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 for more stability and better sound.
A rebuilt beat grid editor for better control.
An improved library with more integrations.
A new and improved stem separation system
Creative new options for effects and samples.
More export options for every workflow.
Optimized performance on both Mac and Windows.
All while keeping your existing mixes and database safe and compatible.
Brand-New Audio Engine
One of the biggest upgrades in 4.0 is the redesigned audio engine.
More stability: Reducing dropouts, glitches, and stutter.
Faster response with less delays.
Improved stems handling: Stems are generated for the full track, not just transitions, making editing more reliable.
Improved exports: Repitch is now always applied to ensure consistent sound quality. The old “disable repitch” and “use limiter” export options were removed to prevent bad-sounding results.
This means you can work with bigger projects and more complex edits without worrying about instability.
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 cleaner vocals, drums, bass, and instruments.
Faster processing: Stems load much quicker, especially on M1/M2 Macs (up to 75% faster).
Full-track stems: Stems are now created for the entire track, not just the transitions. This makes editing, automation, and exporting much more reliable.
Better visuals: Stem waveforms have improved colors, so it’s easier to see what’s happening at a glance.
Automation lines on stems: Add precise volume automation directly on individual stems.
Improved caching: More reliable storage of generated stems, fewer interruptions, and clearer warnings if a project is too large to cache.
Playback while processing: Stems generate in the background so you can keep working without waiting.
This means you can experiment with vocals, swapping out basslines, or creating breakdowns with much less delays and better sound quality.
Rebuilt Beat Grid Editor
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.
New system:
Waveforms + automation are shown together for better context.
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
This 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.
Improved search & sorting: Results are faster and more consistent. Sorting remembers your last setting.
Spotify matching: Paste a Spotify link, and DJ.Studio will automatically find the track on Beatport or Beatsource.
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.
Crate Hackers
Discovery and Charts
Spotify now also browses Beatsource
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. Pitch automation is more responsive.
Sample upgrades: Add fade handles, create loops, 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.
Rekordbox 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
MP3 exports with correct track order tags
Ableton export: Now supports manual transitions
Whether you want to share an MP3 mix, prepare for a Rekordbox set, or continue work in Ableton, DJ.Studio 4.0 makes it seamless.
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: Choose automatic or manual downloads. Updates apply on restart, and you’ll always see when one is available.
Whether you’re on Mac or Windows, DJ.Studio 4.0 runs faster and more reliably than ever.
