Sorry, for some reason you sounded anti FL haha
And anyway, no daw supports non native feedback, ableton only has feedback for the mixer and for racks, and a rack won't receive from a vst or any linked plugin, neither is there feedback for manual linking.
And I wanted relative because if they were set to absolute they would be internally absolute, so when I highlight a separate plugin the params would jump to what the encoder was last set to, even in makie mode.
Also the BCR2000 will receive feedback, but only after you change page, same thing for Livid stuff, APC and anything else set to its own port.
Also there is midi pass through, but the setup is weird, its to allow maximum flexibility, you link the CC per plugin to whatever input CC you want, so I have Massive set up to receive CCs 21-28 from my Launchkey but also CCs 400 and something from my APC, this is only possible by doing the weird linking stuff. You could also patch the midi port directly into the plugin with patcher, which is easier I guess... haha
