Alvo Sequencer

Alvo Sequencer is a 16-channel step sequencer with a stable of built-in analog-modeling synths — a self-contained groovebox for iPhone and iPad that also drives your MIDI hardware and apps.

SEQUENCER • 16 channels, up to 512 steps, swing, live BPM scrubbing • Every step on screen at once: tap to add, swipe to paint, drag up or down for pitch • Record live from the built-in keyboard or a MIDI keyboard, or enter notes step by step • Mute any channel • Per-channel transpose sub-sequencer: a second sequence with its own length that transposes the first — polymeter and evolving harmony from two simple patterns

SYNTHS • Built-in analog-modeling synth engine with a full parameter editor • 50+ factory sounds across Arp, Bass, Lead, Pad, Keys and Drums — hold to hear one before you choose it • Automatic CPU load management keeps the audio glitch-free

CONNECT & RECORD • Route any channel to internal synths or CoreMIDI hardware and apps • MIDI clock sync with start/stop and BPM detection • Record your full mix and share it (Pro) • Projects auto-save; import and export project files (Pro)

The free version includes the full sequencer, 4 synths and 2 projects. One purchase unlocks everything — no subscription.
