Scratch Editor
The Scratch Editor allows you to add vinyl-style scratch effects to your mixes, create custom scratch patterns, and use scratching as part of transitions between tracks.
Scratch Blocks
Scratch effects are represented as Scratch Blocks on the timeline.
You can add a Scratch Block by:
Right-clicking in the timeline
Using the Effects tab
Using the Effect Automation dropdown
Scratch Blocks can be moved, resized, and positioned anywhere in your mix.
When zoomed out, blocks snap to beats. When zoomed in, they snap to 1/8 notes for more precise placement.
Scratch In vs Scratch
There are two types of scratch behavior:
Scratch In
Scratches are integrated into a beat, drop, or transition.
Commonly used to introduce a new track.
Scratch
Scratches are performed over the currently playing audio.
Commonly used on vocals, beats, or musical phrases.
A triangle inside the Scratch Block indicates its direction. If you drag a block beyond its start or end point, DJ.Studio automatically converts it between Scratch and Scratch In mode.
Echo Scratch Transition
DJ.Studio includes an Echo Scratch transition preset.
This transition:
Applies an echo effect to the outgoing track.
Scratches the incoming track into the mix.
You can also use only the scratch effect by navigating to:
Transition → Effects → Effect In → Scratch In
Scratch Pattern Editor
Selecting a Scratch Block opens the Scratch Pattern Editor.
The editor allows you to create and customize scratch movements using a pattern language.
Pattern Language
Uppercase letters (A–Q): audible vinyl movements
Lowercase letters (a–q): silent movements, similar to a closed crossfader
R: releases the record back to normal playback
. (dot): slows the movement between actions
Additional Controls
Pattern Graph
Displays the scratch movement visually over time.
Easing Slider
Controls how mechanical or natural the scratch motion feels.
Use Track Audio
Preview scratches using the actual track audio instead of the default scratch sample.
Save Preset
Save custom scratch patterns for reuse in future projects.
Scratch Presets
DJ.Studio includes a collection of built-in scratch presets created with professional turntablists.
You can mark presets as favorites to keep them easily accessible.

Double and Half Tempo Matching
DJ.Studio automatically recognizes when two tracks are related by double or half tempo.
For example:
75 BPM and 150 BPM
80 BPM and 160 BPM
90 BPM and 180 BPM
When a double or half tempo relationship is detected:
Both tracks retain their original BPM.
No pitch shifting is applied.
Beats are aligned automatically.
This behavior also applies to content placed in sample lanes.
Existing vs New Mixes
The automatic double/half tempo system is applied only to newly created mixes.
Existing projects continue using their original tempo behavior to avoid altering previously completed work.

Switching the Timeline Between Time and Bars
The Studio timeline can display either:
Time (minutes and seconds)
Musical bars
To switch between the two views:
Open the Studio view.
Click the time/bars display in the upper-left timeline card.
Toggle between Time and Bars mode.
DJ Set Export Improvements
rekordbox and Serato Exports
DJ.Studio exports for rekordbox and Serato can now include additional processing elements that were previously excluded.
Earlier versions only exported track edits such as:
Cuts
Loops
Stems
Paste operations
Version 4.2 adds support for exporting:
Samples
Samples can be exported in two ways:
Bundled with tracks
The sample is merged into the track it belongs to
Separate audio clips
Samples are exported as independent audio files.
Sample numbering continues after the last track in the mix.
Example:
15 tracks in mix
First exported sample becomes file 16
Transition Effects
Exports can now include transition processing created in:
Transition → Equalizer
Transition → Effects
Transition → Stems
Effect Blocks
Standalone effect blocks placed on:
Tracks
Samples
Transition sections
can now be included in exported DJ sets.
Exporting to djay Pro and VirtualDJ
DJ.Studio can export DJ sets for:
djay Pro
VirtualDJ
This allows projects created in DJ.Studio to be transferred into those platforms for further performance or editing.
Other changes and Fixes
System Requirements
Starting with DJ.Studio 4.2, macOS Big Sur (11.x) is no longer supported.
Users running macOS Big Sur can continue using earlier versions of DJ.Studio, but version 4.2 and newer require a more recent version of macOS.
Studio
Fixed an issue where BPM in Mashup Mode could become locked at 400 BPM.
Fixed resizing for elements that were only one beat long.
Fixed Tempo Lane behavior when switching from Manual back to Auto mode.
Stems
Fixed alignment issues that could occur when using Mute Stems (MS).
Missing File Detection
Fixed an issue where the Missing Files dialog could repeatedly appear after opening projects with missing media.
Improved folder scanning so unreadable subfolders no longer stop the entire search process.
Export
Fixed a Windows-specific issue affecting Dropbox exports for the DJ.Studio mobile app.
Performance and Stability
Several improvements were made to memory usage and project stability, including:
Reduced memory usage when saving projects.
Fixed multiple memory-related issues in large projects.
Fixed a memory leak related to repeatedly resizing transition windows.
Improved Library audio streaming performance by switching to chunked audio streaming.
VST Plugins
Plugin parameters now update immediately when selecting a different track, even when playback is paused.
This ensures that displayed parameter values always reflect the currently selected track and its automation settings.
