Use the beat builder and fill builder to create double bass patterns. Practice kick independence with the pattern editor, build speed with the tempo builder.

Build double bass patterns in the beat builder. Alternating 16ths, gallop patterns, blast beats — place every kick note precisely.
The full grid editor lets you place kick notes on any subdivision. Build complex polymetric kick patterns.
Start at a comfortable BPM and ramp up automatically. Log your highest tempo and track progress over sessions.
Genre presets in the beat builder include metal patterns with double bass foundations. Tweak from there.
Build patterns where hands and feet play different rhythms. The grid editor makes polymetric patterns visual.
Export patterns as video or notation. Show off your kick speed on social or share exercises with your band.
