Topic: Aggregating HDSPe MADI FX with a MADIface USB on Mac

I'm interested to know if anyone has tried Aggregating on a Mac an HDSPe MADI FX (running via Thunderbolt in an external chassis) with a MADIface USB? They would be externally clocked from the same source of course. The aim is to get 128ch of MADI in at 96K. If you've tried it - how did it go?
