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.

it's more than enough to use just 'patch select'. Use MSB and LSB at page 190 and 191 of DATA List.

just use program change.
'patch select'. Use MSB and LSB at page 190 and 191 of DATA List.

If you are in edit of the patch click on patchname
and then second button from the bottom left.
it will show the three numbers to fill in.
mostly 64 then two numbers.

Make sure you decrease the last number with 0ne.
so if you see: 64-33-40 you enter 64-33-*39*
