MathRonome vs Backrooms Piano

MathRonome is a polyrhythmic visual metronome designed for musicians, music teachers, and students. Watch two independent rhythms orbit in sync, hear every beat, and build your rhythmic vocabulary from simple time-keeping to complex polyrhythms. FEATURES • Two independent metronomes (M1 & M2) with visual ring animation • Subdivisions from 2 to 5 (free) or 2 to 32 (Pro) • Common Pulse — hear and see the pulse both layers share, with the moments they meet accented on the dial • Divisible Beats — long-press any beat to split it into equal sub-beats (triplets, quintuplets, sixteenths) and toggle each one • Toggle individual beats on/off to create custom patterns • Randomize beat patterns for sight-reading practice • 1 sound preset (free) or 4 presets: Percussion, Drums, Marimba, Piano (Pro) • Adjustable tempo from 1 to 120 RPM • Independent volume and mute controls per metronome • Background audio — keep practicing while using other apps • Bluetooth audio latency compensation slider • Interactive tutorial with step-by-step guidance • Works on iPhone and iPad PRO UPGRADE ($2.99, one-time) • Full subdivision range: 2 to 32 • All 4 sound presets • Swap M1 and M2 subdivisions instantly • Switch Mode: automatically alternate between metronomes Perfect for: • Music students learning polyrhythms (3:4, 5:7, etc.) • Teachers demonstrating rhythm concepts visually • Drummers and percussionists building independence • Any musician wanting to strengthen their internal clock No subscription. No ads. One optional upgrade. New in 1.2: Common Pulse. Switch on the pulse the two layers share and watch the polyrhythm resolve — a subtle shaker marks the smallest beat both rhythms have in common, dots around the dial show where each layer falls, and the moments where they meet ring out a little louder and brighter. The clearest way yet to hear, and see, two rhythms lock together.

Step out of reality and into a sample-based instrument built for the space between rooms: faded pianos, uneasy pads, room tones and half-remembered melodies. Made for liminal space, dreamcore and the particular dread of a place that's empty when it shouldn't be. Whether you're scoring analogue horror, building dreamcore loops, or just want a keyboard that sounds wrong in interesting ways, Backrooms Piano gives you a deep, atmosphere-first instrument designed around four custom effects. SOUND DESIGN, NOT JUST SAMPLES Presets are grouped into Keys, Pads, Soundscapes and Ambience, each one built to sit somewhere between familiar and not quite right. FOUR EFFECTS BUILT FOR THE GENRE LAPSE: tape-motor drift and seasick wobble, like old machinery losing its grip WEAR: ages the sound, rolling off the top end and adding instability and dust ROOM: from close and dry to a washed-out, oversized reverb DISTANCE: pulls the source away, softening the highs and revealing a filtered echo behind it FULL PERFORMANCE CONTROL A velocity-sensitive, multi-touch keyboard with octave shifting and note latch for hands-free drones and pads. Full ADSR shaping on pitched presets, so you can go from a natural attack to slow, creeping swells. BUILT FOR IPHONE AND IPAD Backrooms Piano runs as a standalone app on both iPhone and iPad, so you can explore ideas, audition presets and play live wherever you are. IMPORTANT: RECORDING REQUIRES AN AUv3 HOST The standalone app is for playing and exploring sounds. It does not record, sequence or save what you play on its own. To record your performance, sequence it, or automate parameters, you need to open Backrooms Piano as an AUv3 instrument inside a host app such as GarageBand, AUM, Cubasis, Logic Pro, or any other AUv3-compatible host. If you want to keep what you play, make sure you have a host app installed before you buy. More presets are on the way in future updates.
