Hi Steve, You might want to Google for "sonar 6 producer 64 bit", and perhaps ask on the ddots list also. George.

I have Sonar 6 Producer installed on a win 7 64 bit pc. I'm using a Roland Edirole UA25X sound card. All seems to be working ok apart from some latency when recording. I am however using the windows driver and not the asio driver. When I go into the settings to change the driver to asio, I select asio from the list and then ok it but the settings window does not go away and the selection is not accepted. It just sits on the same window. I tried downloading the asio 4 all driver today and installing that but I still get the same result. Can anyone offer any suggestions. Steve
