Yes, I know. I still have one in a box somewhere. There are ways to automate the device selection using batch files to swap out AUD.ini files before starting SONAR or autohotkey scripts to automate the preferences setting selections. That about exhausts all the possibilities I can think of.

Try to deselect the Delta drivers and select the Firewire one.  You may need to use a different driver model to get back to ASIO on the Firewire.

Well that's just the way it is unfortunately. It wasn't ever designed to be used in conjunction with other devices besides multiples of other 1010s. A total of 4 if I remember.

Why is it that you need to use the other device? Has it to do with inputs as the deltas don't have XLR connectors or some other reason.
