How to add ad-libs and an auto-tune effect to AI vocals

In the studio click Voice options and tick Ad-libs around the drops and Auto-tune effect under Effects. Ad-libs add "ad-libs and vocal hits around the drops" to the vocal direction, and auto-tune adds "tight pitch-corrected auto-tune effect on the voice". Both are instructions to the music model rather than plug-ins on the finished file, so pair them with lyrics and a delivery that suit the sound.

Steps

1. Pick a track style that wants them

Ad-libs and auto-tune belong on trap, hip-hop, drill, Jersey club, reggaeton, slap house and modern pop. Put one of those genres first in your blend under 03 · Genres so the model treats the effects as natural rather than out of place.

2. Open Voice options

Under Voice choose Female or Male, then click Voice options. The Effects group is on the right of the dialog on desktop and near the bottom on a phone.

3. Tick Ad-libs around the drops

This asks for vocal hits, shouts and responses near the drops. It works best with Delivery set to Rap or Sung and How much vocal set to Full lead or Hook only. Put the drop where you want the hits with Drop at bar under 06 · DJ mix edit; 32 is the default.

4. Tick Auto-tune effect

This asks for a pitch-corrected, auto-tune sound on the lead. It is most convincing with the Smooth or Sweet / pop character chips and a sung or half-sung delivery. Gritty or Raspy chips fight the effect.

5. Write ad-lib lines yourself if you want specific words

The model invents ad-libs on its own, but you can steer them. In your lyrics put short parenthetical phrases after a line: "Run it back (yeah)" or "Lights out (skrrt)". Short bracketed words in a [Drop] block, such as "(hey) (hey)", land as hits.

6. Keep the outro clean

Leave No vocals in outro on. The outro block of the lyric sheet says "no vocals, no ad-libs" and, when the vocal gate is enabled, the vocal stem is muted in the outro window. You get hype in the middle and a mixable tail.

7. Generate and compare the takes

Press Generate and listen to both takes around the drops. Ad-lib density varies between takes; pick the one with the balance you want.

Tips

• Fewer words, more hits. Ad-libs stand out when the main lyric leaves space. Hook-only vocals with ad-libs make a strong DJ record.
• Match the BPM. Trap ad-libs sit naturally at 140 to 150 BPM; hip-hop at 85 to 100. See picking a BPM for hip-hop.
• Name the ad-lib style in the vibe. "Atlanta-style ad-libs, triplet flow" or "crowd-hype shouts" in the 02 · Vibe box focuses the model.
• Auto-tune needs melody. Give the chorus a clear melodic line to tune to; spoken verses with auto-tune sound flat.
• Effects cost nothing extra. They are part of the 1-credit render.

Common problems

No ad-libs are audible. The model sometimes keeps them quiet. Add explicit parenthetical ad-libs to the lyrics, set Delivery to Rap, and raise the energy to Peak time.

Ad-libs ran over the intro. Keep Drums-only intro on so the intro block says no singing, and rely on the vocal gate. If a take still has early hits, use the other take or see fixing leaked vocals.

Auto-tune sounds too subtle or too robotic. The effect is a style direction, so results vary by take. For more, add "heavy auto-tune, T-Pain style" to the vibe; for less, remove the checkbox and write "lightly tuned pop vocal" instead.

The effects came through on the wrong voice. Effects apply to whatever voice is chosen, including a cloned voice. Check the Cloned voice select if the voice is not what you expected.
