PRACTICE ALONG TO REAL SONGS — NOT JUST A CLICK.

DrumLock turns any song into a guided practice routine. Import your backing tracks, loop the hard sections, slow songs down to learn the parts (with the original key preserved), and drum along. It's also a sample-accurate metronome, the complete PAS rudiment library, a speed trainer, and a session tracker - everything a drummer needs to structure practice, in one app.

WHY DRUMLOCK
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Most metronome apps just click. DrumLock structures your entire practice session.

Learning a new song? Import the recording, set trim points around the chorus you're drilling, and loop it at 75% speed until your hands know it. Building speed on a rudiment? Set the speed trainer and let it climb while you play. Following Stick Control or Syncopation? Photograph the page, drop it into a routine segment, and play to it.

Whether you're a student working through method books, a band drummer learning your setlist, a worship drummer prepping Sunday's songs, or just trying to get better - everything stays in one place.
