How to map what MIDI launchpad buttons play what notes?

Hello! I am very new to DAWs and MIDI so I apologize if this is a simple question.

I have an old Novation launchpad mini mk1. I was able to quite easily get it connected to Ardour, however I have the issue where a lot of notes are missing, and thus can’t be played by the launchpad. Pressing the buttons from left to right does as expected make it go up by one half note per button, however when I go down to the next row it jumps 7 or so half notes forward, making the notes in that gap unreachable. I did find this manual page, however it was very confusing for me, and I’m not 100% sure if this is what I’m actually looking for, or if “mapping” refers to some other concept in music production that I am unaware of.

Although not necessary for me, I am also a bit curious about binding the circular buttons on the edges to specific functions in Ardour like playing the music, starting recording, etc, and also the ability to change how the lights work, like making all the black notes be different colors than the white notes.

If it is of any relevance, I am using Ardour on Linux using flatpak, with Ardour version 9.7.

Thanks in advance!
