Drum Map attempt failed help please

[Gotta Getmedat]

I've tried to figure this out but need help.

I just need to remap note numbers from say 36 to 37 and maybe others randomly not a simple transpose.

I can't understand what 'Params' is?

I have a Note Maping (which btw is a typo there are 2 'p's in Mappings).

Channel 1 to channel 1 ideally? or 2 I've tried.

I'm assuming "Input" set to Note Number means that the input value in the equation Y= input+P1 (where p is a number 1-127 or whatever)

while the graph it is under does not correspond as it shows Velocity, while showing a range of 0.0 to 1.0?

Anyway as you can see have read the documentation in it's entirety yet nothing makes any sense to me so far.

Please how can I use this to map one note number to another note number?
