I appreciate the detailed reply. We do have a decent Casio keyboard as we started her on piano lessons. However, she never practiced and doesn't seem like she really enjoyed it (I never saw her playing it by herself, even after we terminated the classes). That was more than 3 years ago so it is possible that we got her started prematurely.

Lately she has been listening to a lot of music and trying simplistic music mixing etc. I think I have realized to be more hands-off when it comes to her interests so I'm sort of just observing and hoping that it sticks. If that does happen, I think I'm not averse to the tools you mentioned.
