PolyPhase is a generative sequencer! Melodies on a Master Track are created on the fly & copied, with phase offsets, to Follower Tracks. This structure, along with the interplay of various probabilities, leads to interwoven melodies and rhythms. You can disable the generation of notes & draw your own, or select some of the randomization functions Send MIDI to external hardware, other iOS instruments, or use the included wavetable synthesizer! - 8 independent Sequencers with their own rate, direction, transposition & other properties - Disable the generation of notes to draw your own, or use some of the intelligent functions provided - Random Euclid & Drum Sequences - The Wavetable Synth + FX lets you use PolyPhase even if you don't own any external Instruments - Filter notes to a Global Key / Scale and toggle Chord Masks - Save / Load Presets - Snapshots for install recall of your Sequences - Intelligently Randomize and Morph your Sequences & Synth sounds - Accepts external MIDI clock & can provide clock to other devices - Audiobus (Audio / State) & Inter-App Audio support - Link Support
