If you bought and registered it head over to NI's site and look for the Reaktor user library. Theres everything (well nearly) that you could want there.

Plus theres a load of ensembles (instruments) in the reaktor folder on your hard drive. (look in C..prog files..native instruments..reaktor 5..library..ensembles.... you should find 'classics' and 'new in R5' in there)

I love reaktor. Im not a builder but I find most things I want in the user library.

heres the link...
