Using DxO Pure Raw with On1 Photo Raw

That’s exactly what I am doing and, as you say, it mostly works well. However, on one of my trips I underexposed a lot of images and Pure Raw doesn’t do a good job with this. Back in On1, the result looks odd even if is hike up exposure and rescue contrast…
If Pure Raw had an exposure slider, it would be fine. Or maybe I should work out how to do the basic edits in On1 and save as a DNG. I don’t know how that can be done.
