I have a passion for the unusual and weird instruments from around the world.
I love what Tari and Bela D have done with Spiritual Winds.
But the Didgeridoo for instance is recorded only in one key. B.
I only know of one sample library that has the didgeridoo in every key and it does not have the playability of Spiritual Winds.
Other instruments that are rising in popularity at the moment is the Hang again as far as I know only one company has sampled this instrument so far...
So those are my choice..
