WBTRK

Host AUv3 synths, chop samples, drive hardware over MIDI — and make it sing with real lyrics. A full groovebox: one price, no subscription, all on your device.

WBTRK is a music tracker in the classic mold — rows, steps and patterns — rebuilt for iPhone and iPad with a sample-accurate audio engine. And now it sings.

Write PHRASES (16 steps of notes, chords, instruments and effects), stack them into CHAINS, and arrange chains into a six-channel SONG. Loop a channel independently with STP/JMP markers, re-root a phrase per bar with chain transpose, and let each channel run at its own tempo while staying locked to one clock.

SOUND — 15 engines • The chip classics: 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 • SPEECH: a talking, singing robot. Build words from classic speech-chip sounds or just type them how they sound. TALK mode speaks them from the keyboard; SING mode turns a phrase into a lyric sheet — one note column picks the word, the next carries the melody, and a held syllable bends across notes like a real singer • GRAIN: a granular cloud over any recording — grain size, density, spray, scan speed and per-grain pitch, from frozen drones to Geiger-counter glitch • MODAL: struck-resonator percussion — marimba, vibraphone, kalimba, glass and church bells, steel pan — with structure, brightness, ring time and strike position • SAMPLER: record from the mic or import audio; trim, normalize, loop, ping-pong, reverse — or beat-chop at transients and play slices across the keyboard • AUv3 HOSTING: play your installed instrument plug-ins from the sequencer, per instrument

SHAPE IT • 28 effects per note: delay, reverb, trance gate and autopan with tempo sync, retrigger, chorus, flanger, ring mod, wavefold, bitcrush, slides, vibrato, arps and more • RANDOM dice that re-roll pitch, volume, envelope and pan on every hit • Tables: looping per-note programs for instant arpeggios and tremolos • Per-instrument swing and scale lock, full mixer with per-channel volume, pan, mute and solo

FAST TO PLAY • The radial wheel: long-press any cell and rotate to dial in notes, chords, instruments or effects — it previews as you turn • Double-tap places your last note or chord; select, copy, paste and transpose whole sections • MIDI in (play and record, step or live), MIDI out and MIDI clock for hardware

KEEP IT • Render your song to WAV, share songs as files, your session autosaves • A lock-screen player with cover art drawn in your current theme (and a switch to turn it off) • 26 themes plus a full theme editor — and a hex numbers mode, the way trackers used to count • A built-in demo song that sings about itself
