The trick is to ensure when you do the cross fade is to do it slightly before the beat. As was said if you do it on the beat you could get clicks. Most DAWs will allow you to expand the view and adjust the “slice point”. In Reaper and Cakewalk it is far easier to adjust this after the part is inserted. Simply insert the part then drag back the splice point to a flat part before the beat. Note do not drag back the beat but the point of the cross fade.

Adding a file to demonstrate what I mean. Blue Original and Green is the replaced part, Brown the fill.
