Just incase anyone else wants it, here is a link to the finished version of the apogee control (
http://bit.ly/f9miXd), to run it you need to download max 5.1 Runtime, (
http://www.cycling74.com/download/Max5Runtime_42462.dmg) which is the free version of maxmsp that just allows you to run max patches etc. but not edit them.
To get everything to work, setup the Trak2 in the Audio Midi Setup as you would a midi keyboard, and then load up the apogee control and select the trak2 in the drop down menu, and you are good to go. also if you do want to control it from tools then you can do it from a midi channel, with the appropriate CC messages from the manual.
It should also work on PC, though I don't know the equivalent set up for Core Midi or whatever.
