That would be extremely nice, many thanks for looking into this :-)

There is maybe one additional point for DIGICheck, not sure whether possible.
To be able to visualize DURec Playback via HW Inputs in DIGIcheck without having
to route those inputs 1st to a free HW Input/Output pair of channels and using then loopback.

%-----------------------------------------
The details:

I am just playing back the recorded multitrack file with DURec, all is very nice (4 mono, 1 stereo channel).
DURec playback I am performing through the not used HW Input channels MADI 59-64
(I am doing this to be able to use a different Mix and EQ settings between DURec recording and playback).

Now I would like to see the effects of EQ adjustments while DURec playback of MA 59-62, i.e. for
1. the two Mic recordings of guitar (MA 59+60)
2. the whole Mix (MA59-62)

To 2. I got it to work by using loopback of MAIN OUT (AES).
Although I see no signal on the corresponding HW Input (AES) I can use in Totalyser the HW inputs AES L and R
to see the effects of EQ settings.

To 1. this seems to be a harder nut.
I need to route HW inputs MA 59+60 to HW Outputs MA 63+64 and then use loopback there
to be able to capture the Durec Playback of MA59+60 with DIGICheck Tools on HW Inputs MA 63+64.
So as can be seen, never too bad to have a few unused channels on an interface for such routing / loopback purposes

%-----------------------------------------

The question is simply, wouldn't it be nicer if DIGICheck tools could pickup the audio signal directly from HW Input channels instead of having to use loopback ? Maybe somehow technically possible, maybe as future extension of TM/DIGICheck ?

Here a screenshot with the routing of one MA output channel with Loopback enabled
and right beside the settings for the Totalyser, to illustrate this a little bit ..

And let me say the functionality already "just right now" is simply phantastic I am really very satisfied with it, the perfect Tape Deck Mode for me :-) And allows for all options to postprocess later with Cubase on demand.
