Hi Tom,
Can you give me a little more information about what midi you have assigned to the string track. For example, is it a style you've loaded in, is it Hi-Q, etc.
If you can be specific and let me know, I'll set it up and let you know what I did to get it playing. That will allow you to follow the steps and see if it works.
I don't have ST standalone so I can't try it out.
Also ...
1. Is ST loaded in the Stings slot of VST/DXi or the Default Synth slot?
(I take it that you are aware that the String Track in BIAB is assigned midi channel 6 and so the sound in ST would need to be assigned to midi channel 6.)
Regards,
Noel
