The software developed by ossia partly relies on specifications produced during the i-score research project, which has been led by LaBRI (with several academic, industrial and artistic partners) since the late 1990s, in order to devise new models and applications for designing and executing interactive scores, first for musical composition with Boxes, and IScore.

Intermedia and multimedia support has then been added starting from 2008 with the Virage research project, and then with the i-score sequencer.

Following the ANR OSSIA research project, which took place between 2012 and 2015, a new version of the sequencer has been implemented by Jean-Michaël Celerier, as part of his doctoral thesis. This endeavour has been joined by several artists and developers, which established itself as the ossia collective. The sequencer has been named ossia score, and its underlying library libossia. They are both available on GitHub, and documented on this very website.
