Duplicating a snare slice and tuning each copy up produces the classic drum-and-bass ascending pitch fill

A signature drum-and-bass move treats individual slices as tunable material: duplicate a snare slice and pitch each copy up a step or two, then trigger them in sequence to get the classic ascending pitch fill. Because a chopped slice sits on a pad like any sampled instrument, per-slice pitching turns one hit into a melodic run, and the same duplicate-and-retune idea extends to layering pitched vocal or string slices in poly mode. It is an example of treating chopped material as raw sound to be re-pitched rather than as fixed drum hits.

Examples

Duplicate a snare slice twice, tune the copies up a whole step and a minor third, and sequence snare-snare(+1)-snare(+2) for a rising fill.

Assessment

Describe how to build a DnB ascending pitch fill from a single snare slice, and explain why per-slice pitching is possible.
