At a Glance

Design your own grid with up to 8 rows and any subdivision from 1–8 per row. Create polyrhythms, odd meters, and custom click patterns in seconds. Play on upbeats, 16th subdivisions, or leave measures silent for focused practice. Layer rhythms simultaneously or cycle between A and B patterns.

Three customisable sounds let you build the click you need. Choose from classic drum machine samples, recorded percussion, or synth waveforms. Fine tune the volume, pitch, and tone to taste. Link sounds together for quick edits.

Designed for Musicians

See your rhythm light up in real-time. Lock a sound and paint patterns instantly, then shift them in any direction to explore variations. Create claves, phrase any time signature how you want, and internalise off-beat subdivisions that traditional metronomes can't touch.

Share patterns instantly with links and QR codes—perfect for teachers distributing exercises or musicians collaborating. Save setups as presets, set custom sound defaults, and choose exactly what to load—grid, tempo, sounds, or any combination.

Whether you're a drummer working on polyrhythms, a music student learning odd meters, a teacher creating exercises, or a producer programming beats, MRT-7 adapts to your needs.
