instrumental idea. | | Extend | Continue or recreate part of an existing Music Gen track, or extend an uploaded audio file. | | Mashup | Upload two audio files and generate a combined remix. | | Cover | Upload one audio file and create a cover-style version that preserves the source melody. |

A model selector appears at the top of the sidebar. Available choices are V5.5, V5, V4.5+, V4.5, and V4. The default selection is V5.5.

Simple and Advanced mode

At the top of the sidebar, switch between Simple and Advanced.

Simple mode

Simple mode is for fast prompt-based generation.

  1. Choose Simple.
  2. Open the Create tab.
  3. Describe the music you want in the prompt box.
  4. Click Create.

The Simple prompt field shows a 500 character maximum note. In Simple mode, the prompt is required. You can also press Enter while focused in the prompt field to start generation, as long as you are not inserting a new line with Shift+Enter.

Advanced mode

Advanced mode gives you more control over lyrics, style, vocals, title, and generation behavior. It is the default editing mode in the current interface.

Advanced Create options include:

  • Lyrics / Description — The main lyrics text for vocal tracks, or an optional description for instrumental tracks.
  • Manual / Auto lyrics — Available for non-instrumental Advanced Create. Manual lets you write lyrics. Auto hides the lyrics field and lets lyrics be generated from your style direction.
  • Styles — Comma-separated descriptors such as genre, mood, instrumentation, production style, vocal style, era, or energy.
  • Exclude styles — Traits you want the generation to avoid.
  • Song Title — Optional. In Create mode, this field accepts up to 80 characters.
  • Vocal Gender — Auto, Male, or Female.
  • Weirdness — A 0–100% slider. Higher values invite more unusual or unexpected results.
  • Style Influence — A 0–100% slider. Higher values make the style field more strongly guide the result.
  • Instrumental (no vocals) — Generates music without vocals.

In Advanced Create mode, generation is enabled when you provide enough direction: lyrics/prompt text, style text, Auto lyrics, or Instrumental mode.

Create new music

Use Create when you want a brand-new song or instrumental track.

Quick steps

  1. Open Music Gen.
  2. Sign in if prompted.
  3. Choose Simple or Advanced.
  4. Select a model from the model dropdown.
  5. Open the Create tab.
  6. Enter a prompt, lyrics, description, or style tags.
  7. Optional: enter a song title.
  8. Optional in Advanced mode: choose Manual or Auto lyrics, set Vocal Gender, Exclude styles, Weirdness, Style Influence, or Instrumental.
  9. Click Create.
  10. Two placeholder cards appear in the gallery and update into generated track variations when ready.

Prompting tips for Create

For Simple mode, write the prompt as a compact brief: genre, mood, instruments, vocal style, and intended use.

For Advanced mode, separate the concept into fields:

  • Put actual lyrics in Lyrics when you care about words and structure.
  • Put genre and production direction in Styles.
  • Use Exclude styles for things you specifically do not want.
  • Use Instrumental for background music, game loops, ambience, battle music, menu themes, and cinematic cues without vocals.

Extend a track

Use Extend when you want to continue from an existing Music Gen result or from uploaded audio.

There are two ways to provide source audio:

  • Drag a completed track from the gallery into the Extend drop area.
  • Click Upload Audio File and choose an audio file.

Extend an existing Music Gen track

You can start Extend from a completed track in two ways:

  • Drag the track card into the Extend drop zone.
  • Click the track card’s Extend button.

After a track is selected, Music Gen shows a source panel with the track title, cover art if available, a preview button, and a waveform editor.

The waveform editor is divided into:

  • Keep — the portion before the selected point.
  • Recreate — the portion after the selected point that will be regenerated or continued.

Drag on the waveform to move the split point. You can also edit the timestamp field manually in minutes:seconds format. The Select All button resets the extension point to the default full-track selection.

Steps:

  1. Open the Extend tab.
  2. Drag in a completed track or click its Extend button.
  3. Wait for the waveform to load if needed.
  4. Drag the split marker or type a timestamp to choose where the extension begins.
  5. Use the preview button to audition from the selected point.
  6. Add lyrics describing what should happen after the selected point.
  7. Add style direction if desired.
  8. Optional: enter a title, choose Vocal Auto/Male/Female, switch Instrumental, or change the model.
  9. Click Extend.
  10. Two extended variations appear in the gallery.

Extend an uploaded audio file

Uploaded audio extension is useful when your starting point was created outside Music Gen.

