RE: Changing the buffer size in Asio driver mode
It's the nature of ASIO that it wants to talk to one application and one audio device at a time. The control panel for my MOTU interface flat refuses to run while any other audio application is open.
However, I can invoke the ASIO control panel from within SONAR because I have the "share drivers with other programs" option enabled. What this option does is tell SONAR to release the driver any time SONAR loses focus. That allows me to do things like bring up an external wave editor or the ASIO control panel or Windows Media Player while SONAR is loaded.
Go to Options -> Audio -> Advanced and check the "share drivers..." option.
All else is in doubt, so this is the truth I cling to. My Stuff
