Store description excerpt
Zzz Polyrhythm is a polyrhythm-focused metronome that lets you layer multiple rhythms simultaneously for advanced rhythmic practice. From classical 2-against-3 to jazz shuffle to contemporary 7-against-11 — instantly build any rhythm pattern you can imagine and play it back with professional-quality voices. Key Features [Base Beat — the time-keeper] - Time signature: any numerator (1-16) and denominator (2 / 4 / 8 / 16) - BPM: precise control from 30 to 240 - Tap Tempo: detect any tempo in real time - 8 voices: Wood Block / Click / Cowbell / Sine / Square / Tick / Hi Click / Low Thud [Layered Rhythms — Overlay] Layer additional rhythms on top of the base beat to construct complex polyrhythms. - Starting beat: not only "beat 1, beat 2" but also fractional positions like "beat 1.5" - Length: whole / half / quarter / eighth / sixteenth / thirty-second note × none / dotted / double-dotted - Subdivisions: any tuplet from 2 to 11 - Shuffle mode: play only the first and last clicks for a jazz swing feel - Timing offset: slide the start/end positions back and forth to fine-tune swing - Voice: choose an independent voice for each overlay from 8 sound presets [Visualizer] Concentric ring display lets you see rhythm timing at a glance. A dot lights up the moment each click fires, helping you grasp polyrhythm structure visually. [Presets] (Premium) Save your favorite rhythm configurations with custom names. Recall with one tap. Browse multiple presets and switch any time. [Phase-preserving BPM changes] Change BPM in the middle of a beat — the rhythm doesn't reset, it smoothly accelerates or decelerates, just like a professional studio metronome.
