Hm...Sampletank is one of the ones that doesn't work here. I can get it to load sounds but it never plays them back in BIAB, or even in its own window (using its keyboard) in the selection window when I load it. It works fine in Reaper, though. I am using Windows 7, 64 bit. And I noticed that even after I load it once, it doesn't stay in the list of available soft synths.

I will try the suggestion about RealBand - I haven't used that at all yet.

Thanks for the suggestions.
