When selecting a full clip or group of clips (not just a single edit point), and pressing the "F" key with no modifiers, the current behavior in 12.6 is to create a fade in, crossfade, and fade out according to the settings in Preferences.
However the length of each fade and crossfade defaults to 10 ms.
I would like to be able to set a default for the lengths of these fades.
Side note: In the Batch Fades dialog, I created a preset called "starting point" that included the fade shapes and default fade lengths that I wanted. Using "Import Settings" in the Fades Dialog in the "Default Fade Settings" in "Preferences", I imported "starting point" from the "Pro Tools > Fade Presets..." folder with the hope that the fade length as well as the fade shape would carry over with the setting.
Unfortunately did not work, only the fade shape results with still a 10ms length.
