You recorded a two-hour set last night. Something went wrong in a transition around the 45-minute mark. You remember the moment: the mix felt slightly off, the energy dipped when it should have risen. Now you are sitting at your laptop, scrubbing through the waveform to find it.

Four minutes later you find the spot. You listen back. You diagnose it. The fix is obvious.

The scrubbing was the problem, not the diagnosis. And the problem started before you pressed record.

The two jobs cue points do

Every rekordbox tutorial and cue point guide covers the live performance role. Set a cue at the track’s clean entry point, fire it for a tight mix-in, mark the outro so you know when to start blending. That is the standard playbook, and it works.

What those guides skip is the recording role. A cue set at a clean phrase entry does not just help you during the set. It places a navigation marker at exactly the point where something meaningful happened. When you review the recording, that marker is the difference between finding your transitions in seconds and scrubbing for minutes.

These two jobs are related but not the same thing. Live navigation is about that night — real-time, in the room. What you need from your recording is a different kind of legibility. The prep that optimises one does not automatically optimise the other, and that is the gap this article addresses.

What a cue on the wrong beat costs you

The most common cue placement mistake is setting the marker on the first beat of a track’s intro rather than the first beat of its first full phrase.

A 16-bar intro sounds fine in a warm room. The DJ hits the cue, the track layers in, the crowd does not notice the entry. On playback it sounds different. You hear every bar of that intro before any real energy arrives, and the mix-in point lands somewhere in the middle of a buildup rather than at the phrase boundary where the arrangement opens up.

If you had cued to the first phrase entry — bar 17, where the full groove kicks in — the mix-in point in your recording maps exactly to where the music started doing something. The transition makes sense on playback in a way the live room might have masked.

A cue on the intro’s first beat is a safety marker for performance. A phrase-entry cue is something different — it is where the recording becomes navigable. You can place both.

Memory cues vs hot cues: the recording-prep choice

Hot cues are designed to be triggered during performance. They require a button press — the CDJ-3000 has eight hot cue buttons, colour-coded and laid out in a row — and you need to hit the right one in real time. They are useful live.

Memory cues work differently. Export your library once and those markers are baked into the track data — on any CDJ that opens the file, they sit in the waveform as positional references from the moment the track loads. You cannot accidentally fire one mid-mix.

For recording preparation — marking phrase entries in advance, before the session starts — memory cues are the right tool. They stay where you put them, they show up on the hardware waveform when the track loads, and they do not compete with your hot cue layout.

rekordbox 7.2.19 includes Intelligent Cue Creation, which reads your placement habits and uses phrase analysis to propose cue positions on new tracks. Version 7 also introduced Phrase Detection, an AI feature that analyses musical phrase structure in a track and marks the results on the waveform. Both are worth running as a starting point — but automatic phrase detection does not replace the judgment call of where you actually plan to mix in, and it does not know which phrase entry you intend to use on a given night.

A five-point system for recording prep

The five cue positions below map to specific uses during recording review. Not every track needs all five. Most need at least three.

1. Clean phrase entry The first beat of the first full phrase, not the intro’s opening beat. Your mix-in point. In the recording, it marks where the energy arrived — the start of something, not the start of an intro.

2. First big moment or vocal entry Where the arrangement shifts for the first time — a vocal drop, an added element, a breakdown opening up. Useful for reading the energy arc in review: did the track do what you expected it to at that point in the mix?

3. Peak energy point The track’s highest-energy moment. In a recording review, this tells you whether the energy arc landed where you expected. It is also the natural clip point if you are pulling highlights from a longer set.

4. Outro start Where the outro begins. The signal in performance to start listening for your next record is the same point that marks the transition zone in the recording — where any blending you did becomes visible on the timeline.

5. Safe mix-out Your fallback. The last reliable mix-out point before the track ends — in the recording, the exit marker if the mix ran longer than expected or the next track took time to settle.

These five positions give you a skeletal map of each track in the waveform. When you open the recording after the set, you are not reading an unmarked timeline.

Finding phrase boundaries

Electronic music is built on repeating blocks of 8 and 16 bars. A phrase is one of these blocks — the span of time before the arrangement fundamentally shifts.

The most direct way to find phrase boundaries by ear is to count bars. One bar is four beats in 4/4 time, which covers almost all DJ-oriented electronic music. Eight bars is 32 beats — count to 32 and you are at the next phrase. A 16-bar intro is 64 beats before the first phrase entry.

In rekordbox’s waveform view, phrase boundaries often appear as visible changes in the transient pattern. The dense cluster of kicks and hi-hats either thickens or thins at the phrase edge. Energy drops slightly before a new section opens. Count through a track once, mark the boundaries you find, then loop a few bars around each to confirm the arrangement shifts there.

Phrase boundaries in house, techno, drum and bass, and most other DJ genres fall at bar 8 or bar 16. Exceptions exist — some tracks build on 4-bar phrases, some live-recorded or ambient material has no regular structure — but 8 and 16 are the positions to check first.

Your cue structure when reviewing in Ohm

Ohm embeds automatic track markers in the recording waveform at each point where it identifies a track playing during your set. Those markers are named and timestamped — each one a direct jump point. Tap it and you are at the transition.

A DJ who mixes at phrase boundaries will find that Ohm’s automatic markers land at the transition points they expected. The waveform is immediately readable: markers align with mix-in points, the energy arcs between them are visible, and the set’s structure is legible at a glance.

Mix off-phrase and the markers land somewhere in the middle of transitions — technically accurate timestamps, but positioned partway through a blend rather than at a clean entry. The recording is harder to read quickly, and the transitions are harder to clip or diagnose.

The phrase prep discipline described here is what makes the difference. Mixing to phrase entries is not just a musical habit. It is the preparation step that makes your recording navigable the moment the set ends.

The How to Review Your Own Recordings and Actually Improve From Them article covers what to do once the recording is open: what to listen for, how to diagnose transitions, how to extract lessons. The cue prep work here happens upstream of all of that.

Common mistakes

Setting cues on the intro’s first beat instead of the first phrase entry. The most consistent issue. It feels correct in the moment because the intro starts there. On the recording, it places your navigation marker four or eight bars before any real mix point, and the transition looks messier on the waveform than it sounded live.

Too many hot cues cluttering the performance layout. Eight hot cue slots fill up fast if you are trying to use them for both live triggers and recording navigation markers. Use memory cues for recording-prep positions. Reserve hot cues for your live performance triggers. Keeping the two purposes separated makes both more reliable.

Skipping cue prep on familiar tracks. These are the tracks that get skipped. Makes sense — you know the record. But phrase boundaries differ between extended and original mixes, and a track you have played a hundred times still gets cued at the wrong bar more often than you would expect. Prep it anyway.

The discipline builds. Mix to phrase boundaries consistently and each recording review starts from a position of legibility — the waveform tells you what happened rather than making you decode it. Prep takes less than a minute per track once the habit is set.

Before your next session, open your playlist in rekordbox and mark your phrase entries. If you are going through pre-session prep more broadly, the Five Checks to Run Before Recording Your DJ Set covers the other variables worth confirming before you press record.
