That's interesting - any reason you use ADAT instead of USB? As I understand it, USB gives you 16in/out.
Yes, USB will give you 16 in/out - when you use the USB connection to connect the h9000 as an
audio interface to your DAW computer. It is
not the case that the h9000 will connect via USB to your DAW machine, and those 16 i/o then appear alongside whatever other audio interface you have set up for your DAW (unless you use MacOS "Aggregate Audio Interface" function in CoreAudio). It is also
not the case that the USB connection will somehow stream audio from a plugin instantiation of eMote to the h9000 and back.
Unless you're using Aggregate Interfaces / Dante / or PT Interface emulation, all audio routing to / from the h9000 must be done via your primary audio interface and whatever facilities it has. If you have a Focusrite Scarlet 2x2 interface then you ain't connectin' nothin'.
Since I have a MOTU 112d + 1248 setup, I have tons of ADAT ports sitting unused, and it's quick to grab a pair of Toslink cables and set up an ADAT port as four stereo pairs to + from the h9000.
That said, when connected to the DAW machine via USB, the h9000
can function as an audio interface, either as a part of an Aggregate Interface, or as the
only audio interface on the DAW machine - that's when the 16 i/o might be useful. Although it would perhaps be less than elegant, you could connect the h9000 to the DAW via USB, then connect speakers (up to 7.1) to any analog or digital outputs on the h9000, plug mic preamps etc. to the analog inputs, stick a few digital devices to the AES + S/PDIF + ADAT ports, and use the h9000's internal routing to get all the signals going where they want to go. It is truly nuts.
Each of the expansion card slots, which can hold Dante, MADI, and PT HDX Interface Emulation cards, can access 32 channels EACH, for a grand total of 128 channels of i/o (32 on each slot plus 32 on the back panel). BUT. Each of the four DSP engines can only access 32 channels at a time. Exactly what other restrictions may exist in a fully bricked-out unit are a mystery to me since I have no expansion cards installed.
It's really difficult to find good information about these! I spoke to a LA-based 'expert' ("Nobody knows this unit better than me" etc) yesterday about the internal series FX Chain routing and his vague answer was "Hey man, there's
nothing this box cant do!"
I think the LA-based expert is smoking the good shit. The issue about routing FX Chains into each other in series internally still exists, according to the FAQs on the Eventide site:

A:
You currently cannot route the output of one FX Chain into the input of another FX Chain. We are planning on adding this as a feature in a future update.

A:
The current software release does not provide for mixing the outputs of FX Chains. As a result, two or more FX Chain outputs cannot be combined internally. You’d have to route the outputs to an external mixer. We are considering adding mixing functionality in a future release but that project is not scheduled.
So.... yeaaahhhh NO. Not currently. That is why I was just configuring the unit as four stereo i/o inserts, one for each FX Chain, and routing + mixing in the DAW. That's also why a single ADAT port is fine for me at the moment, since that's four stereo i/o pairs and is a neat match for the current configuration of the machine.
