I started just a tad later and fully digital than the gear in this article, so the floppy discs I got Scream Tracker on with its included samples plus whatever I could rip from a few .MODs I could get my hands on had to do. There were four tracks. There were a hundred samples, half of which was obscure crap (and even those found their use).
Building with it and making them sound awesome, plus discovering the amazing tricks the OGs of tracker & demo culture did with their editors (sliding and bending notes! dead stops in the middle of the sample!) was endless fun.
Nowadays, I get Native Instruments Ultimate — and despite sounding orders of magnitude better, all I do is toying around. I always have the nagging feeling there's gotta be one sound or effect in that endless library that's still better than the one I'm using right now.
