I've written a helper patch that sends and receives OSC data between the TouchOSC program (on the iPhone) and Max/MSP.

This one works with the Mix16 Layout.

I'm using TouchOSC 1.5 and Max 5.0.5. on a MacBookPro and the OSC stuff "Everything For Mac OSX" from CNMAT. http://cnmat.berkeley.edu/downloads

Here is the link to the my max5 patch: http://home.lagrange.edu/mturner/software/mix16_send-and-receive.zip

Hope others find it useful, Mitch
