How to fix vocals leaking into the intro or outro of an AI track

Club Ready Music keeps intros and outros vocal-free in three layers: the lyric sheet opens and closes with instrumental blocks when Drums-only intro and No vocals in outro are on, the style prompt asks for a drums-only intro and a no-vocals outro, and the vocal gate mutes the vocal stem in those windows after the render. If a take still has a vocal in the intro, check the two toggles, listen to the other take, lengthen the intro, and re-render.

Steps

1. Confirm which take has the problem

Each render gives Take 1 and Take 2, rendered separately. Click each take button on the result panel and listen to the first 30 seconds and the last 30 seconds. Often one take is clean. Download that one.

2. Check the toggles

Under 06 · DJ mix edit make sure Drums-only intro and No vocals in outro are both on. With them on, the lyric sheet starts with [Intro] [Instrumental] (16 bars, drums and percussion only, no singing) and ends with [Outro] [Instrumental] (32 bars, no vocals, no ad-libs). With them off, the model is free to sing from bar one.

3. Remove intro and outro lines from your lyrics

Club Ready Music strips any [Intro] or [Outro] block you typed, but a [Verse] placed first is sung first. If your lyrics open with a soft spoken line that you meant as an intro, delete it or move it after the first chorus.

4. Lengthen the intro

Set Intro bars to 32. The vocal gate window is computed from the bar count and BPM, so a longer intro gives a wider muted window and more room before the first verse. Move Drop at bar to 48 so the arrangement still makes sense.

5. Listen for the vocal in cue

If the model's timed sections report a vocal that starts inside a drums-only intro, Club Ready Music writes a vocal in cue and pulls the intro end cue to that point. Open the file in your DJ software; if intro end sits early, the model sang early and the gate was not applied, which usually means the audio worker or ffmpeg was unavailable at render time.

6. Re-render with the same settings

Press Generate again. The studio remembers your draft, so nothing needs re-entering. Two new takes cost 1 credit. If the problem repeats, add "no vocals until bar 17, instrumental intro" to 02 · Vibe in plain words.

7. Use the clean outro for mixing

For the outro, the same logic applies. With No vocals in outro on and the gate working, the last 32 bars are instrumental. Mix out from the outro start cue.

Tips

• The gate also tames melodic parts in a drums-only intro. It mutes vocals and, during a drums-only intro, fades the melodic stem in over the second half of the intro, so the opening is drums, percussion and bass.
• Hooks are the usual culprit. A hook-only vocal that the model places at the top of the track is common. Put a short [Verse] first so the hook has somewhere later to land.
• Shorter tracks squeeze vocals earlier. At 2:00 with 16 intro bars and 32 outro bars there are few bars left; use 4:00 or more for vocal tracks.
• Hard start does not affect vocals. Hard start only trims leading silence; it never moves the vocal.
• Check with the waveform. The result panel labels INTRO and OUTRO on the waveform so you can see where the loud, vocal-dense sections begin.

Common problems

Both takes sing in the intro. The intro is probably too short for the lyric. Set 32 intro bars, drop at 48, and re-render.

There is a wordless vocal texture in the intro. Breathy pads and vocoded chords are not always in the vocal stem. Add "no vocal textures in the intro" to the vibe and consider removing Vocal chops from featured sounds.

The intro is clean but the first word is clipped. The gate window ends at the intro-end bar; if the vocal starts a beat early it can be cut. Use the other take or shorten the intro by one step so the vocal starts after the window.

The outro has ad-libs. Untick Ad-libs around the drops in Voice options and keep No vocals in outro on. The outro block explicitly says no ad-libs, but the gate is the real guarantee.
