My son is open to all sorts of things. Show him an idea, and he'll think it's cool. Sometimes his interests last longer than others. As a father, I want to encourage him in a direction that he seems naturally inclined towards. Right now, he's showing a lot of interest in things like minecraft and watching youtube videos about things to do in minecraft. He also likes legos. And of course, his DS. I'm trying to find an entry point that isn't too expensive but gets him exposed to electronic creativity and music.
I'm starting to wonder if this might be a good entry point: http://www.amazon.com/Novation-Launchkey-Instrument-Controller-Keyboard/dp/B00F9SWH8G/ref=pd_ybh_3
