Are there any sample libraries or virtual instruments that you are particularly proud of owning or at least knowing about?
This could be a reference for musicians that are looking for more samples.
Has a lot of commercial collections of samples from classic synthesizers and sound-modules.
Interesting for people looking for a more vintage sound or just a lot of samples to play with.
A few freeware instrument VSTs. Includes an SF2 soundfont player VST.
A good all-purpose library. Much better quality than any GM soundfont you may find around the internet.
