map file place

Where does the *.map file should be located ?
i’ve tried in my .config/ardour3/ and in my root session folder, but nothing seems to work.
In addition, where, on the website, could I share my keymap once i’ve done ? I’m actually using a M-Audio Oxygen 88 controller.

answering to myself and according to this :

midi maps should be in ~/.config/ardour3/midi_maps/

i doesn’t work for me, but perhaps it will help.
