Perhaps you’ve already heard of Converse Rubber Tracks, this amazing library! Converse, in collaboration with http://www.Indabamusic.com have provided this incredible resource.
Sample types include full tracks (stems), loop files, and single hit “one-shots.”
Personally, I just downloaded Seth Haley’s samples of analogue synths (Juno, and a Modular). Thanks Seth, these are very cool!
Here is a link to the library, you should check it out:

You can easily collect and organize your favorite samples into a custom “Kit” (See the video, to see how).
