Have you looked in the MODX Data List which gives MIDI commands ....

To change patches or programs on the Yamaha MODX via MobileSheets, you need to use SysEx messages. The general structure of the message is:
Code:
F0 43 10 4C 00 00 00 01 F7
Where F0 is the start of SysEx, 43 is the Yamaha manufacturer ID, 10 is the device ID, and 4C is the program change command. To change to a specific patch (for example, patch 5), the message would be:

Code:
F0 43 10 4C 00 00 00 05 F7
Make sure the MIDI channel in MobileSheets is set correctly.
