Connecting mpc studio together with waldorf blofeld and logi

Hey, i wonder if anyone knows the best and easiest way to have the logic 9, and then the mpc studio as a midi controller and the blofeld as a "modder" of the mpcs sounds, is this possible? plz heelp

what is a modder ? the studio only have midi in & out.
so you can connect your blofeld via usb midi from your blofeld into your computer. or you can connect your blofeld via midicable to your mpc studio.

then you have to connect the audio from your blofeld to your soundcard
