I just moved to an M series Mac and need a replacement for SoundFlower
I need to be able to use that driver in Cubase as well.
Check out Rogue Amoeba, they have some pretty neat tools for OS-wide audio routing.
One word of warning though: I am using their Loopback app to screen-record my DAW sessions from time to time. Enabling a virtual output can have an impact on your latency - so keep that in mind. Always turn your virtual outputs off when you’re not using them
