I don't believe you can do it on the module. I can do it by putting the style in my E50, editing, and returning it to the Module. It's a bit of trouble though.

I think we would all like to change the actual bass lines on

the BK7 styles, it does not seem possible.

But we can however, change the bass instrument being used on

the style by using the Makeup Tools, this can be very useful.
