MADI at 96KHz works with no issues. I don’t understand why you want to limit to 16 channels though? Won’t the UFX+ do at least 32 channels at 96K? I’m able to run 24 channels to and from an SSL MADI Alphalink AX at 96KHz, but that’s only because it’s a 24 channel device. The H9000 will do 32 channels over MADI at 96KHz.
