Susan Kare demonstrates the Macintosh in 1984, but it's vocoded. (Behringer VC340) 

Let's watch this adorable woman demonstrate the Apple Macintosh.. with the voice of angels!
This is an ode to the Behringer VC340.. arguably a "one trick pony". Actually it's a three-trick pony, since it's a fantastic string machine, it has a lovely vox humana, and of course it's a vocoder. The sound of a vocoder is like a seasoning.. you want to use it sparingly. In this video we unscrew the top of the salt shaker and dump out all the contents on top of your steak & lobster. Enjoy!
