Built with AudioKit: Create New Musical Sequences with PolyPhase


PolyPhase is a new generative sequencer, proudly built with AudioKit by Marcos Kohler.

How does it work? Multiple melodies can be created from a master track (created dynamically by the app, or drawn in). Then several new tracks are generated from the master track – resulting in new creative possibilities. Thanks to the interplay of various probabilities, it’s never the same twice.

PolyPhase creates unique melodies and rhythms. Perfect for new creative options for your music.

Developer Marcos Kohler shared his motivation with us, “I wanted to create an inspirational tool that could generate interesting melodies and rhythms. While composing, I often get caught up in the details or let my muscle memory take over. PolyPhase was an attempt to break that cycle and embrace the happy accidents.”

Marcos explained his app creation process, “My initial plan was to make PolyPhase a MIDI sequencer only. Audio DSP in iOS was something I had always avoided. However, having a built in synthesizer greatly expands the usefulness of the app. It allows users to explore ideas immediately. ”

“AudioKit was extremely simple to work with” – Marcos Kohler

“Integrating AudioKit into my Objective-C project was straight forward. I made a few edits to the source in order to implement my wavetable synth, but everything else is made with the built-in components.”, Marcos remarked.

Marcos explained, “AudioKit also takes care of IAA functionality, and I used the team’s tutorial to integrate it with Audiobus.”
