Samplin is 1 of hip hop's foundations.
All them grooveboxes, samplers, samplin keyboards etc. had one thing in mind...., a feature which lets you record material from different sources & then offers functions to manipulate what you recorded.
Be it Korg, Ensonique, Yamaha, Roland, Akai, Boss, Emu etc and then of course the software samplers like Sampletank, Kontakt, Halion , Mach 5 etc...
Sampling has a direct correlation to Hip Hop music, It won't dissappear.
