The previous answer didn't do the trick. I have a click track set to an unknown tempo. In fact it may not even be a discrete tempo, it could be 110.34 for example. So I have a regioun where I know it's example one bar of 4/4. I want to use this region to reset the tempo grid precisely so this region will then define the tempo grid. Really easy to do in Pro-Tools and in Ardour, haven't figured out how to do it in PreSonus yet!
