Wow! My very first music-gaming PC was the Atari 1040ST running 'Notator' ! Awesome Rock Steady midi timing. It was subsequently replaced by Logic with groundbreaking GUI interface. It was a very sad day when Atari went out of business, but I guess they had no one to blame but themselves because they ignored their loyal musician following. I subsequently purchased a Mac & Logic on the Mac was fine, but nothing compared to on the midi rock steady Atari platform. I had to migrate to PC when I got into arrangers (for Yamaha & 3rd party utility software), so was happy to see Logic then available for PC, but with Apple taking it over, that went bye bye too. That said, Logic on the Mac remains (imho) the best Audio-Midi Sequencing Program available out there, and causing me to have a 2nd look at coming back to the Mac platform.
