Sorry that this question is very interface specific:
Does anyone know how to write a Max external that would control the internal routing of the FireFace? I know that the HDSP object written by Jhno does something very similar, but unfortunately it has not been updated to work in OS X or with the newer RME gear.
Being able to control the routing of the Fireface via MaxMSP would provide a near-zero latency controllable routing solution that would be amazing to use in live performance.
If anybody has suggestions, please help. I'm pretty desperate at this point. The TotalMix software that RME includes for this purpose is pretty useless for what I'm trying to do.
