Wow, thanks sovietpop! I’ll have to look more into that.
I’ve been looking at a similar setup, but was eyeing the Mackie Onyx 1640i, which from initial glance at the photos, has a simlar I/O section to the 16.4.2.
I’d like a mixer (and not an audio interface), so I can both record, but also use a tactile mixer’s aux routing to push whatever sound I want into the Octatrack, so I can sample live, but still have the other machines running on their own. Along with something like the Cymatic Audio LR16 plugged into the D-sub connectors, you could record all your tracks individually and then mix later if you wish.
