well they're both white keys - look the same to me

....actually I think there are two types of arps - one is where you hit C 
with one finger and this whole arrangement plays in the key of C 
(including other notes) - the other kind, which I 'grew up on' on the 
Memory Moog, was where it only plays what your fingers are pressing. If 
you press CEG, you may get CEGCEGCEG... or decending GECGECGEC.... or 
CEGGECCEGGEC (up and down) or CGEGCGEGCGEGEGEGCGCGCCCGEEGC (random)., And 
if you let go of G, you get CECECECE or whatever. 

But again, I don't consider these 'ready to record' pieces of music. 
Maybe useful for getting some ideas.
