Extraordinary learning tool

I just discovered what an extraordinary learning tool Band In A Box can be. It's mostly used to generate music, of course; I'm generating the piano track for the silent comedy with it. But I can learn these catchy tunes myself this way: Band will print the sheet music. Morever, I can listen at a much slower tempo that does not distort the sound -- I can make it as slow as I want! With sheet music, audio, and an ability to slow it down without changing the pitch -- man, talk about a learning tool! Also, you can import midi files into Band and do the same. I didn't comprehend these features earlier, I was focused on generating music for video. But this may be the best learning tool I have. An exciting discovery.
