Missing VST connection

Last week I rebuilt my system for a clean WIN10 machine. On re-loading CB7, it noticed that there were
two audio devices - a Creative sound card, and a Focusrite USB audio interface.
I selected the sound card. In the Devices/VST Conections/ only the sound card is shown. Is there a way
of selecting one of the on-line VST devices, or when chosen on first operation, does CB7 stick with that
device forever, or until re-loaded, when the initial choices are again displayed?

You can choose to set up whatever sound system you have available, but it can only do one at a time.

I’m not sure if people are having luck using ASIO 4 all for using parts of multiple systems together.
