## Description

A bio-reactive membrane you play with your fingers. Morphing oscillators, six voices, an arpeggiator and a live FX rack. 31 scales so you never hit a wrong note.

MBR-01 is an expressive polyphonic synthesizer you play by touch. No keys, no menus to get lost in — just a living surface that responds to where and how you press.

Slide across the XY pad to bend pitch and open the filter at once. The instrument is locked to the scale you choose, so every note lands in key: explore freely without ever playing a wrong note.

SIX VOICES, ONE EXPRESSIVE SURFACE • 6-voice polyphony with glide • Morphing oscillator (sine → triangle → saw → square) plus a sub • Resonant ladder filter with its own range control • Full ADSR envelope

ARPEGGIATOR • Up, Down, Up/Down and Random modes • Tempo with tap, adjustable divisions and octave range • Hold to let chords ring

LIVE FX RACK • Drive, bitcrusher, ring modulator, pitch shifter, phaser and chorus • Delay, reverb and glide for space and movement • Toggle and tweak everything while you play

31 SCALES From major and minor to whole tone, diminished and blues — through Hirajoshi, Iwato, Kumoi, Pelog, Bhairav, Marwa and more. Set the root and octave range and the whole surface re-tunes.

PRESETS A curated library across Bass, Leads, Plucks, Pads and FX — plus save your own. Each preset carries its own reactive visual style.

REACTIVE VISUALS A Metal-powered visualizer reacts to your playing in real time, with external display output for performance and visuals.

MIDI OUT Send what you play to hardware synths or other apps over Core MIDI, with channel selection.

BILINGUAL Full English and Spanish, switchable inside the app at any time.

Built for iPad and iPhone. No account, no data collection — just sound.
