I’ve been trying to Rewire Renoise into Ableton to use the functionalities of Ableton alongside the tracker style. For some reason, even though I’m opening Ableton first, waiting and then opening Renoise, it asks for the password for the Mac profile to enable rewire but it never goes into rewire mode.
The development of Rewire has been discontinued, so I doubt that you`ll get it to work on modern systems and apps.
That’s why Ableton Live uses Ableton Link now.
Use the MacOS built-in IAC MIDI Bus + Virtual Audio routing such as Blackhole as Rewire replacement.
