v0.2 of the np_epoc external for Max/MSP and Pd has been released.
VID/PID and key are now selectable by users. Users can also get a device count to make sure the VID/PID pair is set up correctly.
Hopefully key and ID detection will be done by emokit soon, but that's going to take a little more work since we're not yet sure how the key is deduced on connection.
Binaries are available on the sourceforge NP Labs release site.
