The INScore project is also cross-platform (Linux, MacOS, Windows).
Controlled using OSC, build over the Guido Engine, it extends the music
score to arbitrary graphic objets and gives a temporal dimension to all
of them. It provides graphic synchronization between the components,
interaction features... More about the system capabilities :

these examples are quite nice, haven't seen them in max before. I didn't look at the max folder before. if you want, I can program them in Pd, including the ones that you didn't include, like interlude.maxpat (or someone else can as well, if they want to).
I didn't see the interaction example in your folders, can you include it as well?
What is the current situation of this project? Are you temporarily at Grame, is this a thesis of yours? How long is it going to be developed, are there going to be any license issues in the future, etc etc.?
