Adjusting all of my midi volume curves down?

I need to keep my relative midi volumes the same, but bring down the level on everything. In other words, if I could “select all” in the volume controller lane, then pull down the volume while retaining the individual adjustments, I would be happy. Any solutions? Or a way to do this in the logical editor?

There are presets in the LE that do this or are close enough to modify. Haven’t you looked?

Yes, I looked, but I didn’t find anything. Which preset do you recommend?

I figured it out through trial and error.
The action target had to be set to Value 2, which was what confused me.
