It is unclear, but it looks like the M13 cannot send midi PC commands. I just wanted to confirm if this is true.
Can The M13 Send Midi Program Changes?

It does send program change messages when you select a scene, but its MIDI map cannot be changed. The PC messages it sends are the ones that are associated with the 48 scenes.

So am I correct in thinking, scene 1 will send PC #1 & so forth up to #48?
Mostly correct... It uses PC #0 - 47 for the scenes.
There's a table on page A.2 of the Advanced Guide that says what PC#s are associated with what scenes.
