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

Dat App? ,

very cool app

Love the level of control, but also you can sit back and let it produce a great melody. Well engineered.

My one request is to be able to record to a MIDI file & save it to the ipad. Maybe it exists but I could not figure it out.

Love it but......

Great midi generator with lots of bells and whistles. It’s a bit difficult to set up in AUM as the slave! I’ve read the instructions quite a few times. Yet I was unable to set up the generator to the master tempo of AUM. Also, there’s no Ableton link support natively making it a task to sync record midi. Yes, there’s other ways to do it but make it native. Otherwise, this is amazing.

Developer Response ,

Turn off "Clock Generation" in PolyPhase, but make sure PolyPhase is chosen for Clock Receive. In AUM, Enable MIDI Clock Send and select PolyPhase. Now, PolyPhase will be slaved to AUM's tempo and respond to its transport.

Loving the possibilities!

Been feeding this through AUM to four separate synths! Great job dev!
