I've gone too far to drop it now. It has roots all over the program. I don't know if I could remove it even if I wanted to.
Actually, I have to admit that the folks requesting music were right. Other competing programs have it, and it's one of the few additions that really might make a difference whether someone would purchase or not. I've only got a mock-up running, but have now become accustomed to hearing Pachelbel's soothing melody when the Aquarium starts up. I just wish I hadn't lost the nice orchestral MIDI file I had built. The temp version I downloaded isn't terrible, but would never be confused with a real orchestra.
