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 — 1 to 20 BPM per step, 20 to 60 seconds per step, Build or Pyramid. Every run lands in your practice history.
Genre presets in the beat builder include metal patterns with double bass foundations. Tweak from there.
Filter the 36,700-sticking pool for patterns with kick or both feet. RLRK, Paradiddle-K — hands and feet trade inside one sticking.
Export patterns as video or notation. Show off your kick speed on social or share exercises with your band.
Run each rung in the Tempo Builder. Build mode ramps you up; Pyramid brings you back down so the last reps aren't your sloppiest. Set 30 to 45 seconds per step.
RLRL @ 120 → 140 BPMBoth feet, one note per 16th, heels doing whatever keeps you loose. Build mode from 120, +4 BPM per step. The tell is evenness, not speed — if the left foot lands lighter, drop back 8 BPM and sit there a full step.
x-RR x-RR @ 140 BPMRest, then two kicks — the classic metal gallop. Start at 140 with the beat builder playing hats and snare over it so the gallop sits inside a groove instead of floating free. +5 BPM per step until the doubles start smearing.
RLRL @ 145 → 160 BPMReturn to alternating 16ths, starting 25 BPM above rung one. Pyramid mode this time — up to your ceiling and back down. Ending slow forces control when your legs are cooked, which is when technique actually changes.
