| FabFilter Pro-Q 2.05 Mar 19, 2026 |
Fixed a bug that could cause another parameter to jump to its maximum value when editing e.g. the frequency in the EQ parameter value display and then pressing Tab on Windows. Fixed a bug that could cause spurious vertical lines in the spectrum display on displays with a width of more than 4096 pixels. Fixed a bug that caused two undo states to be added after editing a value by typing it in the parameter value display on Windows (so you had to click Undo twice). Improved error messages when loading an invalid preset. Minor bug fixes and small improvements. |
| FabFilter Pro-Q 4.11 Mar 19, 2026 |
Fixed problems with interface sizing and scaling that could cause the interface to end up too large or impossible to resize on all platforms, but particularly with Logic Pro on macOS. Clicking the slope value in the parameter value display (for a LP/HP band) will now open a slope menu instead of letting you change the slope by dragging up or down. The new behavior is the same as clicking the slope button in the band controls. Fixed a bug that caused the Side Chain option in the EQ Match reference menu not to work. Fixed a bug that sometimes caused loading a previously saved EQ Match reference spectrum to result in an empty spectrum. Fixed a bug in EQ Match that caused comparing a signal to itself to yield around a 1 dB difference, instead of a flat spectrum. Fixed a crash in the instance list that could occur when the track order is updated (for example on stop/start playback) while the mouse is over an instance. Fixed a bug that caused the incorrect latency to be reported when using spectral bands in combination with Very High or Maximum processing resolutions. Fixed a bug that caused the processing warning icon to be shown when using Zero Latency processing, while the (unused) processing resolution parameter was still set to Very High or Maximum. Fixed a possible crash when having two Pro-Q 4 windows open showing the instance list. Fixed a crash when closing the interface with a text editor open on Windows (for example when double-clicking to type a parameter value). Minor bug fixes and improvements. |
