Sometimes, you may notice that one track is not in time with another, even though they are at a similar tempo
There can be several causes for this:
The track is not quantized - some music is not strictly to the grid, meaning that there is some tempo drift throughout the track,
The analysis is off-beat - if a track is quantized, but not on the beat, there is a chance that the beat grid is not aligned to the start of the beat.
Out of phase - Sometimes Beat 1 may not be correctly identified as Beat 1, which can cause alignment issues.
DJ.Studio has a powerful beat-grid editor designed to fix any beat-related issues.

Beat Grid Modes
Before making manual adjustments, check that you have the right beat grid type selected for your track. You can change this in the Track tab in the Studio view:
Fixed — Best for tracks with a consistent tempo. The beat grid is evenly spaced based on a single BPM value.
AI — Adapts to subtle tempo changes, smoothing out variations in intros, outros, and breaks. Great for disco, funk, and older dance music.
AI Flex — Precisely follows tempo changes, including dynamic sections like breakdowns. Ideal for mashups or layering samples over a track, as it preserves the natural tempo variations.
Manual — Selected automatically when you make manual changes to the beat grid or BPM.
Fix Beat Issues - Step-by-step Instructions:
Zoom in to the timeline until you can see both tracks' waveform and beat-grid lines.
You should be able to find where one track's beat is not aligned to the grid correctly
Hover over one of the misaligned beats to open the pop-up menu, and use the tools below to adjust either the full beat grid or individual beats until the beat grid is aligned.
Beat-grid Editor
Hovering over a beat opens a pop-up menu with the following tools:
1 - Reset Grid
Reverts the beat grid to its original state.
2 - Set BPM
Forces a fixed BPM over the entire track. Only use this if you know the track's exact tempo. An incorrect value will misalign the entire grid.
3 - Adjust Full Grid
Shifts the entire beat grid left or right. Use this to correct small offsets.
4 - Drag Individual Beat
Hold this button to shift a single beat left or right (up to 50%). The waveform will compress or stretch to match, and you'll see a percentage indicator at the bottom. The rest of the grid stays in place and only the beat you're adjusting is affected.
5 - Move Beats to the Right
Pushes the current beat and all following beats forward in the timeline. Useful when a beat is missing in the track (common in certain breakdowns or production quirks).
6 - Set Downbeat
Marks the closest beat as the new downbeat (Beat 1 of the bar).
7 - Set First Beat Marker
Manually defines where the track's first beat starts
FAQ
Q: I adjusted a beat, but it keeps drifting out of sync further along the track. Why?
A: This usually means the detected BPM is slightly off. Even a small difference will cause the grid to gradually drift over time. Try switching to a different beat grid mode in the Track tab. AI or AI Flex often detect the true tempo more accurately than Fixed, especially for tracks with subtle tempo variations. If you're on Fixed and know the exact BPM, use Set BPM to correct it.
Q: I used to align acapellas over instrumentals. Why can't I do this with DJ.Studio over a 32-count, and why does the track only snap instead of moving fluidly?
A: DJ.Studio's engine works based on beats, which is why snapping occurs. To adjust more precisely, you can modify the beat grid for the sample. Instead of importing acapellas separately, we recommend generating them within DJ.Studio using stem separation. This keeps the beat grid connected to the acapella, allowing you to create seamless mashups between tracks.
Q: What's the difference between a downbeat and the first beat?
A: The downbeat is the first beat of a bar, in 4/4 time, it's beat 1 out of 1-2-3-4. Every bar has a downbeat. The first beat is the first downbeat of the entire track.
