Hi jonel, Here is how I did it, there may be an easier way because I do this in my DAW:
1-open two different versions of BiaB - setting in preference menu
2-BiaB1 is you main version. Have an utility track open, i.e. showing
3-BiaB2 is your trial version. Search for styles with MIDI drum tracks here
4-When you find one drag the drum track to the mid window in the drag and drop window and go into the drag and drop mode
5-drag the + window into BiaB1's utility track.
Note that I had to delete the BiaB2 to get BiaB1 to play and I had to mute the original drum track.
I did this on my Win 11 machine.

If you need help later today I can include pics.
I hope this helps

OK, a random thought;
Why does toilet paper need a commercial? Who's not buying it?

64 bit Win 10 Pro, the latest BiaB/RB, Roland Octa-Capture audio interface, a ton of software/hardware
