When FabFilter releases an update, it’s always exciting—and Pro-Q4 is no exception. For me, FabFilter Pro-Q is like the Steve Jobs-era Apple of EQ plugins: reliable, innovative, and consistently excellent. Without hesitation, I purchased Pro-Q4 before even exploring the new features, knowing it would be indispensable for my work and my clients.

In this blog post, I’ll dive into the exciting new features of Pro-Q4, how they work, and why they might become staples in your mixing and mastering workflow.


The Refreshed Interface

At first glance, the Pro-Q4 interface looks familiar, but subtle updates give it a fresh, modern feel. The improved GUI features:

  • Cleaner and sharper visuals.
  • Updated meters and knobs.
  • A smoother, more responsive workflow.

While these changes may seem minor, they enhance the overall experience of using an already excellent plugin.

1. Enhanced Instances View: Simplify Your Workflow

One of the standout features of FabFilter Pro-Q4 is the Enhanced Instances View, a tool designed to streamline your mixing workflow like never before.

What It Does:

  • Track Navigation: Displays all tracks with Pro-Q4 instances in a single, organized view.
  • Zoom and Magnify: Offers adjustable zoom levels and a magnification option, making it easy to focus on specific tracks or EQ curves.
  • Seamless Switching: Allows you to jump between tracks instantly and make quick adjustments.

How It Works:

From the Instances View, you can:

  1. See all active Pro-Q4 instances across your session.
  2. Click on a track to access its EQ settings in detail.
  3. Use the navigation panel to toggle between tracks effortlessly.

Limitations:

While the Instances View enables fast navigation, it does have some restrictions:

  • You can’t perform dynamic EQ adjustments directly from this view.
  • Sidechain setup and other advanced features require exiting back to the individual track.

Why It’s Useful:

For producers and engineers working on complex sessions, Instances View offers a bird’s-eye perspective, saving time and reducing the mental load of navigating through numerous plugins. Whether you’re fine-tuning a mix or managing multiple frequency corrections, this feature makes your workflow more intuitive and efficient.

With Pro-Q4’s Enhanced Instances View, you can now spend less time searching and more time creating.


2. Collision Reference for Frequency Conflicts

This is a game-changer for resolving frequency conflicts. With the Collision Reference feature:

  • You can visually identify overlapping frequencies between two tracks (e.g., kick and 808).
  • Pro-Q4 highlights these conflicts, allowing you to make adjustments with precision.

Workflow Example:

  1. Identify the conflicting frequencies.
  2. Use Pro-Q4’s dynamic EQ to duck specific frequencies in one track when the other plays.
  3. For even more precision, sidechain the frequency adjustments to trigger only when needed.

This feature makes handling low-end clashes, like kicks and basses, much easier.


3. Spectral Dynamics Mode

Pro-Q4 introduces Spectral Dynamics, a feature reminiscent of plugins like Soothe 2. This mode allows you to apply frequency-dependent compression with incredible precision.

Key Aspects of Spectral Dynamics:

  • Targeted Processing: Unlike traditional dynamic EQ, which adjusts the gain across an entire band, Spectral Dynamics hones in on specific frequencies within a band that surpass the threshold, allowing for precise control over problematic areas.
  • Dynamic Control: This mode enables both compression and expansion, providing flexibility in managing unwanted resonances or enhancing desired frequencies.

Practical Applications:

  • Suppressing Harshness: Effectively tame harsh frequencies in vocals or instruments without affecting the overall tonal balance.
  • Reducing Resonances: Address unwanted resonances in recordings, such as room modes or instrument-specific issues, with surgical precision.
  • Enhancing Clarity: By dynamically controlling specific frequency ranges, Spectral Dynamics can enhance the clarity and presence of individual tracks within a mix.

User Experience:

Integrating Spectral Dynamics into Pro-Q 4 streamlines workflows by eliminating the need for separate, complex plugins dedicated to this type of processing. Its intuitive interface makes it accessible as a natural extension of standard dynamic processing, allowing users to achieve precise frequency control effortlessly.

In summary, Spectral Dynamics in FabFilter Pro-Q 4 offers a sophisticated yet user-friendly approach to dynamic frequency control, making it an invaluable tool for mixing and mastering engineers seeking to refine their sound with precision.


4. Harmonic Saturation

FabFilter now includes two new saturation modes:

  1. Subtle: Adds minimal harmonic content for gentle enhancement.
  2. Warm: Introduces tube-like harmonic saturation for richer tonal color.

Testing the Saturation Modes:

  • Using a tone generator, you can see how subtle harmonics emerge in Subtle mode and how more noticeable harmonics develop in Warm mode.
  • While this feature is a welcome addition, its utility may vary depending on your workflow, especially if you already use dedicated saturation plugins.

5. Draw Mode

The Draw Mode feature enables quick creation of custom EQ curves.

Two Ways to Use It:

  1. Click and drag on the GUI to draw curves directly.
  2. Use the new draw tool to set up multiple points in one go.

Why It’s Exciting:

Although it may not seem groundbreaking at first, this feature has the potential to become an indispensable part of your workflow for creating complex EQ curves with speed and precision.


Final Thoughts

FabFilter Pro-Q4 builds on its already stellar predecessor by introducing features that enhance usability and expand creative possibilities. While some features, like Harmonic Saturation, may take time to integrate into your workflow, others, like Spectral Dynamics and Collision Reference, are sure to become indispensable.
