## Description

A music studio in your pocket — write phrases, stack songs, perform them live. 15 engines, sampler, AUv3 hosting, MIDI. No ads, no accounts, everything on your device.

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.
