Adding Drums to a Sample From a Record

I would like to import a sample and then add drums without altering the sample length, so matching the beat tempo to the tempo in the sample. I could line up where the bass and snare etc. should hit with the sample by matching it visually but that will be kinda tedious and slow, is there a better way?

You can use “Analyze > Regular Interval Labels” to create something like grid where to snap your drum sounds to. That’s the easiest way.
