For your standup bass and shofar needs...

Requires the latest version of Kontakt.
 
More may well be added as I find random stuff. Someone at VI wanted a Shofar (Ram's horn) and surprisingly freesound had it, so just wondering any requests? No guaranties of course, but I'll take a look and see what I can find / make.

Deeply sampled pan flute?

I can do a lightly sampled pan flute I think. Sadly there was a really nice free Kontakt panflute a couple years ago, but the link seems to have died...

To misquote "You can't always get what you want, but if you try sometimes bigcat make make a weird instrument."

PVC pipe and water make for funky sounding pan flutes of a sort maybe?
