In order for the outro to work in our application, we have some specific guidelines that differ from when you would usually create a production. This, because the final production is mastered and mixed after your submission.
First of all, do not use a fade outro, as the subsequently added vocals will not fade with it. A faded outro can be added once the vocals are in place.
If you don’t have an outro, but rather a cold end from the last chorus, we advise you to bounce an outro of one bar from the tails of reverbs, or what other tracks are lingering.
