according to my pocket pc, there is a calypso carol, a caribbean band, and a caribbean. The caribbean will be available on the free technics download page in some weeks time if you are prepared to be patient.
In order of quality there are two caribes from the Ketron X1, a carib from the VA7, a carib from the Yamaha 9000 and a cariba from the KN800. I'm sure there must be others under other 'world' style names.
What sort of style is required?
