looks like Native Instruments Intakt
wich means, Timbaland is not using a intel mac
i thing the reason why he is using Intakt,
there are a millions of librarys, wich you can play in all rates, using the time machine modus.
you can do the same in Kontakt 3 on intel or for better timescratch quality use Digidesign Transfuser (only pro tools).
only problem with transfuser, there are not a millions of librarys yet
the SIDstation sounds like taken from here: YouTube - Producer Timbaland rips song from finnish musician?
he use the same sound for nelly furtado and 50cent/justin.
sampling 1 tone, using timemachine, playing the melody over, or a new one. YouTube - 50 Cent AYO Technology feat Justin Timberlake MUSIC VIDEO
