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.
