I've been controlling an XR-18 with an old laptop that runs XP. It handles the mixer just fine. Apparently, the built in sound card on the motherboard will not support ASIO drivers, so I can't use the USB bus to the laptop to record 16 channels to Tracktion. The Behringer ASIO drivers will not install to XP according to the error message. Any ideas how I can get around this without buying a new laptop? BTW, I love this mixer. Thanks for any constructive ideas.
