Christmas 1976 my parents gave me an Arp Axxe, which was a simpler, less-expensive version of the much more famous Odyssey [1]. It was great for a kid to learn about electronic music because the controls were laid out to where you could visualize the signal flow. It also came with a great textbook. I learned a lot about sound and analog signal processing as well as had a lot of fun. May Mr. Pearlman rest in peace.
