I think what they are referring to is a similar feature to ‘Loopy Pro’ app, in that it records the tail of the loop i.e the delay/reverb trail and mixes this into the loop to make a perfect loop which includes the tail rather than just making a hard cut of the end of a loop.
That would be a cool feature.
I think this would work well in conjunction with another user request for making perfect loops based on bar or step length.
