Hi Nigel,
Probably is the wrong thing to be using with BIAB.
They are more like "riffs" which are mapped to individual keys (ie midi notes) on the keyboard.
So if you send notes to Kontakt via BIAB it will most likely chop & change the "riff" with every midi note it receives from BIAB. I don't have it (crossroad blues) but that's how it seems to work
Have a look at this video & watch the kontakt keyboard and see how a single note is triggered by a single note.
