$9.99

WBTRK is a complete music studio in your pocket: a fast tracker grid, 21 sound engines, a library of over 450 ready-made sounds, drum kits, a sampler, per-note effects, a twelve-channel mixer, a live performance mode, plug-in hosting and MIDI. One purchase for iPhone, iPad and Mac.
WRITE
• PHRASES of 16 steps hold notes, chords, instrument, velocity and effects; they stack into CHAINS, and chains arrange into a twelve-channel SONG
• Hold a cell and slide to set a note or a value — it plays as you go
• Select, copy and paste cell by cell, transpose whole sections, and end a note exactly where you want with OFF
• Every channel loops on its own and can run at its own tempo, locked to one clock
• A hardware keyboard on iPad and Mac, a MIDI keyboard, or any Bluetooth game controller drives the whole tracker
SOUND
• Over 450 ready-made sounds sorted by what they are — drums, bass, keys, bells, plucked, strings, winds, voice, leads, pads, fx — each one a tap away from playing, all balanced to the same loudness. Save your own for any engine
• DRUM KIT: ten drum slots in one instrument — eight built-in kits, or build your own from any sound or sample
• Classic synths: pulse, saw, triangle, FM, noise, supersaw pad, sub, pluck, wavetable and the dual-oscillator MODX, plus DRUM, an analog drum voice
• WOVEN, a macro-oscillator with 24 models and 96 classic DX7 patches; ROUND, a resonator for strings, bars and bells; MODAL for struck percussion
• SAMPLER: record or import, chop at transients, stretch to the tempo, loop, reverse, round-robin
• SPEECH sings your lyrics in English and Japanese; GRAIN turns any recording into clouds; DRONE, RESONATOR and TEXTURE build ambient beds
• AUv3 hosting: play your instrument plug-ins and insert effect plug-ins on any channel
SHAPE
• 32 effects on any note: delays, reverbs up to thirty seconds, tempo-synced gate and autopan, retrigger, chorus, flanger, ring mod, wavefold, bitcrush, slides, vibrato, arps, FOGGY granular clouds and more
• AUT automation morphs an instrument and its effect across the rows
• RANDOM dice, tables for instant arpeggios, a groove editor per instrument, scale lock
• A twelve-channel mixer with volume, pan, mute, solo and plug-in inserts
PERFORM
• LIVE MODE: launch phrases from six scenes on pads, quantized to the beat or the bar, and punch in delay and filters — or latch them
CONNECT
• MIDI in with step and live recording, MIDI out to hardware, MIDI clock and Ableton Link
KEEP
• Render to WAV (16 or 24 bit), stems and MIDI; share songs as files; your session autosaves
• A lock-screen player with cover art in your theme
• 28 themes — the studio look comes in dark and light and can follow your device — a theme editor, seven typefaces, hex numbers if you like
• English and Japanese, and a demo song to start from
Everything runs on your device. No account, no ads, no subscription, nothing collected.
