The akaRemote app is sending in Open Sound Control messages on port 5600 (or another one if the user selects).

These come in the format /event and then a big list about the event. You can get the exact format by looking at the patcher "p message2pvar" in aka.iphone2.1.  Essentially, I'm routing data from the first slider on the first page, rescaling it to appropriate MIDI values, and then sending that as a continuous control MIDI message.  I've commented up the patch a bit:

#P window setfont "Sans Serif" 9.;
#P window linecount 1;
#P comment 147 477 172 196617 This outputs MIDI control messages.;
#P window linecount 2;
#P comment 182 279 299 196617 This remaps the slider range from 0.-1. to 0-127 \, which is the appropriate range for MIDI;
#P window linecount 1;
#P comment 127 253 299 196617 Behold! The slider value;
#P comment 138 228 299 196617 This the third item of the remaining list \, with is the slider value;
#P comment 142 210 273 196617 This routes events for the first slider \, which is item # 10;
#P comment 103 162 273 196617 This strips off the device ID and passes the rest of the list;
#P comment 121 140 238 196617 This strips the work "/event" from the message;
