Master your sense of time by practicing with a drum genius! Created after years of research by Mauro Battisti (experienced musician and specialist in the field), Drumgenius is the choice of top players and leading music academies. An ever-growing rhythm library to practice on — 500+ loops across 21 styles, reproducing real grooves by the best drummers and following authentic patterns of rhythms from around the world. The loop player is packed with dedicated functions that put you in full control of every practice session. In-depth descriptions and insights offer a deeper understanding of the world of rhythm. Plus, using Metrogenius, the smart built-in metronome — with a fully editable library of 9 meters + 22 clave patterns — you can explore everything from basic patterns to the most complex rhythmic cycles. Easy Organization & Backup: Personalize your library by renaming loops, creating custom groups, and starring favorites. Save different practice setlists into single backup files to switch setups whenever you need, restore in a single tap on new devices, or share with friends, students, and fellow musicians.
