[**ossia score**](https://ossia.io) is a ***sequencer*** for audio-visual artists, designed to create ***interactive*** shows.

Sequence **OSC, MIDI, DMX, sound, video** and more, between multiple software and hardware. Create ***interactive*** and ***intermedia*** scores, ***script*** and ***live-code*** with JavaScript, [ISF Shaders](https://isf.video), [Faust](https://faust.grame.fr), PureData or C++. Leverage IoT protocols such as CoAP or MQTT, interact with joysticks, Wiimotes, Leapmotions, Web APIs and BLE sensors and integrate programs from a wealth of creative programming languages such as [Structure Synth](https://structuresynth.sourceforge.net/), [Context-Free Art](https://www.contextfreeart.org/) and [Bytebeat](https://dollchan.net/bytebeat/). Load any kind of audio or video format and process visuals through Spout, Syphon, NDI, Shmdata or Sh4lt ; sonify large datasets with CSV and HDF5 support.

Free, open source and runs on desktop, mobile, web and embedded, down to Raspberry Pi Zero 2.

## Contributing

When updating the score repository through the command line, don't forget to update the submodules, they change often.

    cd score

    git pull

    git submodule update --init --recursive

Some useful and easy potential contributions are listed [on the website](https://ossia.io/project.html).

There are also many fixable areas in the code :

* [**TODO**](https://github.com/ossia/score/search?q=TODO) : for simple issues.

* [**FIXME**](https://github.com/ossia/score/search?q=FIXME) : for critical bugs / problems.

* [**MOVEME**](https://github.com/ossia/score/search?q=MOVEME) : when something is not where it should be.

* [**REMOVEME**](https://github.com/ossia/score/search?q=REMOVEME) : when something is redundant.

* [**RENAMEME**](https://github.com/ossia/score/search?q=RENAMEME) : when the class does not match with the file it's in.

* [**OPTIMIZEME**](https://github.com/ossia/score/search?q=OPTIMIZEME) : when an easy-to-write-but-suboptimal algorithm is used.

Finally, one can write its own score plug-ins to add custom features to the software.

An example plug-in with the most common classes reimplemented is provided [here](https://github.com/ossia/score-addon-tutorial).
