I wrote up a tip about using the sample playback in a tape form, where you can speed it up and slow and reverse it:
You can spread that across patterns and change the loop parameters as long as you don’t re-trigger the loop, and I do that a bunch here, I only trigger the main voice loop a few times, mostly just pulling the loop points around.
Another fun tip: If you have a sample with the reverb already in the sample, like a long dubby spring reverb on a snare, you can liven up the sample by putting a random wave LFO on either the panning or the fine tune, with a short fade in.
