Hi, Douglas !

I use Mixcraft 6 !
The way I have done is rendering the biab sgu file to wav
with the option to save each track separately.
After this I take each track into Mixcraft by using
the option open sound file (in Mixcraft) . After you have
copied each track to Mixcraft, you can do whatever you
like with them ! Hope this helped ?

Cheers
Dani
