Many of you knows that Hans-Christoph Steiner has done an extremely interesting piece of music using pd's data structure named Solitude.
Maybe some of you don't already know that all the pd patch are available. On the technical side, it is a unique chance to understand how to use data-structures. On the musical side it is also an unique chance to compose something new from that framework.
On http://www.graphicalscores.org you'll find an interview of Hans-Christoph Steiner about Solitude where you'll learn some more interesting details about it.
There is also a Wiki, if anyone there as done some "graphical score related stuff" don't hesitate to add a reference to your work or contact me directly.
all the best, Damien.
