Quote from Bill Etra:
"The dream was to create a compositional tool that would allow you to prepare visuals like a composer composes music. I called it then and I call it now “the visual piano”, because with the piano the composer can compose an entire symphony and be sure of what it will sound like. It was my belief then and it is my belief now after 40 years of working towards this, that this will bring about a great change and great upwelling of creative work once it is accomplished. This software is one step closer to that since, once we’re on the computer, things can be developed and repeated reliably."
