About

Riddiments

Features
Read full description

Riddiments is a rhythm instrument for your pocket — a practice tool with the precision of a metronome and the expressiveness of a drum machine. Most metronomes give you one click. Riddiments gives you up to four independent rhythmic voices, each with its own time signature, sound, and feel — all locked to a single tempo. Different time signatures don't drift apart; they interlock into polyrhythm. It's the difference between counting along and actually hearing how the parts fit together. SEE THE BEAT, NOT JUST HEAR IT Four visualizations, one tap to switch between them: • Circular — a beat wheel with a playhead sweeping the ring. The signature view. • Waterfall — notes rise toward a NOW line, so you can read what's coming. • Timeline — every voice as gems on one lattice. Tap to edit, even while playing. • Notation — real single-line percussion notation with sticking letters, accents, flams, and drags. STICKINGS YOU CAN TRUST The built-in library covers the PAS International Drum Rudiments plus hybrid rudiments, rolls, grooves, and ostinato exercises — every sticking verified against published sources. Flams and drags play as true grace notes, on the correct hand. BUILD REAL TECHNIQUE • Practice mode: timed sessions, count-in, gap click, and automatic tempo progression to push your speed up gradually. • Tempo Lock, lead-hand flipping, and Alternate Lead each bar. • 18 built-in percussion voices — snare, kick, hi-hats, toms, claves, and more. • Per-lane swing, volume, and mute. Every control is live — changes land instantly, without stopping. MADE TO LIVE ON A STAND Every control works while you play. Tempo, transport, session time, and mute state stay readable from drumstick distance. Light and dark appearance. Save your own patterns, and your last session is always waiting when you reopen the app. Designed in the spirit of good tools: useful, honest, and quiet until you need it. Universal — one app for iPhone, iPad, and Mac.
