Breakbeat basics: how to reverse loop drums with any sampler

After the last video, I received plenty of questions as to how to do reverse looping with your sampler if it doesn’t have that function? (e.g., Maschine still doesn’t have it, Ableton Simpler doesn’t have it).
I did a video on an old trusted method of mine that’s been providing me with seamless breakbeats for a long time now even if all my samplers don’t have a reverse loop ability.
Doing this with Ableton Live and its handy integration with 3rd party audio editors, but this can be done with any daw.
