Hello you guys!
First of all I would like to say that I am new to this forum so please bear with me and my english (as it is not my native language).

Well, I like to produce new sounds based on instrument samples but I am having a lot of trouble finding just a few quality instrument samples. All the samples I can find on the web are either very low quality or filled with all kinds of effects. What I need are clean samples. Unfortunately I haven't got the money to buy sample CDs at the moment so I was looking for alternatives.

I have found this site which I recommend: http://theremin.music.uiowa.edu/MIS.html

But there HAS to be other sites like that one sharing a few nice and clean instrument recordings.
Therefore I thought that I would ask you guys. Do you know any good ressources for clean instrument (or choir) samples?

I am NOT looking for synthetic sounds and I am NOT looking for sounds with effects. Just a few clean instrument (or choir) samples in any reasonable format.

Thanks in advance!
