Hi,

I've been looking at these two applications for graphical notation via OSC:

ptl:
D. Henry, “PTL, a new sequencer dedicated to graphical scores,” in Proc. of the 2004 Int. Computer Music Conf, 2004, 738–41.

IanniX:
T. Coduys and G. Ferry, “IanniX aesthetical/symbolic visualisations for hypermedia composition,” in Proceedings International Conference Sound and Music Computing (SMC’04), 2004.

(what in youtube: http://www.youtube.com/watch?v=WvGFtYzJ88s)

I suppose their developers or users are on this list, so I was wondering about a couple things.

These papers are from the same year, yet I take it they are separate projects.  Has this changed at all?

How does time work in ptl?  I don't have the program, but from one of the images it looks like time flows left->right, triggering the events made by the position of shapes.

Any progress in these applications in the last 5 years, or others?

cheers,
Rich
