Hi roboldham,
have a look at the Midi Control Center -
https://www.arturia.com/support/updates&manuals#mccu-1368980017You connect your drumbrute via USB (best way is directly to machine, no hub). The MIDI Control Center recognizes a connected Drumbrute. Skip all the updating business for now, you can do that later (as for some there seems to be troubleshooting involved).
On the left hand, below the dropdown where you pick your device and drumbrute should now be set, there's a list with two items, "blank" and "default". Select "default" and click "Store to (arrow up)" - "blank" wipes all patterns so they are empty, "default" uploads the default patterns.
You should be set!
Note: The sounds of each instrument are controlled with the pots directly wired into the analog circuit (like in an 808). You can restore the notes (sequence) being played but not the sound of an indivdual instrument - for that, use the knobs.
In this thread you can find some more patterns provided by user terrym -
