I am still on live 9. however thinking about a new Mac (with a new version of Live, because Live 9 will work on the new device).
I red the glorious Rewire will not work anymore.
Any Suggestions for syncing Live11/12 and Renoise?
Rewire has been on the way out since 2020 when the developer stopped supporting it. Many popular DAWs have since dropped it, ie. Cubase, FL Studio, Studio one, Live.
Ableton have an article regarding alternatives to Rewire, maybe you can find something useful there?
