I assume you mean WDM support, not DX/DXi. Anyway, since both SONAR and Project 5 have decent ASIO support, just use that:
I've used a Pulsar II (ASIO) with Project 5 v1 and it works fine. XTC mode on the other hand is a not entirely trivial to get working (but can be done).
I bought it for the instruments mainly. It works fine but has one crippling problem for me - it won't allow you to use more than one asio in at a time so if you have several ins (e.g. on my system I have inputs from VST instruments, Nord G2, Korg workstation and my Scope synths I'd like to be able to run side by side) it's a PITA.
