If there is, I've never heard of such a thing.
For years, bass players have tried to get close to the double bass sound......and not managed it. The fretless bass doesn't do it, the acoustic bass guitar doesn't do it although with flatwound strings and a bit of string buzzing it gets a bit closer than anything else. But that close is the kind of closeness that Canada has to Scotland as opposed to England....
Back in the 2004~2012 period when I'd sold my double bass because I'd heard these brilliant samples and thought that to be the answer {to a question I wasn't even asking at the time !}, I tried so many different VSTis and none of them did it. I tried out electric double basses and none of them really sounded like a double bass to me. Maybe I'd just tried the wrong ones.
In the end, come 2012, I just bought a cheap double bass again ! And I've not regretted it. It sounds like a double bass !? ??
