I'd like to use the midi instruments in Logic's mainstage through Pd with the "keystation 61es" midi controller but would not know where to begin.

Any insight at all would be super neat.

Does anybody have any bright ideas how we might create a shepard tone in Pd?

I made a real basic one in protools but am doing my best to run in the opposite direction of said program. You can even just use a plugin, but seeing as that is boring, I'd appreciate any input.

Here's a link for a shepard tone refresher: http://en.wikipedia.org/wiki/Shepard_tone

Thanks. Yeah it was also used in the Dark Knight when Batman zips around on his uber bike. Sounds electric and always accelerating, kind of neat.
