Hi Francis,

I am not very familiar with Digitech Trio, but if you want to capture it's sound to use in Band-in-a-Box, you can!

Take a look at this tutorial on creating UserTracks. You can use any kind of sound you want as a Band-in-a-Box RealTrack by making a UserTrack, meaning you can capture the exact tone of your Digitech Trio.

If you want to use a pre-existing RealTrack, you would need to go through the RealTracks you have and demo some of them to find one that sounds similar.

I hope that helps, I really recommend making UserTracks, it really opens up Band-in-a-Box to endless possibilities.

Cheers,
David
