Mobius - put your mind to it... [:)]
If you have both triple horn and Concert Toms, then they will almost certainly be much simpler than anything you already own as part of your VSL collection. Triple horn only has a couple of articulations, and the concert toms...well you just whack 'em - to coin a technical phrase given to me by a drummer.
If you need specifics, do post again, and I am sure that many forum users can point you in the right direction.
The concert toms came just at the right time for me, as I am working on a piece with real tribal sounding percussion, and these fit in beautifully!
