I am brand new at using loops, so please bear with me. I have learned how to build a drum track using loops for a song. However, none of the tutorials explain how to know how many loops a song will require so that you have enough loops to get to the last measure, but not too many so that your ending loop plays at the right time. How do you handle this? I hope my question is clear—if not, please let me know and I will try again!
