What i-score is : 7 / 20 ▶ A visual programming language → Conditions, loops, structuring, in a timeline ▶ Free software : GPL v3 (UI) & LGPL v2.1 (Engine) ▶ Built in C++ (Qt, CMake) ▶ Available on Linux / OS X / Windows ▶ Alpha-quality ☹

Hierarchy Scenarios can be nested arbitrarily 20 / 20

WIP : Spatial automations for instance. performs actions according to the result of such computations. 21 / 20 ▶ 3d splines that uses VTK. Can be used to create paths in space ▶ Spatial mappings to compute collisions, distances, etc. and

Future : distribution ? at the editing stage. 22 / 20 ▶ Currently : multiple instances can work together ▶ In progress : distributed execution. ▶ Example scenarios : ▶ 100 phones controlling a parameter together. ▶ Live backups if a computer dies during performance. ▶ Offloading due to performance requirements.

Future : other features Currently : execution can be followed via a web page. 23 / 20 ▶ MIDI , WebSockets support ▶ Some level of patching , like Pd ▶ Complete remote-control abilities. ▶ Port execution engine to FPGA . ▶ Audio engine ?

Contributing OSSIA API WebAssembly. 24 / 20 ▶ UX , UI (mock-ups were done but not entirely implemented) ▶ Documentation , writing demo scenarios ▶ Translations ▶ Implement the Minuit protocol in your software with the ▶ Many ”low-hanging fruit” TODOs ▶ Mobile devices ports : ▶ Android : builds and run but requires adapted UI. ▶ Web port : with PNaCl, runs but crashes. Will open the way to ▶ iDevices (many artists use them).
