Why Upgrade to DJ.Studio 4.0?
DJ.Studio 4.0 isn’t just an update, it’s a complete rebuild in many areas.
You’ll get:
A new audio engine
A new and improved stem separation system
A rebuilt beat grid editor for better control.
An improved library with more integrations.
Creative new options for effects and samples.
Elastique pro extension for high level
More export options for every workflow.
All while keeping your existing mixes and database safe and compatible.
Stems: Faster, Clearer, Smarter
We’ve completely reworked how stems are generated and used in DJ.Studio 4.0.
Higher-quality models: New stem separation models deliver higher quality, cleaner vocals, drums, bass, and instruments.
Faster processing: Stems load much quicker.
Full-track stems: Stems are now created for the entire track, not just the transitions. This makes editing and automation the same in tracks and transitions.
You can show 4 stems view, 2 stems view and the regular waveform.
Better visuals: Stem waveforms have improved colors, so it’s easier to see what’s happening at a glance.
Automation lines on stems: Add volume automation directly on individual stems.
Playback while processing: Stems generate now in the background so no long waits before the entire track is separated.
This means you can experiment with vocals, swapping out basslines, or creating breakdowns with much less delays and better sound quality.
The beat grid editor has been redesigned from scratch for precision and ease of use.
Old problems solved:
Dragging the waveform used to move the whole grid by accident.
Switching between grid/time view was confusing.
UI was clunky, making automation edits impossible in beat grid view.
Users didn’t realize that touching the waveform moved the entire beat grid, not just a single beat — often leading to unintended changes.
New system:
The waveform is clearly visible, now shown in a slightly different color
Automations are now also visible in beatgrid view
Beats are no longer directly draggable, instead, you get a pop-up menu with clear options:
Drag or reset individual beats
Adjust the full grid
Move beats forward/backward in the timeline
Set downbeat or first beat marker
Apply fixed BPM over the track, or set BPM from a point for tempo changes
Reset to original AI/fixed grid if needed
Checkout this article for the detailed description how these buttons gives you precise control and prevents accidental mistakes. Perfect for aligning tricky tracks, live recordings, or songs with tempo shifts.
Improved Library & Integrations
The library has been upgraded to make it easier to browse, manage, and discover tracks.
New home screen layout: All library features are clearly listed, so you can quickly jump to your collection, playlists, or integrations.
Charts tab: Browse trending music directly inside DJ.Studio.
Expanded integrations:
Beatport & Beatsource Shop: Browse, preview, and buy tracks directly inside DJ.Studio. Previews can be swapped seamlessly with purchased full tracks via Legalize Mix.
Spotify matching: Paste a Spotify link, and DJ.Studio will automatically find the track on Beatport or Beatsource, which was added to this conversion.
Crate Hackers: browse Crate Hackers playlists
This makes DJ.Studio a true hub for your music, whether tracks come from your computer, Beatport, or other DJ software.
Improved Tools & Effects
We’ve added more flexibility and creative power to help shape your mixes.
EQ Effect Block: EQ can now be used as an effect, placed in blocks, and saved as reusable presets.
Improved effects workflow: FX blocks resize and move consistently, even on stems and sample lanes.
Sample upgrades: Add fade handles for quick Volume fade in&outs, copy samples with their effects, and move multiple samples while keeping their timing.
More options = more creativity when building mashups, remixes, or detailed transitions.
Export Options
Exporting has become more flexible and powerful.
Improved exports: Re-pitch is now always applied to ensure consistent sound quality. The "Use limiter" has moved from the Export screen to the Master tab.
Rekordbox & Serato export with edits: Cuts, loops, and pasted sections are now included when you export to Rekordbox.
More formats:
WAV/FLAC with selectable bit depth
M3U playlists
Ableton export: Now supports manual transitions
Performance & Workflow
We’ve optimized DJ.Studio for speed and smoother day-to-day use.
Apple Silicon Macs: Stems up to 75% faster on M1/M2 processors.
Windows: Smarter GPU handling — auto-selects best GPU and uses DirectML fallback if needed.
UI performance: Home screen loads faster, zooming and navigation are smoother.
New Update System: At Settings > General you can choose for automatic or manual downloads. Updates apply on restart, and you’ll always see when one is available.
Incompatibilities between DJ.Studio 3.1 and 4.0
It is important to be aware of the following differences between Dj.Studio 3.1 and DJ.Studio 4.0:
DJ.Studio 4.0 does not have a Vinyl brake effect yet.
If you have used the Vinyl brake in projects and you export the project with DJ.Studio 4.0, the effect will not be applied, potentially messing up your transitionIn DJ.Studio 4.0 we removed the stems block because it didn't work like it should (you could only grab the handles on 1 side of the block and it didn't support volume automations per stem).
In DJ.Studio 4.0 you can now enable stems on the full track and then either mute a stem for a small part or use the volume automation lines for more advanced control.In DJ.Studio 3.1 Echo/Reverb effect on Samples were hearable after the end of the sample. In DJ.Studio 4.0 we introduced the concept of "dragging the effect outside of the sample", allowing you to define exactly how long the effect should last.
This means that Echo/reverb effects that you configured in 3.1 will stop immediately after the sample stops, unless you made it longer yourself.
More detailed release notes
The DJ.Studio team has worked on this DJ.Studio 4.0 release since April, so there are a lot of things that got improved.
Below is a more detailed list, but this list doesn't describe every change because then the list would become too long ;-)
Audio Engine
[changed] Export > Repitch audio settings has been removed. Repitch is now always applied automatically during export, because it could only lead to bad sounding exports if you disabled this setting.

Stem separation
[new] Stems are now always created for whole tracks.
