I would probably prefer a MacPro rather than a laptop…..

Anyway, monitors connection is something you'll have to figure out in ProTools and setup the correct routing in the H8000FW, dedicating 2 analog outputs to that.

The H8000 has 8 inputs & outputs to DSPs. Depending on your configuration/PTools setup/H8000FW routing you may have less than that. The best way to get the most out of the H8000FW as a dedicated FX processor would be the use of a dedicated audio interface, possibly on a PCI bus of a desktop machine, and use the H8000FW on the FX busses.

On a laptop, frankly, things may get much more limited.

all the best