Steps:

  1. Open the Extend tab.
  2. Click Upload Audio File.
  3. Choose an audio file.
  4. Wait for the upload to finish.
  5. Set Extend from in seconds. The interface notes that 0 = from end.
  6. Add lyrics or a description for the continuation.
  7. Add styles, title, vocal settings, Instrumental, and model if desired.
  8. Click Extend.

The Extend upload area lists MP3, WAV, and OGG, with a maximum length note of 8 min.

Create a mashup

Use Mashup to combine two uploaded audio files into a remix.

Steps:

  1. Open the Mashup tab.
  2. Upload Audio 1.
  3. Upload Audio 2.
  4. Optional: describe the mashup style in the prompt box.
  5. Optional: add style tags, such as “Pop” or “EDM.”
  6. Optional: enter a song title.
  7. Click Mashup.
  8. Two mashup variations appear in the gallery when ready.

The Mashup upload UI lists MP3, WAV, OGG, M4A, FLAC, and AAC. Both upload slots must be filled before the Mashup button can run.

Create a cover

Use Cover to create a new version of uploaded audio while preserving the melody.

Steps:

  1. Open the Cover tab.
  2. Upload an audio file.
  3. Describe the cover style in the prompt box.
  4. Add style tags, such as “Jazz,” “Acoustic,” or “EDM.”
  5. Optional: enter styles to avoid.
  6. Optional: enable Instrumental.
  7. Optional: enter a song title.
  8. Click Cover.
  9. Two cover variations appear in the gallery.

The Cover upload UI lists MP3, WAV, and OGG, with a maximum length note of 8 min.

Generate lyrics

Music Gen includes a separate lyrics generation flow in the current tool logic. Enter a lyrics prompt, run lyrics generation, and review returned lyric options. Generated lyrics can then be used as material for Create mode.

If lyric generation is still running, the lyrics area shows a loading state. If it fails or takes too long, Music Gen displays a lyrics error message.

The center panel is your Music Gen gallery. It shows generated tracks and in-progress placeholders. Signed-in users see saved Music Gen tracks from their account; signed-out visitors may see demo content.

A track card can show:

  • Cover image, when available.
  • Track name.
  • Prompt or tags summary.
  • Up to several style chips, with an indicator when more styles exist.
  • Duration.
  • Waveform preview.
  • Play/Stop button.
  • Download button.
  • Extend button, when the track can be extended.
  • Reuse Settings button.
  • Track Details button.
  • Delete button.

The gallery initially loads a set of visible cards and loads more as you scroll.

Playback and seeking

Click Play on a track card to preview it. The button changes to Stop while playing.

When a waveform is available, click within the waveform to seek. If the track is not already playing, clicking the waveform starts playback and seeks to that position. The waveform highlights playback progress as the audio plays.

If waveform extraction is still in progress, the card shows Loading waveform.... Playback and download may still be available once the track has audio.

Renaming tracks

Click the title of a completed track to rename it. Type the new name, then press Enter or click away to save. Press Escape to cancel while editing. Empty names are ignored.

Reuse settings

Click Reuse Settings on a completed or failed track to copy its saved settings back into Create mode. This can restore available fields such as:

  • Prompt or lyrics.
  • Style tags.
  • Song title.
  • Model.
  • Simple or Advanced mode.
  • Instrumental setting.
  • Vocal setting.
  • Excluded styles.
  • Weirdness.
  • Style Influence.

Reuse Settings is useful for iterating on a result: restore the setup, make a small change, and generate again.

Track details

Click the info button on a track card to open the details panel. Depending on what is available for that track, it can show:

  • Track name and creation date.
  • Style tags.
  • Lyrics or prompt.
  • Model.
  • Simple or Advanced mode.
  • Instrumental status.
  • Vocal setting.
  • Excluded styles.
  • Weirdness.
  • Style Influence.
  • Duration.

The details panel includes Reuse Settings and Close buttons.

Failed tracks

If a generation fails, the card displays a failed state and an error message when available. Failed cards include options to Reuse the settings or Remove the card.

Downloads

Use the download button on a completed track card to download an individual MP3.

If more than one completed track is visible in the current filtered view, Download All appears above the gallery. It downloads all completed tracks in that view.

In selection mode, you can download only selected completed tracks.

If the browser cannot directly save the file, Music Gen opens the audio in a new tab. From there, use your browser’s save controls.

Projects and organization

Music Gen supports lightweight project organization with tabs above the gallery.

