Ableton Forum

Wow I've had 7 hours on live 12
It's a huge winner
Please Ableton can we have some more looks.
I'm using darker mode but the others are ugly lmao.
I've no other choices
The others make me feel it's not Ableton if that makes sense.
The darker modes look better but it's preference I know.
Thanks again for your great work
I will worship 12

do a search for 'Ableton themes'. you'll find lots of places to download all sorts of options, and I think most have instructions on where to drop the theme files so they appear in the selection.
