## What is Phase Seq?

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, harmony controls, and alternate playhead behaviors make it easy to explore variations without losing the core idea.
Each instrument has its own dedicated sound engine with hands-on controls for shaping tone, movement, envelopes, filtering, modulation, and character. Phase Seq is designed to move quickly, but the synth engines are deep enough to build and save your own sounds.
Features include:
• Four integrated sound engines: Drums, Bass, Rhythm, and Lead
• Multiple independent sequencer playheads
• Forward, reverse, alternate, and variable-rate playback
• Probability and pattern mutation
• Eight scenes with scene chaining
• Song-building tools
• Harmony and chord controls
• Deep synth and drum sound design
• Patch randomization with SEQ, DUB, and HEX behaviors
• Save and load songs or individual instrument presets
• Audio recording and export
• Portrait interface designed for iPhone
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.
