Typical RTL of different RME solutions, see here in my blog in this article:

So you want to sell the old stuff and base everything on RME or only the recording interface ?
Do you need a PCIe based solution or doesn't it matter whether to choose an USB/TB or PCIe based solution ?

What is your budget ?

Hi all,

Apologies for the noobish questions in my first post here.  I'd like to rehaul my recording setup into something actually proper, after reaching the limit of my patience with OSX-clocked aggregate audio devices and other terrible ideas like that.  Digiface USB looks like it could enable this rehaul quite well, but I just want to make sure I'm planning this correctly before I drop 800 EUR on this plus a couple of ADAT interfaces.

I'd prefer to be able to record from 18-22 analog inputs, and route audio to 12-16 analog outputs (in addition to a main mix and headphone mix).  I have a MOTU Ultralite Mk4 that has ADAT in + ADAT out + 6 analog inputs + 8 analog outputs (besides main and headphones), and I'm considering buying two Behringer ADA8200s which each have ADAT ins + 8 analog inputs + 8 analog outputs.

Here's how I imagine the setup, where Digiface is the clock master over all the other interfaces (via its ADAT outputs):

Digiface outputs:
- Digiface ADAT output 1 => Ultralite ADAT input, which syncs the Ultralite and sends it up to 8 channels of audio
- Digiface ADAT output 2 => ADA8200 #1 ADAT input, which syncs ADA8200 #1 and sends it up to 8 more channels of audio
- Digiface ADAT output 3 => ADA8200 #2 ADAT input, which syncs ADA8200 #2 (and I wouldn't need to send this audio)
- Digiface ADAT output 4 => Expert Sleepers ES-3 (Eurorack module for DC-coupled output) ADAT input, which syncs the ES-3 and sends it up to 8 more channels of audio

Digiface inputs:
- Digiface ADAT input 1 <= Ultralite ADAT output, which sends 6 channels of audio to the Digiface
- Digiface ADAT input 2 <= ADA8200 #1 ADAT output, which sends up to 8 more channels of audio to the Digiface
- Digiface ADAT input 3 <= ADA8200 #2 ADAT output, which sends up to 8 more channels of audio to the Digiface

Would this work in terms of routing and synchronization?  And when I record, the Digiface USB would be the only audio device I interact with in the DAW, right?

By migrating into this setup away from my failed experiment of an aggregated Zoom L-20 + MOTU Ultralite Mk4, I would be giving up standalone (without a host computer connected) monitoring, but I'm hoping that this setup would minimize my roundtrip latency (I like to monitor my DAW, and I also send timing-critical clock and CV signals out of my audio interface) and have no inter-device synchronization issues like the ones I've struggled with when aggregating audio interfaces through OSX Audio MIDI Setup.

Thanks all.

Do I also understand correctly that, in order to monitor with the Digiface USB, all you need to do is also power-on the computer that the Digiface is connected to (and that has the required drivers installed)?  You don't need to launch the TotalMix app, or a DAW, unless you want to control levels, right?  If so, that wouldn't be too steep of a workflow adjustment for me.
