The first thing you'll want to do is learn the basics of what types of MIDI commands there are, and an overview of it's purpose: https://theproaudiofiles.com/midi-basics/

It all usually just comes down to a few basic MIDI commands for most devices - control change, program change, and system exclusive. The "Patch Command" in MobileSheets is really just a fancy way of sending multiple control changes followed by a program change. So you'll just need to look at the documentation for your MIDI devices to see what features can be controlled over MIDI, then you can set up MIDI commands in MobileSheets to trigger those features (or you can trigger actions in MobileSheets using MIDI actions by listening to certain MIDI commands from your instruments).

Thanks Mike !
I think I've got the basic history, philosophy, etc ... I'm just not familiar with how it's implemented in Mobile Sheets or anywhere else for that matter. Guess I need to experiment.
