Hey,
If you do not know, then there is such an opportunity to save loops in other sequencers (save as loop (Ableton), 2th path render (Reaper) ).
This is where the tail of the effect mix in with the start of the loop and gives the impression of continuity and nothing breaks abruptly at the end of the loop.
In other words, the internal process should be like this one:
1. Render to the project window with a tail of 2 bars
2. Trim the tail
3. Move the tail to a new track at the beginning
4. Tail fade out.
5 Export audio.
Thanks.
Den.
