Ahem, not related I guess but a new user was asking if it was possible so he could finally leave behind logic pro so please devs..
Consider a render option called "2nd pass rendering"
It would make reaper play the render area once around before then finally capturing/rendering down on the second time round.
That means reverb tails and non linear processes (min phase EQ) would actually then loop properly (as the reverb would now be fully active at the start of the rendered file and not dry) meaning that the render would loop properly.
This would be a massive massive feature for anyone needing to render out loops.
The workarounds to get this to work at the moment are arduous and involve multiple renders and editing so please add it in at some point.
I'll go and make a feature request if there isn't one.
