WBTRK is a complete music studio that fits in your pocket — 18 instruments, a sampler, per-note effects, a full mixer, plug-in hosting and MIDI, wrapped in a fast grid workflow that lets you write whole tracks with your thumbs. WRITE • Compose in a grid: 16-step PHRASES stack into CHAINS, chains arrange into a six-channel SONG — the fastest way to sketch on a phone, deep enough to finish • The radial wheel: long-press any cell and rotate to dial in notes, chords, instruments or effects — it previews as you turn • A chord picker with real harmony — maj7, min7, sus, dim — plus select, copy, paste and transpose for whole sections • Loop channels independently, re-root phrases per bar, and let every channel run at its own tempo while staying locked to one clock SOUND — 18 instruments • Classic synths: pulse, saw, triangle, FM, noise, supersaw pad, sub, pluck, wavetable (draw your own cycle), and MODX — a dual-oscillator synth with a 4-LFO modulation matrix • SAMPLER: record from the mic or import audio; trim, normalize, loop, ping-pong, reverse — or beat-chop at transients and play the slices across the keyboard • A singing robot voice with real lyrics, granular clouds over any recording, and struck modal percussion — marimba, bells, steel pan • An ambient section: DRONE, RESONATOR and TEXTURE — beds, drones and weather • AUv3 HOSTING: play your installed instrument plug-ins from the sequencer, and insert effect plug-ins on any channel SHAPE • 29 effects on any note: delay, two reverbs (one runs to thirty seconds), tempo-synced trance gate and autopan, retrigger, chorus, flanger, ring mod, wavefold, bitcrush, slides, vibrato, arps and more • True stereo instruments — place every oscillator in the field • A full mixer: per-channel volume, pan, mute, solo and plug-in inserts • RANDOM dice that re-roll a note on every hit, tables for instant arpeggios, per-instrument swing and scale lock CONNECT • MIDI in (play and record, step or live), MIDI out and MIDI clock for hardware • Ableton Link keeps you in time with other apps and gear KEEP • Render your track to WAV, share songs as files, your session autosaves • A lock-screen player with cover art drawn in your theme • 27 themes plus a full theme editor — from the clean studio default to full retro, hex numbers included • A built-in demo song that shows the whole studio off Everything runs on your device. No account, no ads, no subscription, nothing collected.

Features
Read full description

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.
