Thanks for all this info about sampletank. I don't have biab 2013 I have biab ultra pak 2012.

If I install sampletank free and buy the $10 expansion pack, do the adjustments in the second last post above, them I can set sampletank as the default dxi and it will play as a general midi dxi fine without further adjustment, that I won't need to pick an instrument for each biab track, though it may be possible to do that too?

Just want a fairly simple set up.

I take it realdrums will play along with it as well, without any tweaking?

Thanks for all the work and any further info.
