Metric Modulator

Polyrhythm metronome & rhythm trainer

A metronome built around a beat grid instead of a single click. Divide every beat its own way, string measures of different metres together, then play along and see exactly where each hit landed.

Build the pattern

Split any beat into 1–10 and tap in notes; hold one to accent it. Four tracks, each with its own pattern, mute and solo.

Measures & metres

Every measure has its own time signature. Drop a bar of 7/8 into a 4/4 groove, repeat it, or loop a whole section.

Play along, get scored

The mic, on-screen pads or a MIDI kit mark each hit on the grid — rushing or dragging — and every saved beat remembers your best score.
