Combining Midi tracks to Sonar when using V700 console and Hilo Lynx...

So, I want to be able to add midi input from my Roland TD20 drums to the project simultaneously when using an outboard AD/DA.  The Lynx Hilo does not have MIDI. I have tried to figure this out but can't get it to work as long as the HILO drivers are loaded.
Any ideas? I use the V700 rack for midi input.
