Phase Seq

Start with a few notes. Add independent playheads and hear your music evolve. Shape beats and synths with an intuitive sequencer for iPhone, iPad, and AUv3.

Phase Seq is a hands-on electronic music instrument built around a simple idea: a few notes and multiple independent playheads can create surprisingly complex, evolving music.

Start with a simple pattern, then send playheads through it at different speeds, directions, pitches, and divisions. Hear rhythms shift, melodies intertwine, and unexpected musical ideas emerge — without having to program every variation yourself.

The sequencer is the instrument.

Phase Seq makes complex sequencing immediate and enjoyable. Add or change playheads while the music runs, introduce probability, experiment with different patterns, and discover combinations you might never have programmed deliberately.

Four built-in sound engines — Drums, Bass, Rhythm, and Lead — let you create complete electronic pieces without connecting additional instruments. Shape everything from deep bass and punchy percussion to thick chords, aggressive leads, and atmospheric textures.

From patterns to complete songs

Develop ideas across eight scenes, chain them into arrangements, and use PH SCENES automation to change playhead behavior as your music progresses. Scene-specific settings, pattern mutation, harmony controls, and SEQ, DUB, and HEX generation modes offer new ways to explore and develop your music.

Sound design and effects

Each instrument features dedicated synthesis and sound-shaping controls. Explore oscillators, filters, modulation, envelopes, and distortion, then add depth and movement with four stereo effects: Chorus, Phaser, Delay, and Reverb. Individual effect sends and mixer drive give you further control over the sound.

Made for exploration

Phase Seq is designed for musicians who enjoy experimenting with rhythm, repetition, and evolving sound. Whether you're building hypnotic techno, dub, ambient music, or something entirely your own, it gives you a fast, playful way to turn simple ideas into intricate musical arrangements.

The best ideas are often the ones you didn't plan.
