# Advanced Studio Tools

> Power tools for finished tracks — replace a section, get word-synced lyrics, convert stems to MIDI, and generate a music video.

These tools operate on tracks you've already generated — refining, extending, and repackaging finished work. They're available from the creation menu and inside the [Studio](/using-the-studio) AI dock.

## Replace Section — 50 credits

Regenerate just one part of a song without rebuilding the whole track. Pick the source track, select a start/end time range, describe what should happen in that section (optionally with full lyrics, style tags, and vocal gender), and the AI infills only that range. Providers: Suno (50 credits) or MusicGPT (60 credits). The result is a new edited track — your original stays untouched.

Use it to fix a weak bridge, rewrite one verse, or swap a chorus while keeping everything you already love.

## Timestamped Lyrics — 10 credits

Get **word-by-word synced lyrics** for any of your generated tracks. Perfect for lyric videos, karaoke-style displays, or checking exactly where each line lands.

## Stem-to-MIDI — 20 credits

Convert a finished [stem separation](/create/stems) into MIDI notes — take the bassline or melody of a track into your DAW as editable notes. (For converting a raw audio file directly, the free [Audio to MIDI](/create/audio-to-midi) tool does that without a stem split.)

## Music Video — 30 credits

Generate an **MP4 visualizer video** for a finished track — a ready-to-post video for YouTube, TikTok, or Instagram without opening a video editor.

## Frequently asked questions

<AccordionGroup>
  <Accordion title="Why do these tools need a generated track?">
    They work on the generation itself (its stems, lyrics timing, and structure), which is only available for tracks created on Vocuno — not arbitrary uploads.
  </Accordion>

  <Accordion title="Can I chain them?">
    Yes — a common flow: Replace Section to fix the bridge → Timestamped Lyrics for the lyric video → Music Video for the visual → master and release.
