Eventhough MADIface USB can only use up to 64 channel audio (24bit/48KHz), is it possible that we can use both MADI input (optical and coaxial) at the same time by rerouting?

To be more specific, say, I have two MADI inputs, with one goes into MADI Coaxial and the other goes into MADI Optical. The signals are synchronized, using say coaxial in as clock. TotalMix can see all the 128 channels signals, but the recorder, i.e., Audacity can only record 64 channels.

Can I somehow "re-route" the signal in the MADI optical into the 64 channel?
