Does anybody know of a sample library of steel-pan drums, like they use in Caribbean Calypso music?
This is a pitched melodic set of drums that function like a xylophone, if you are not familiar with them. Each drum has several tuned areas that produce a different pitch when struck with a mallet, and a number of drums are used to form an ensemble.
