Instead, a lot of these loops are very similar, the recording quality is not at all optimal (or even consistent, for that matter), and it feels more like an introduction to jazz, rather than a comprehensive tour of the genre.
Worse still, the sliced formats aren't particularly well constructed, so it can be a bit of a chore to create lowing, natural-sounding patterns.
On the plus side, all the loops are well organised into BPM-marked tempo groups.
