Just like when you double-click on a single region to open the properties window and set the gain, is there a way to set the gain for a whole bunch of selected regions at once? Cut/boost gain only brings the gain down/up by 1 dbl, I need to enter my own dbl.
Select the regions that you want, and press Alt + 6 or Alt + 7 to change the gain of the selected regions.
If you want to make subtle increments I think the only way is to combine or consolidate all the regions, and then open the edit dialog.
