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

Best of its kind for endless jam sessions

I have been trying different generative apps for the iPad and this is the best I’ve tried so far. I doubt I’ll buy another since this does what I want.

It’s simple and immediately ready for use. Just press play.
It’s deep with all kinds of constraints to manipulate.
There is a nice webpage explaining how to use the features for anything I can’t immediately figure out.

Oh and one little thing I almost forgot to mention… It actually sounds interesting. These are not simple robotic arpeggios or non-musical sounding randomness. I can actually turn this on and just jam with my drum machine and guitar.

Thanks Devs. Good lookin’ out.

Amazing app, endless exploration.

I use this all the time to sequence software or hardware. It has a synth engine built in but it’s not about that. I would advise to leave it running your other gear. Had fun as soon as I installed it and I’m Still learning new things about it. Really can’t ask for more.

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.
