One of the very first software packages for the early Macintosh, was Macromind's MusicWorks, released by Hayden Software in 1984. It was a nifty sequencer, although the sound from the Mac left something to be desired. However, I had a Yamaha DX11 synth and bought a midi connector for the Mac, so I could control the synth with the MusicWorks program, giving many more sonic options to play with.
In 1985, Hayden released Macromind's VideoWorks. VideoWorks was the first animation program for the Mac128K. It B&W, and 2D, but was still great fun to play with. It would eventually become Adobe Director. The years between the Mac launch in 1984 and 1986 were pretty lean in terms of software programs. However, I was pretty content with MacPaint, MusicWorks and VideoWorks, especially once I got my first scanner in 1985. My supervisor at the time, Dana, asked if I could whip up an animation for Brad Paxton, the head of the division. He wanted to suprise him on his birthday, when he turned on his Mac that day. Dana gave me a photo of Brad to scan and he wanted the top of Brad's head to lift up and show some circuit boards and stuff, with some sparks, saying "Happy Birthday" at the end.. It came out pretty well. Dana installed it on Brad's computer so it would run when he turned it on the next morning. Brad had a good laugh at it. And now Brad knew who I was.
