Hi guys... just for the record, I was getting some latency with my toneport as well, (I was using it in sonar 4 with waves IR efficient)... but in the control panel settings of the asio drivers, (accessible through gearbox OR sonar) I reduced the buffers from 512 to 256 and it feels pretty much spot on now. I'm at work at the moment so I can't describe the method exactly, but you get the idea...
