Pro-Q4 Preset Merger

Merge multiple FabFilter Pro-Q 4 preset files into a single preset, reducing the number of plugin instances in your chain.

How to use

Load your .ffp preset files by dragging them in or clicking an empty slot to browse
Click band dots on the EQ display to select or deselect which bands to include in the merge
Use the Overlay view to compare all presets at once, or Tabs to view them individually
Click any band dot to open the floating editor — adjust frequency, gain, Q, shape, slope, stereo, and more. Scroll wheel works on all controls
Use mix sliders to blend each preset's contribution, and toggle switches to enable/disable presets
Click Preview Merge to see the merged result as a white dashed curve on the display
When you're happy with the preview, click Download Preset(s) to save
Use the Undo/Redo arrows or keyboard shortcuts (Ctrl+Z / Ctrl+Shift+Z / Ctrl+Y) to step through changes

Where to find your presets

Pro-Q 4 stores presets as .ffp files in your Documents folder:

Windows & macOS: Documents/FabFilter/Presets/Pro-Q 4
Older macOS: ~/Library/Audio/Presets/FabFilter/FabFilter Pro-Q 4

Saved presets placed in this folder will appear directly in Pro-Q 4's built-in preset browser.

Pro-Q 3 presets

Pro-Q 3 uses a different binary format that isn't directly compatible. To convert, open the preset in Pro-Q 4 and re-save it — this will create a compatible .ffp file you can use here.

How band selection works

Enabled bands are automatically selected for merging. Disabled bands that still have non-default settings (like a specific frequency or gain) are shown with reduced opacity — you can click them to include them in the merge too. Bypassed bands appear greyed out with a dashed outline.

Limitations

Maximum 24 bands per output preset (this is a Pro-Q 4 limit)
If your merge exceeds 24 bands, it will automatically split into multiple presets (A, B, C…)
Smart Merge will suggest combining nearby bands — review each suggestion carefully before applying
