Custom Zoom 223 Map For M-Audio Oxygen 8?

[Controller_C]

Hello Again KVR Forum!!!
I haven't posted here in years but not deliberately. I miss this place. Now I've acquired some used gear & was wondering how to make keyboard drum maps for the Oxygen 8- kinda like the ones IK came out with for Sampletank a while back- like 2 snares side by side on the keyboard for a two finger drum fill & that sort of thing. Is my age showing?
How do I do this for a drum sound module (hardware Not a VST instrument )?
Can I make a map for Oxygen 8 while it's connected to a DAW pc then have it saved for later use with hardware sound module?
A little off topic: could I power the Oxygen 8 with the usb printer cable connected to a lithium powerbank? Anyone try that? Might be slick- or not.
