I have searched the entire website for the answer and can't find anything. I have connected my Quantum 2626 to the 1818 via adat cables (both in and out) and Logic sees the channels. Clocks (2626 as ADAT an 1818 as internal) and rates (44.1) are set correctly and I get signal via the inputs on the Quantum but not from the 1818. I see all the channels in Logic Pro X but I get no signal from the 1818. Quantum is connected to my mac via Thunderbolt 3. What am I missing or misunderstanding?
