I was just playing on my friends comp yesterday (new macbook pro) and loaded the kazoo patch, and he had logic open, and I hit the capslock key to engage the type>midi and hit a key on the keyboard and low and behold it played the comb in the kazoo patch! So to answer your question it will send midi on the same computer, and secondly you can use soundflower to pass the live audio to msp (once they make soundflower a UB)
