RUBBERBAND is not a keyboard. It's an elastic surface where every line is a magnet: you glide, and GRAVITY pulls notes toward the scale. All the way up, you can't play out of tune. At zero, it's free glissando. In between, your ear decides. A microtonal synth built to be both an instant toy and a serious instrument — played like a theremin or a ribbon controller, tuned like the world. THE WORLD'S TUNINGS RUBBERBAND truly speaks microtonality — not an effect, the heart of the instrument. Arabic maqam, Turkish makam, Persian dastgah, just intonation, just blues and barbershop, klezmer modes, Southeast-Asian equiheptatonic, xenharmonic temperaments (19- and 31-TET, the harmonic series), Western scales — with region-adjustable neutral tuning. The engine thinks in cents: any tuning on Earth is within reach. 36 VOICES Plucked strings, basses, bowed instruments (violin, cello, kamancheh, sarangi), bells and bars, synth voices, the RUBBER↔STRING morph, the instruments of the East (oud, qanun, santur, ney, zurna, duduk), and granular clouds. Every voice is physically modelled and rendered in real time — no samples. EXPRESSIVE UNDER THE FINGER (MPE) Pressure is dynamics; gliding along a string changes the colour, from sul tasto to ponticello; vertical is pitch. Tilt the phone and it becomes an axis of expression. MPE MIDI out drives your other synths with the same gestures. LISTEN TO THE ROOM RUBBERBAND hears the music around you, detects the key, and tunes to it. Play along with anyone, in tune. ALSO A DRONE holding the tonic under your playing, a sympathetic halo that rings the neighbouring strings, a LOOPER to stack loops, and recording your takes straight to your device. IN YOUR LANGUAGE Full interface in English, French, Spanish, Italian, Portuguese (Brazil), German, Turkish, Japanese, Simplified Chinese, Korean and Arabic — with real musician vocabulary in each, not machine translation. Haptics, Metal rendering, fully native. No account, no ads, no data collected — the microphone is analysed locally and never recorded or sent. FREE, THEN PRO Start free: the full elastic surface, starter voices, and a taste of the world's tunings. The RUBBERBAND PRO unlock (one-time purchase) opens all 36 voices, the full catalogue of world tunings, recording and sharing, MPE MIDI output, MOTION and LISTEN. One-time purchase. No subscription.
