The Ozone is almost an antique now, when M-Audio did the driver update for Win7-64 it was a package deal, so I cannot just install the driver. But in reality running it through the Saffire is faster than it was by itself. The minimum ASIO value for the Ozone was 128, and the Saffire decided it likes to be at 48, so is all good. 
 
Wow... just found out something else by dumb luck... the Saffire will drive X3 even when X3 is not the active program. I have never experienced that before... rather cool. I can play and be in the forum at the same time, lol.
