Overview

The interface of FabFilter Pro-Q 4 is simple and straightforward. The interactive EQ display fills the plug-in window, and lets you create and adjust EQ bands using the mouse. When you create or select bands, the band controls will appear, floating above the display, positioned under the selected bands. Using the band controls, you can change the settings of the currently selected EQ bands. The bottom bar offers features like processing mode (zero latency, Natural Phase or linear phase), the instance list, spectrum analyzer settings, global bypass, character modes, and output settings.

• Interactive EQ display
  The interactive EQ display shows you in a glance what's going on and lets you easily create and edit EQ bands. See Display and workflow.

  FabFilter Pro-Q 4 can work in zero-latency mode, Natural Phase mode or in linear-phase mode with variable processing resolution. See Processing mode.
• Instance list
  The Instance list button in the center of the bottom bar opens the instance list, providing easy access to all other Pro-Q 4 instances in your session. This is also the starting point for EQ Match, which lets you match the spectrum of a reference signal, and collision detection. See Instance list.
• Spectrum analyzer
  Via the Analyzer button, you can enable or disable the real-time spectrum analyzers for the pre-EQ, post-EQ and external signals, and customize the analyzer settings. See Spectrum analyzer.
• Character modes
  The Character mode button chooses between Clean, or the new Subtle or Warm character modes, introducing vintage non-linearities and warmth to your mixes. See Character mode.
• Output options
  On the far right of the bottom bar, you can bypass the entire plug-in, invert the output phase, enable or disable auto-gain, show/hide the output metering, apply an overall gain scale and adjust the output level and panning. See Output options.
• Full Screen mode, resizing and scaling
  The Resize button at the far right of the bottom bar lets you change the interface size and scaling. In addition, click the Full Screen button in the top-right corner of the interface to let Pro-Q 4 fill the entire screen. See Full Screen mode, resizing and scaling.
• EQ Sketch
  The EQ Sketch button starts EQ Sketch mode, which lets you draw the entire EQ curve in one step. See EQ Sketch.
• Piano display
  Using the Piano Display button, you can toggle between the normal frequency scale and a piano keyboard display, via which you can easily quantize band frequencies. See Piano display.
• MIDI learn
  MIDI Learn lets you associate any MIDI controller with any plug-in parameter. See MIDI Learn.
  
• Presets, undo, A/B, help
  With the preset buttons, you can easily browse through the factory presets or save your own settings so you can re-use them in other songs. The Undo, Redo, A/B and Copy buttons at the top of the plug-in interface enable you to undo your changes and switch between different states of the plug-in. Finally, the Help menu provides access to help and version information. See Loading presets and Undo, redo, A/B switch.