All Tracks

All Tracks shows every track in your Music Gen gallery. You can drag a track back onto All Tracks to remove it from a project.

Create a project

Click the folder-plus button beside the project tabs. A new project is created and selected automatically.

Move tracks into projects

Drag a completed track card onto a project tab to move it into that project. Tracks created while a project tab is active are added to that project.

Rename a project

Select a project tab, then click the pencil icon. Type the new name and press Enter or click away to save. Press Escape to cancel.

Delete a project

Select a project tab, then click the trash icon. Music Gen asks what to do with the tracks in that project:

  • Keep tracks (move to All Tracks) — Deletes the project but keeps its tracks.
  • Delete tracks too — Permanently deletes the project and its tracks.
  • Cancel — Leaves everything unchanged.

Search, selection, and bulk actions

Use the search field to filter tracks by name, prompt, or tags. The search applies within the active project tab or across All Tracks.

When completed tracks are visible, click Select to enter selection mode. In selection mode you can:

  • Click completed tracks to select or deselect them.
  • Use Select All to select all completed tracks in the current filtered view.
  • Download selected tracks.
  • Delete selected tracks.
  • Click Cancel to exit selection mode.

Bulk delete requires confirmation and cannot be undone.

Limits and visible requirements

  • You must be signed in to generate music, upload audio for generation, or create projects.
  • Each music generation returns 2 variations.
  • Simple Create requires a prompt.
  • Advanced Create requires enough direction: lyrics/prompt, styles, Auto lyrics, or Instrumental mode.
  • Mashup requires two uploaded audio files.
  • Cover and uploaded Extend require one uploaded audio file.
  • Upload-based Extend and Cover show a maximum audio length note of 8 min.
  • Upload labels list different accepted formats by mode: Extend and Cover list MP3, WAV, OGG; Mashup lists MP3, WAV, OGG, M4A, FLAC, AAC.
  • Music generation can take several minutes. If it takes too long, the gallery card may show a timeout failure.
  • Lyrics generation may also time out and show an error message.

Tips for better results

  • Use comma-separated style tags in Advanced mode: genre, mood, tempo, instruments, vocal tone, production style, and era all help.
  • For vocal tracks, put the actual lyrics in Lyrics and use Styles for musical direction.
  • For instrumental tracks, enable Instrumental and describe the use case: “tense dungeon ambience,” “uplifting town theme,” “retro boss battle,” or “calm crafting menu loop.”
  • Use Exclude styles to steer away from unwanted genres, vocal qualities, or production traits.
  • Keep Simple prompts concise and direct.
  • Try Auto lyrics when you know the genre and mood but do not want to write lyrics manually.
  • For extensions, choose the split point carefully. The left side is kept; the right side is recreated or continued.
  • Preview from the extension point before generating to make sure you selected the right moment.
  • Use Reuse Settings to iterate from a result you like instead of rewriting prompts from scratch.
  • Compare both variations before deleting; two outputs from the same setup can differ substantially.

Troubleshooting

“Sign In Required”

You need to log in before using Music Gen generation features. Click the sign-in button or go to the login page, then return to the tool.

The Create button is disabled

In Simple mode, enter a prompt. In Advanced mode, add lyrics or a prompt, add style tags, switch to Auto lyrics, or enable Instrumental.

Mashup will not start

Both Audio 1 and Audio 2 must be uploaded successfully. If the button says Uploading..., wait for the upload to finish.

Cover or uploaded Extend will not start

Upload one audio file first and wait for the upload to complete. If the upload fails, remove the file and try again.

I dragged a track into Extend but nothing happened

Only completed Music Gen tracks that are available for extension can be used this way. Try using the track card’s Extend button instead, or upload an audio file in the Extend tab.

The waveform keeps loading

Waveforms are prepared after audio is available and may take time to appear. You can usually still play or download a completed track even if the waveform preview has not finished loading.

A generation failed

Open or read the failed card’s error message. Use Reuse to restore the settings, adjust the prompt, styles, or upload, and try again. You can also remove the failed card from the gallery.

A generation is taking a long time

Music generation can take several minutes. The gallery shows placeholder cards while work is in progress and may show playable preview audio before the final track is fully complete. If the generation takes too long, the card may change to a failed timeout state.

Download opens in a new tab instead of saving

If your browser cannot directly fetch the audio for download, Music Gen opens it in a new tab. Use the browser’s save or download controls from that tab.
