HD Native Thunderbolt and HD Native PCIe on Same System?
 

Pro Tools HD 2018.1 here on a 2013 Mac Pro running macOS 10.12.6.

I am switching my configuration over to a HD Native Thunderbolt and a Focusrite Red 4Pre. Both Port 1 and Port 2 on the 4Pre and the HD Native Thunderbolt are connected. This uses up the 64-channels on the HD Native Thunderbolt, of course.

Question: Can I add an HD Native PCIe in a Thunderbolt expansion chassis and add another max 64 I/O channels for a combined max 128 channels?

Note: I intend to put a couple of Focusrite RedNet 5 on the HD Native PCIe, if the above configuration works.

Any input is appreciated!

You cannot use multiple HD Native cards.
If you want more than 64 channels of IO then you have to go HDX.

Thanks for the input!

I assume the HD Native Thunderbolt cannot be used together with HDX cards?

You would assume correctly. :)
