Interactions with Music.
We design playful, spatial experiences.
From rapid prototypes to show-ready demos & production apps, we turn complex technology into things you can feel.
We believe in
- Play as a serious tool
- Bleeps, Bloops, Springs & Splines
- Discovery as a way of working
- Human-made design, no AI slop
- Add MIDI wherever possible.

How to connect iOS to MIDI for Playtonik
Playtonik is a MIDI Innovation Award winning musical fidget toy for iPhone and iPad. We built Playtonik to be fun to play with straight out of the box, with no external gear, but for those of you with hardware or software synths there's a whole other layer of fun.

Musical Physics - Lessons from building music apps in Unity
We used the Unity game engine to create Playtonik - an experimental musical instrument and fidget toy with MIDI support for iOS. We chose to use a game engine because it was the fastest place to test to the novel feature of our app: the interaction of physics objects to make sounds.
Experiments
Web instruments & utilities.
WebMIDI & WebAudio tools that keep the web musical & playful.
WebAudio / WebMIDI
Pocket Operations
Sketch patterns, send them to hardware over Web MIDI & export loops as .midi files.
WebAudio / WebMIDI
MIDIWeb-Hub
A curated directory of browser-based musical tools, utilities & WebMIDI experiments.
WebAudio / WebMIDI
Augment
An Audio UX generator for polished clicks, pops & small expressive cues built in the browser.
