>>>...I tried the Load Group function in the dxi window. No, that does not work. ...>>>

I have something similar that works, kind of. In Sample Tank I picked out my favorite bass, piano, drums, etc ... set to match up with BiaBs channel pref defaults. In Sampletank I saved this as a "Combi."

In practice I begin a song using Coyote. This gives the GM compatability BiaB requires, so I can hear what I an doing automatically.

My next-to-last step is to call up Sampletank, click on the word 'LOAD,' and then call up the "combi" I had saved earlier.

Then, I can go to sample tank again and change each instrument to another Sampletank selection, if needed.

(The last two steps are optional, and frequently skipped.)

Jazz Mammal has it right, and he explains it well. GM compatibility reflects a kind of old-school thinking. I tried setting up ST to be GM compatible and realized that my head was in the wrong place. Sampletank is just not meant to work that way.
