I am a Ph. D. candidate in University of Illinois at Champaign-Urbana. My emphasis field is in computer-assisted music instruction. This summer, I designed two Hypercard programs to teach children to read music. Since these two programs include sound and animation, they took huge memory size. What I am trying to do right now is to find a way which allows me to incorporate multimedia into my program without occupying too much memory. If you haev any suggestion, please let me know. Thank you.
