This may just be my opinion but I don't think a kaossilator will help with learning music theory, as it isn't an instrument as such. It is likely to help with rhythm though. 

If you do want to learn, get an electric instrument and use headphones. 

Silent, extremely portable instrument to learn music
i have downloaded some svg icons form the web which are all outlined paths. In illustrator i would like to make those paths thicker. Is there a way to do this? I know when a line is still in stroke-mode you can just adjust the size of the stroke, but once this has been converted to outlines i don't know if this is still possible?

thx
