I need advise on connecting analog hardware to an RME setup using the items listed below.

AUDIO INTERFACE - HDSPE MADI FX (TOTAL MIXFX V1.5)(MADI CABLE DUPLEX)
AD/DA - RME ADI8-QS (MADI OPTION INSTALLED)(MADI CABLE DUPLEX)
OUTBOARD HARDWARE - DUAL MONO (ANALOG COMPRESSOR)(XLR TO TRS CABLE)

Basically I want to connect the outboard comp to the analog I/O of the adi8-qs, and use the routing capabilities of total mix, to access the hardware, (Example : Mic Input via trs line in on the adi8-qs, using the comp), no DAW software required.....

I have looked at the hardware version of this same concept, (Dangerous Music Liaison), but I would rather use total mix to achieve the same result, if it's possible.

I plan to add more outboard hardware in the future, but I need to grasp the concept first.

Any guidance from the totalmix experts would be greatly appreciated........... Thank You......... Brian Edwards
