Controlling multiple keyboards with the MC6

I’m very new to the whole midi contol world and just ordered an MC6 recently to control my keyboards as I tour this year.
I have a Nord Electro 5, and and Korg’s Minilogue XD and Prologue.
All the presets on these boards have values higher than 127 and I wanted to know how I could access the higher numbers, as all the sounds I need access to are in the higher ranges.

I’m looking to send multiple messages in one bank where I’d change all three board sounds at the same time as I go from song to song.

If anyone knows anything about how to access the presets on any of these boards, I’d greatly appreciate it!
