Thanks for your replies.
To clarify some things.
- I use the latest BB version 2011.5
- I use the Garritan software which came with the Ewi usb.
Both programs work fine but if I open them together only the one I opened first will have “sound”.
The same thing occurs when I open two other programs that have sound, such as windows media player and the EWI (only the program that has started first will have sound.)
I checked Google but these questions are about how to use the ewi in BB. This is not what I’m looking for since I want to run the software separately. (Garritan for the EWI and BB for backing tracks)
Would buying an external sound card solve this problem?

Lots of thanks,
rodin
