I lost my favourite kits when my hard drive melted.
Had spent hours, layering and processing single hits taken from vinyl with sounds made on massive, ER-1 and my bass station.
I sold the ER-1 before the meltdown of my hard drive, so now I'm using what I have (Maschine software), layering as I go and trying to cop a few old, cheap drum machines I can sample to build up my library again.
I still have the vinyl I originally sampled but not had the time to really get digging into it again to find one shots - never wrote down what I used (I've got a pretty hap-hazard methodology)
