The guys of Wave Alchemy, have recently released a new free sample pack and here is a summary of what is said on their web site.
Tape KPR-77 by Wave Alchemy serves up over 280 free drum samples (recorded directly to 1/4″ analogue tape) from the Korg KPR-77 drum machine.
Tape KPR-77 contains three pre-mapped drum kit patches for use with Kontakt 2, 3, & 4 and Battery 3. Each kit makes use of extensive velocity layering, round robin sample playback and choke groups which in turn capture the quirkiness and expressiveness of the original unit.
