Sequentia: MIDI Sequencer

A generative MIDI brain for your synths, drum machines & modular.

Sequentia turns your iPhone into a generative MIDI brain for hardware synths, drum machines and your DAW. No built-in sounds, no clutter. Just fast, musical MIDI that plays straight to your gear over USB, Bluetooth or Wi-Fi.

Build a rack of modules that share one tempo and key: • Drums: eight lanes with curated grooves (Techno, House, Electro, DnB). Hit Random for instant, balanced patterns. • Acid: 303-style lines with slide and accent. • Chords: diatonic progressions in your project key. • Arp: arpeggiate a chord, on its own or following Chords. • Mod: LFOs that sweep a CC on your synth for movement. • Mixer: live Solo, Mute and level for any module. • Piano: play your own notes by hand, in key or chromatic.

Make it move: • Random for instant ideas, Mutate to evolve patterns over time, plus Fills, Humanize and Chop for a live feel. • Per-voice editing: swing, gate, ratchet, velocity. • Play modes: forward, reverse, ping-pong, random.

Built for hardware: • Sends notes and CC to any MIDI device. • MIDI Clock and Start/Stop to sync your gear. • A virtual "Sequentia" source to record into Logic, Ableton and other DAWs. • Per-module device and channel routing.

Save your work as projects, export to .mid, and keep your own pattern and preset libraries.

Sequentia is free. Sequentia Pro unlocks all drum styles, the full generative engine, your own libraries, unlimited projects, and studio features (send to DAW, MIDI export).
