Hi there! if you want to continue using. touchable pro.
install Live 11.0.12 (you can install multiple versions of live on your computer) download link here : Log in or create an account | Ableton
go to settings. and turn off automatic updates!
Now start your new projects in ableton 11.0.12 and use touchable like before.
unfortunately: you can not merge new projects to older versions anymore. so you need to start your new projects in the old Live 11. To continue to use Touchable like before.
