@liamorourke That's right.
I just tested your grid on my phone and it works.
The [pdwrapper] is just for testing the patch with the editor while you are developing it...... so it is not required when you upload the patch [grid] to Android.
So the messages to format can also be dropped from [grid] once you have completely finished the development and are happy with your patch.

BUT it looks like Mobmuplat might be designed to talk over a network at the same time to Pd on another device...... your computer?
If that is the case the wrapper would still be needed on the computer and the right hand side of the wrapper might need some modification.
I have a lot of reading to do.
I cannot get the wrapper to open the broadcast socket and talk to my phone yet...... probably a setting in my home routers will need to be changed.......
