If you say converter, then you mean a digital connection.
So you have this setup, RME ADI-2 Pro and AKAI Force both connected through USB
PC---MADIface ASIO driver---USB2----ADI-2 Pro FS R BE
\
\---AKAI driver----------------USB2----AKAI Force
If you work with a DAW a DAW can only load one audio driver.
I assume the ADI-2 Pro FS R BE is your main interface and you will load the MADIface ASIO driver.
The USB connection to the AKAI force you will need in this case most likely only for operating the device,
not to transder audio and the USB connection can't be used for audio transfer, as the DAW can only load one audio driver.
OK .. so .. how to record audio from the AKAI force using the ADI-2 Pro FS R BE ...
PC---MADIface ASIO driver---USB2----ADI-2 Pro FS R BE
\ ^ Analog IN

\ | Analog OUT
\---AKAI driver----------------USB2----AKAI Force
And this should cause issues ?!?!?!
