How to set intro bars on an AI-generated DJ track

Set intro bars under 06 · DJ mix edit in the Club Ready Music studio: pick 8, 16 or 32 bars, with 16 as the default. The number feeds the style prompt sent to the music model, the lyric sheet that keeps vocals out of the intro, and the "intro end" cue point written into your MP3 and WAV. A 16-bar intro at 126 BPM is about 30 seconds of mixable groove before the track opens up.

Steps

1. Open the studio and fill in the song first

Go to /studio, name the track, describe the vibe and pick up to five genres. The intro setting works with everything else, so set the musical brief before the arrangement.

2. Find the DJ mix edit panel

On desktop the arrangement controls sit in the middle column under the heading 06 · DJ mix edit, marked BEAT-GRIDDED · 4/4. On a phone they are on step 4 of 5, DJ settings. The first row is Intro bars.

3. Choose 8, 16 or 32 bars

Tap one of the three buttons. The choice shows up straight away on the result panel as the IN value of the IN 16 · OUT 32 tag, and the waveform label changes to match.

• 8 bars: a short lead-in. Good for radio-style edits, warm-up sets where you will not blend long, or tracks that need to hit fast.
• 16 bars: the default. Enough room for a 32-beat blend from the previous track while staying tight.
• 32 bars: a long, DJ-tool intro. Pick this for techno, progressive and melodic sets where you layer tracks for a minute or more.

4. Decide whether the intro should be drums only

The Drums-only intro toggle sits just under the bar buttons and is on by default. With it on, the style prompt asks for an intro of drums and percussion only, and the lyric sheet opens with an [Intro] block marked instrumental for exactly that many bars. Turn it off if you want melodic elements or pads from bar 1.

5. Check the first drop and total length still make sense

Drop at bar must be later than the intro ends. With a 32-bar intro, set the drop to bar 48. The track length under Length should leave room for the intro, a breakdown and your chosen outro: a 2:00 track at 126 BPM is only 63 bars long, so a 32-bar intro and 32-bar outro would leave almost nothing in the middle.

6. Render and check the cue point

Press Generate. When the take is ready, the MP3 and WAV carry an intro end cue at the bar count you chose, computed from your BPM. Load the file into your DJ software and you will see the marker at the end of the intro.

Tips

• Convert bars to seconds with bars × 4 × 60 ÷ BPM. At 128 BPM, 16 bars is exactly 30 seconds; at 174 BPM it is 22 seconds.
• Match the outro of the track before it. If your crate is full of 32-bar outros, a 32-bar intro gives you an even, phrase-aligned blend.
• Longer intros suit lower energy. A warm-up track with a 32-bar drums-only intro gives the room time to settle. Peak-time tracks usually want 16.
• Vocal tracks still stay clean. Club Ready Music keeps lyric lines out of the intro block of the lyric sheet, and when the vocal gate is enabled it mutes the vocal stem during the intro window even if the model sings early.
• The intro counts toward the length. A 5:00 track with a 32-bar intro and 64-bar outro at 126 BPM spends almost 3 minutes on its edges. That is a DJ tool, not a radio record.

Common problems

The intro sounds shorter than I set. Music models follow bar counts approximately. If the generated intro is close but not exact, use the intro end cue as your mix-out guide, or set the intro one step longer and trim in your DJ software.

There are vocals in the intro. Make sure Drums-only intro or at least a vocal track with a labelled [Verse] is in place, and that the vocal gate is enabled on the server. If vocals still leak, try the other take; the two takes are rendered separately. Re-render with 16 bars instead of 8 if the model keeps starting the vocal early.

The drop lands before the intro has finished. Check that Drop at bar is at least the intro length. The studio does not stop you from choosing 16 for both, but the model will then be asked for a drop at the same bar the intro ends, which usually makes a very abrupt opening.

The track is too short overall. Intro and outro bars come out of the total length. Raise Length to 4:00 or 5:00, or drop the outro to 16 bars.
