Synth, recorder, piano roll, metronome, tuner — eight focused tools that fit in your pocket and complement the desktop DAW you already use, rather than replace it. Everything runs on your device.

Practice with real drums, not a drum machine. Drum Lab is a library of original, professionally recorded drum loops. Built for musicians who want to practice, play along, and get better, not just listen. Every loop is a real performance, seamlessly looped, organized by feel so you can find exactly the groove you need. Browse jazz, funk, R&B and hip hop, rock and pop, world rhythms grouped by region (Brazilian, Latin, African and more), and odd meters grouped by time signature. Tap a loop and it locks in at its tempo instantly - no setup, no syncing, just drums. **Built for practice, not just playback** - Slow a groove down or speed it up, from 0.5× to 1.5×, without changing its pitch - Tap the BPM to type an exact tempo - Loop just the bars you're working on, snapped to the bar lines - Practice Mode gradually raises the tempo as you play - +5 BPM every 4 bars by default, and you set the step and how often - Built-in metronome locked to each loop's grid, in quarter, eighth or sixteenth notes, or on beat 1 only - Optional two-bar count-in before the loop starts - Download loops for offline practice anywhere - no connection needed - Save favorites and build your own practice playlists - Light and dark mode **Producer Mode: make it sound like a record** - Tape, Punch, Echo and Reverb in a rack of classic studio gear - Start from a ready-made tape, or dial in your own sound and save it - Echo locks to the loop's tempo, and Blend sets how much of the effects you hear - Bounce (Pro): export exactly what you hear as a WAV that loops seamlessly in any DAW **Try it free** Pick 3 loops to keep, free forever, full length, with tempo control and Practice Mode. Every other loop plays a 10-second preview, so you can hear the whole library first. Unlock Drum Lab Pro with a one-time payment for every loop, every practice feature, Bounce, and the original WAV files to export, royalty-free, into your own music - no subscription, ever. Whether you're working on your time, your feel, or just want something real to play along to, Drum Lab gives you drums that sound like a drummer, because they are one.
