Music Studio query
 

I trying to convince a friend of mine to give linux a try. There are of course a few hurdles to overcome as always. The two main hurdles for my friend are gaming and his use of his pc as a music studio as he puts it. On the subject of gaming we could talk forever and get nowhere. What I want to know is what programs exist that will allow him to use linux as a music studio along with his creative prodikeys dm music keyboard?
