Here is the initial beta version of my native-C Art-Net objects, for transmitting and receiving Art-Net DMX data in Max.
There's a few features still to add, but I'd appreciate some testing feedback from people using different hardware. Please don't use these objects for high-risk stuff like performances yet (unless you're really desperate). Any features suggestions or changes are welcome.
OS X only at the moment, but eventually there will be a Windows version, I just haven't set up a development environment for building objects in Windows yet.
Feedback to firstname.lastname@example.org (or post here).
