FabFilter have just released FabFilter Pro-Q 2.01, a free update for existing Pro-Q 2 users with improvements to the piano display and solo mode, along with various bug fixes. FabFilter Pro-Q 2.01 is fully compatible with Pro-Q 2.00 and they recommend all Pro-Q 2 users to upgrade to version 2.01.

What’s new in FabFilter Pro-Q 2.01?

• Improved the piano display: you can now drag multiple selected curves in parallel, and double-clicking the piano display creates a new curve at this position.

• Improved solo mode for Bell and Notch filters to better isolate the frequency area of interest. When soloing Low/High-Cut filters, the Q value now always stays the same, making it easier to just fine-tune the frequency.

• Added support for displaying the current EQ curve in Avid’s S6 control surface.

• Fixed a bug in the Auto Gain feature: it would not correctly compensate bands that are in per-channel mode (L/R or M/S). For example, splitting a stereo band would double the auto gain effect. This now works as intended while preserving compatibility with existing saved sessions. When working with an existing session that uses Auto Gain, simply disable and re-enable Auto Gain to get the new behaviour.

• Fixed a bug in the VST3 plugin that could cause the sound to stay the same (not using the new parameter values) after using Undo or loading a preset.

• Fixed a bug in the VST3 plugin that caused the saved parameter state to be ignored when opening a saved Audio Montage in WaveLab 8 (this fix is not needed for WaveLab 8.5.10).

• Fixed a bug in the VST3 plugin that caused the latency to be reported as zero when opening a saved Audio Montage in WaveLab 8 and 8.5.

• Fixed a bug in Natural Phase mode that could cause an incorrect frequency response with some rare combinations of frequency and slope settings with Low Cut and Notch filters.

• Fixed a bug when double-clicking a control to enter a new value: clicking outside the input box now accepts the new value while previously it would discard it.

• Fixed a bug in the AU plugin: pressing Cmd+Q to quit the host while Pro-Q 2 was in full screen mode would cause it to crash.

• Fixed a bug when zooming out in the display when Analyzer Freeze is enabled: this would create a large blob on the left side of the display in the analyzer.

• Fixed a bug with Full Screen mode in the 32-bit VST2 plugin in Cubase on Mac OS X when ‘Always on top’ was enabled: the plugin window would float on top of the full screen window. In addition, keystrokes are now correctly passed to Cubase in this case (e.g. playback start/stop).

• Small other bug fixes and improvements.

It is interesting that most of the bug fixes relate to platforms other than Pro Tools. Maybe that reinforces a comment made to us over and over that although developers complain about Avid and the problems of writing plug-ins for Avid, actually they tell us that getting the plug-ins to work in other formats is much more problematic.
