Some commercial products for latin/percussion stuff I happen to own:
- Latin Percussion EZX for EZ drummer. Not strictly loops, but comes with many usable MIDI grooves. They are maybe not as 100% realistic as recorded loops, but it is more versatile
- Some libraries for SampleTank: World Grooves
, Latin Brazil
, Latin Caribbean
, Latin Afro-Cuban
- zero-g Afrolatin Slam (http://www.zero-g.name/dlg/cart/inde...on=desc&pn=101
- Indie Adpak
for Addictive Drums comes with a rather nice Tambourine - simple, but convincing.
- Yellow Tool Independence comes with some good percussions, especially the Culture pack. But again, no loops here.
