DrumLock

Stop wasting practice time adjusting your metronome.

DrumLock automatically ramps up your BPM while you play. Set your tempo progression once, then focus on technique.

METRONOME

SPEED TRAINER
Set start BPM, target BPM, increment, and interval. Hit play (from any practice mode). Build speed naturally without interrupting your flow.

RUDIMENT LIBRARY
All 40 essential rudiments with notation. First 10 included. Unlock the rest when you're ready.

CUSTOM ROUTINES
Custom timed practice segments. Add your own images for notation, sticking patterns, or reference notes. Quickly build routines that match how you actually practice.
