Yup, its “in line” and not AUX… meaning that the MC goes straight into the compressor and the compressor goes into the ARmkii…you were correct the first time…
But the ARmkii has individual outs…so I can split the kick out through it’s dedicated output and feed the key input of the compressor…to just duck the MC signal when the kick from the AR needs the bottom end space…
The combined mixed signal is then compressed again using the AR master bus comp for glue …nice…
