I use MLB4 free edition from burnill.co.uk which I've tweak over a year or
so but that one I just found above sounds very nice, not just louder than
MLB4. I like that the new software processors have MPX output on them. I'm
just downloading the broadcast ASIO version to try as I have ASIO drivers
for the terratec.
