You can not access both units by one RME ASIO driver, as they use different drivers.

The Digiface USB does not support stand-alone operation, so you need to take the Digiface USB as primary interface.

You have to connect the UCX to the Digiface USB with 2 TOSLINK cables:
- towards UCX for sending audio for D/A and to transmit clock signal
- from UCX to receive audio A/D

Clock master is Digiface USB (clock source: internal), Clock Slave is UCX (clock source: ADAT).
UCX: for stand-alone operation you can load setup from 6 user and 2 factory setups.

To prepare routing for stand-alone operation you connect also the UCX by either USB or Firewire.
USB allows you to perform firmware updates as well.
If the configuration of routing has been done for the UCX then store configuration in one of the 6 user profiles.
Then you can disconnect the UCX.

How TM FX works with 2 audio interfaces.
In the upper right corner of TM FX window you have a selection box to select either UCX or Digiface USB.
Whats also possible to open a new TM FX window and to have one TM FX window for each of the recording interfaces.
If you save this to a workplace file on PC or by using the Quick Workplace Select feature then even the window placement
of the two different TM FX instances are being restored.

See manual for details what is being stored to snapshots and workplaces.
I recommend to store snapshots and workplaces to the PC into files.
Then you can recover all settings from these 2 files on every PC (if you restore from backup or copy these files to other PC).
After you have done this I suggest to use also the Quick Workspace Select feature, as then you can recall up to 30 different configuration additionally and recall setup 1..9 with ALT-1, ALT-2 ...

Thanks that you liked it

Confirmed, with some additions to make it 100% clear:

You install both drivers for operational reasons, otherwise the interfaces can not be accessed / configured by TM FX.
And you need the driver for firmware upgrades.

In the application / DAW you only use the "madiface driver" of the Digiface USB, as this is your primary interface.
The UCX will be accessed via ADAT through the primary interface (Digiface USB).

Also for Firmware updates you need the two USB driver of the two different interfaces.

At the end its only a matter of taste or number of USB ports, whether you keep the USB cable of the UCX connected or not.
The difference is
a) whether you still want to operate it quickly per TotalMix and
b) from where the UCX gets the config
    - with USB cable: from TM FX
    - without USB cable (stand-alone): from the last user profile that you reactivated

If you want to use the ARC USB, then please activate the ARC USB only for the TM FX instance of the Digiface USB.

Compatible ? In what regards ?

ADAT is a standard, its compatible.

> Is the HAMERFACE will be configurable in standalone with TM ?

There is a contradition. If the interface is in stand-alone mode, then its not connected by USB/FW/....
And if its not connected to the PC, then TM FX can not control it, because it is in stand-alone mode.

Please explain what you intend to do and what is not clear.

Please check the manual, whether stand-alone operation is supported for the multiface and how it works.

Its a simple text search in the PDF document for the word "stand-alone".

Taking a Multiface II doesnt seem to be that good, because according to manual it has no internal storage.
You need to connect it to the PC, then configure it (or maybe it loads then the previous configuration).
Then you need to set "disconnect mode" and ensure that the powersupply is plugged to it.
Then you may disconnect it physically from the PCIe card.

This sounds a little bit too complicated to me, an interface which store the last configuration or which has up to 6 user configs sounds to me much better from operational perspective.

Ideal would be an interface which has all the ports that you require.
And if you need more Mic preamps or analog channels, to expand it by MicPreamps and ADDA converter using ADAT/MADI.

Hi Ramses,

I'm trying to do the same. I use a digiface USB and a Fireface UC and three other ADAT devices. The other ADAT devices are showing up in TM of the Digiface and work fine. With the Fireface I did everything as you described.
My problem is that in the settings of the Fireface the only options for Clock Mode are:
SPDIF Coax.
Optical In
Word
LTC
Internal

There's no option for ADAT wich is what you recommended . Although besides the dropdown for Clock Source it states "Current ADAT".

The inputs of the Fireface show UFL in TM of the Digiface so there is no signal coming in.
The inputs of the other ADAT devices show fluctuating gain in Digiface TM so I assume they're working. The Input Status in the settings of Digiface In 1 - In 3 (other ADAT devices) constantly switch between Sync and Lock. In 4 (Fireface) shows Sync.

What am I doing wrong?

Thanks
Paul

Hi Ramses,

thanks for the quick answer!
There is no signal coming from the Fireface in to TM-Digiface but there is coming signal from the other ADAT devices.
Could you please have a look at my settings screenshots? The last 8 Channels in TM are the channels coming from the Fireface:

Upps I'm sorry. I merged the three screenshots.

Hi Jeff,

thank you very much for helping me!

How does this work? I'm just used to working with only one device and one TM.

Oh ok, that was a stupid question. Thanks for pointing me in the right direction.

I do all routing in the DAW. I never use TM for anything except setting the input gain of channels. I will take some time to learn the basics of TM and get back to you with more stupid questions.

Thanks

Open TotalMix FX for the Fireface UCX. Select the Phone out in the bottom row by clicking on it. Now this channel should be a brighter color than the other channels in the Hardware Output row, this means the Phones 7/8 submix is selected. On the top row, raise the fader for Hardware Input channel ADAT 7/8.

Phones 7/8 is assigned as Main Out. So start by selecting Main Out instead.
