Phase Seq

Polyrhythmic Music Sequencer

$6.99 · Designed for iPad. Not verified for macOS.

Now with iPad and AUv3 support, four stereo effects, and playhead scene automation. Build evolving rhythms, sculpt powerful sounds, and turn patterns into songs. Phase Seq is a fast, hands-on music sequencer built around multiple independent playheads, deep sound design, and rapid song building. Create patterns with Drums, Bass, Rhythm, and Lead, then send multiple playheads through the sequence at different rates, directions, pitches, and divisions. Simple patterns can quickly turn into shifting polyrhythms, evolving melodies, and arrangements that would be tedious to program in a conventional step sequencer. Build an idea in Scene 1, develop it across eight scenes, and chain those scenes into a complete track. Probability, pattern mutation, patch generation, and harmony controls make it easy to explore variations without losing the core idea. Take arrangements further with scene-specific playhead settings and PH SCENES automation. Give each scene its own rhythmic behavior, recall saved playhead configurations, or cycle through evolving playhead variations as your song progresses. Each instrument has its own dedicated sound engine with hands-on controls for shaping tone, movement, envelopes, filtering, modulation, and character. Push sounds further with mixer drive and four stereo effects: Chorus, Phaser, Delay, and Reverb. Independent effect sends let you build everything from subtle movement to dense, atmospheric soundscapes. Phase Seq works as a standalone instrument or as an AUv3 plugin in compatible iOS music hosts, with interfaces designed for both iPhone and iPad. **Features include:** - Four integrated sound engines: Drums, Bass, Rhythm, and Lead - Multiple independent sequencer playheads - Forward, reverse, alternate, and variable-rate playback - Global and per-scene playhead settings - PH SCENES automation with scene-based and cycle-based playback - Eight scenes with scene chaining - Probability and pattern mutation - Song-building tools and harmony controls - Deep synth and drum sound design - Patch randomization with SEQ, DUB, and HEX behaviors - Four stereo effects with individual instrument sends - Mixer drive and stereo sound processing - Save and load songs or individual instrument presets - Audio recording and export - Standalone and AUv3 operation - Portrait interfaces for iPhone and iPad Phase Seq is made for quickly finding ideas you probably wouldn't have programmed on purpose — then giving you enough control to turn them into finished music.
