Sony Acid Music on PC. It cost about 50 pounds & I loved it. When I was a kid I had a few programs on my C64 like Electrosound & a couple of drum programs that were fun to play around with. Actually before I even had a PC I was using Codemasters Music on the Sony Playstation. That was fun but tedious to use. I missed out the whole tracker thing as I never had an Amiga/ST or PC in the early days.
