I suggested that way back with the first beta.
I will re post more here from your wishlist for other users:

Biab can generate up 7 tracks into RAM but you have 21 tracks in the Biab Plugin.
I suppose it could generate up the 7 style tracks into RAM but then if you want the extra tracks like multiriffs it would have to open another instance of BBW4/BB4 ?
As mentioned before, maybe the Biab Plugin could read the RAM that BBW4/BB4 writes directly, that way the BBW4/BB4 could be modified to write more tracks to another section of RAM using the same instance.

LOL But I think they have enough on their ToDoList at the moment to keep em going til 2030 smile
