I can get samples for didgeridoos, shenais, shakuhatchis and other even more exotic instruments. What would be really nice would be to have a library of medieval and baroque instruments; recorders, shawms, krumhorns, mute cornets, rebecs, vielles, lutes, portative organs - that sort of things. A medieval ensemble makes a truly beautiful sound.
They have sound demos and some free samples to try.
Even if it's an old library, I find the samples very musical and true to the period.
I used some of the wind instruments in the false canon that happens from 1:06 on in this piece, if you want to hear how the samples sit with other libraries http://www.pablodelgado.com/mp3/scriptorium.mp3
