Hi!
Here is a quick and dirty example on this.
Polyphony in QC is managed by Iterators. Here’s a tut by C.Wright from Kineme.net (http://vimeo.com/808373)
I found a problem to pass the OSC data to the Iterator because the objects position is sent consecutively. For manage that I created a little max patch to extract every element and send all of them in parallel. Because of that the patch does not change dynamically to the number of circles but should work fine with any script with 20 elements.
Would be great to have an option in Iannix for sending the messages as packages in order to convert them into structures inside QC.
For running the example one will need qcOSC from http://hexler.net and Structure Tools from http://Kineme.net plugins for QC installed. And for the Max patch it is necessary the OpenSoundControl object by CNMAT (http://cnmat.berkeley.edu)
Hope is useful for somebody
