Efficient Session Management: Instance List
You can now manage other Pro-Q 4 instances in your sessiontogether from a single window.
This makes it easier to review and adjust EQ settings, even in complex mix sessions, substantially reducing thetime and effortrequired across your workflow.
Clicking the button outlined in red alsovisualizes frequency overlapbetween the selected track and other tracks, helping you quickly identify important frequency ranges while mixing.
Intuitive Operation: EQ Sketch
EQ curves can becreated easily as if you were sketching by handwith EQ Sketch, making the workflow smoother than ever.
Low-cut, high-shelf, and bell filters, among others, areapplied immediately, reducing setup time.
You can also fine-tune an existing curveintuitively with your mouse, so you can work more efficiently.
A New Approach to Tone: Spectral Dynamics
Spectral Dynamics is an evolved processing approach to conventional dynamic EQ.
Rather than responding to the input signal level, this moderesponds only to prominent frequency bands.
This lets you control only the ranges that need attention, allowingprecise adjustments without compromising the overall sound.
It is particularly useful for taming harsh resonances or bringing specific frequency ranges forward.
Switching the Sound Character: Character Modes
Clean, Subtle, and Warm are the three character modes—each offering a different approach to sound design.
- Clean mode: Preserves a clear, transparent sound while reducing interference with other sounds.
- Subtle mode: Adds gentle vintage-style saturation for a touch of warmth.
- Warm mode: Adds presence and richness with tube-like saturation.
By choosing the mode that suits your needs, you can pursuethe ideal tonal balancefor different genres and applications.
Other New Features and Improvements
- Free Sidechain Filtering: Allows independent processing of frequency bands.
- Fractional Slope Settings: Enables fine-grained settings such as 3.5 dB/oct.
- Improved Linear-Phase Processing Accuracy: Also suitable for mastering applications.
- New All-Pass Filter Shape: Enables more flexible sonic effects.
- Dynamic EQ Processing That Preserves Clarity: Enables more precise control with less noise than before.
