Humm.. Good topic.
I used to have my "pappers at school" done with video and multimedia, using my A500, then the A1200 and latter the A4000 and Scala. I'll try to grab a hold on them and tube-them so I can post here.
I also used my old 500 on top of my YamahaClavinova CPL550 Electric Piano so record my compositions via Midi. Those will be harder to find, but if I do, I'll tube them also.
