ifferent audio interfaces work differently with regard to opening or not when you click on the ASIO control panel from within Sonar. I happen to have a Presonus Audiobox 1818 VSL, and I make any changes in its UI from the system tray.
Exactly.
You have to change the ASIO buffer size for the VSL series from their control panel applet.
One nice thing about the VSL series is that the driver is very responsive (quick track arming and response to changes under preferences).
