Hi Claude,

I've spent years trying to find a great sounding Acoustic bass library. I did buy Bandstand (which is not available anymore BTW) as well as many other libraries. None did the trick UNTIL I checked out Spectrasonics "Trilogy". WOW....talk about real. Now they have a new product which is an overhaul and update called "Trillium". I advise you to check out the videos for it. Acoustic, and Electric basses to die for with real slides, thumps, trills, slaps, etc. Amazing stuff!

Also a great contender is Vir 2 "Basis". Wonderful stuff here too!

Both worlds apart from Bandstand!
Hope this helps,
