Derb - assuming you can acquire the dexterity to finish medium drums, wait till you have to play just about the real drum tracks on hard and especially expert.
I don't see how a non-drummer could play some of the expert tracks without just practicing them forever.
And if/when they could play them, simply get them behind a kit, have them learn how to hit the drums & cymbals properly, and they're ready to play in front of a crowd.
Of course, it's hilarious and pretty interesting to see these guys on YouTube scoring perfects on expert drums, even, but their fills are completely unrhythmic POSs.
They can learn the parts, when the notes are given/required, but can they "feel" the music and play organically?
