Phase Seq app icon

Four voices. One sequencer.

Phase Seq keeps drums, bass, rhythm and lead in one focused instrument. Each voice has its own synthesis controls while sharing the same scene-based composition system.

Drums

Eight synthesized percussion voices with hands-on tone shaping and pattern control.

Bass

A dedicated low-register synthesizer ranging from clean weight to aggressive movement.

Rhythm

A mid-register synth voice for pulses, harmonic motion, chords and texture.

Lead

A higher-register synthesizer built for melodic contrast, expression and evolving tone.

Designed for fast composition.

Multi-playhead sequencing

Layer independent playheads across the grid to create interlocking rhythms and melodic movement without building every variation by hand.

Eight-scene songs

Turn a pattern into an arrangement, chain scenes, mutate ideas and keep the transport moving continuously through the song.

Record the result

Capture the app's master output directly to AAC or WAV and send the finished recording through the standard iOS share sheet.
