This comprehensive guide will walk you through everything you need to know about Serato's Pitch 'n Time DJ and RX3 - from basic functionality to advanced techniques that will transform your mixing approach. We'll explore how these powerful algorithms can help you maintain audio quality while manipulating tempo and pitch, opening new creative possibilities for your performances.
Understanding Serato Pitch 'n Time DJ: The Fundamentals
Serato Pitch 'n Time DJ is a premium expansion pack for Serato DJ Pro that replaces the standard time-stretching algorithm with a more sophisticated engine. This upgrade significantly improves sound quality when changing a track's tempo, allowing for more extreme tempo adjustments without the audio artifacts commonly associated with time-stretching.
What Sets Pitch 'n Time DJ Apart
At its core, Pitch 'n Time DJ offers superior audio quality when manipulating tracks. The standard time-stretching algorithms in most DJ software tend to introduce unwanted artifacts when you push beyond modest tempo changes - typically resulting in that dreaded "chipmunk effect" or grainy, distorted sound when slowing tracks down significantly.
Pitch 'n Time DJ uses advanced algorithms that preserve transients (the attack portion of sounds like drum hits) and maintain harmonic content even during extreme tempo changes. This means you can push tracks much further from their original tempo while maintaining professional sound quality.
Key features include:
High-quality time-stretching up to ±50% without significant audio degradation
Independent pitch and tempo control
Key lock functionality that maintains harmonic integrity
Keyshift capabilities for harmonic mixing
Elastic pitch for creative effects
Installation and Setup
Before diving into techniques, let's ensure you have Pitch 'n Time DJ properly installed:
Purchase Pitch 'n Time DJ from the Serato website or authorized retailers
Ensure you have Serato DJ Pro installed and updated to the latest version
Log into your Serato account within Serato DJ Pro
The expansion pack will automatically activate once purchased and linked to your account
In Serato DJ Pro settings, navigate to the "Expansion Packs" tab to confirm activation
Restart Serato DJ Pro to apply the changes
Once installed, Serato DJ Pro will automatically use the Pitch 'n Time algorithm for all time-stretching operations, immediately enhancing your mixing capabilities.
Essential Techniques with Pitch 'n Time DJ
Now that you understand what Pitch 'n Time DJ offers and have it properly set up, let's explore the fundamental techniques that will transform your mixing approach.
Precise Tempo Matching
The most basic application of Pitch 'n Time DJ is achieving precise tempo matching between tracks without affecting their tonal qualities:
Load two tracks into separate decks in Serato DJ Pro
Ensure Key Lock is enabled (typically indicated by a lock icon near the tempo fader)
Adjust the tempo fader to match the BPM of your tracks
Notice how even with significant tempo changes (e.g., taking a 128 BPM track down to 100 BPM), the sound quality remains intact
With standard algorithms, such dramatic changes would result in audible degradation. Pitch 'n Time DJ maintains clarity even with these extreme adjustments, giving you greater flexibility when selecting tracks for your sets.
Harmonic Mixing with Keyshift
One of the most powerful features of Pitch 'n Time DJ is its ability to shift the key of tracks independently from tempo:
With a track loaded, locate the key display in Serato DJ Pro
Click on the key display to open the key change interface
Use the semitone controls to shift the key up or down
For harmonic mixing, adjust tracks to compatible keys (e.g., same key, relative minor/major, or harmonically compatible keys)
This capability allows you to create mixes that are not only beatmatched but also harmonically aligned, resulting in smoother, more musical transitions. For DJs exploring the art of independent music distribution and production, this skill is particularly valuable as it demonstrates a sophisticated understanding of musical structure.
Elastic Pitch for Creative Effects
Elastic Pitch is a unique feature that allows for temporary pitch bending without affecting the overall tempo:
Assign Elastic Pitch controls to your controller (typically through MIDI mapping)
During playback, use these controls to temporarily bend the pitch up or down
Release to return to the original pitch
This technique is perfect for creating tension before drops or adding subtle variations to familiar tracks. It's particularly effective for genres like techno and house where pitch effects are commonly used to build energy.
Advanced Pitch 'n Time DJ Techniques
Once you've mastered the basics, these advanced techniques will help you leverage the full potential of Pitch 'n Time DJ.
Extreme Tempo Transformations
Pitch 'n Time DJ excels at handling extreme tempo changes, opening up creative possibilities:
Genre Blending: Take tracks from drastically different genres (e.g., a 174 BPM drum and bass track and a 120 BPM house track) and bring them to a common tempo without losing audio quality
Half-time/Double-time Transitions: Create dramatic shifts by halving or doubling the tempo while maintaining key
Ambient Breakdowns: Dramatically slow tracks for atmospheric interludes while preserving audio fidelity
These techniques allow you to incorporate a wider range of music into your sets, breaking genre boundaries while maintaining professional sound quality.
Key Changing for Creative Transitions
Beyond basic harmonic mixing, you can use key changes creatively:
Key Stepping: Gradually shift the key of a track during playback to create tension or prepare for the next track
Emotional Modulation: Shift from minor to major keys (or vice versa) to change the emotional impact of a section
Harmonic Mashups: Layer tracks in complementary keys to create unique mashups
These techniques require a good ear and understanding of music theory, but they can create powerful moments in your sets that stand out from standard mixing approaches.
Combining Tempo and Key Manipulation
The true power of Pitch 'n Time DJ emerges when combining tempo and key adjustments:
Tempo-Synced Key Changes: Gradually change both tempo and key to smoothly transition between tracks with different musical characteristics
Energy Control: Use tempo to control energy while using key changes to maintain or alter the emotional tone
Custom Remixing: Transform tracks on-the-fly by significantly altering both parameters
This level of control allows you to essentially remix tracks live, creating unique versions that fit perfectly within your set's flow and energy.
