environments for logic 7

im trying to play instrauments in logic wiith mpc and keyboard. then just use mpc for sequencer and drum machine. Im having trouble creating an environment that splits the midi chanels effectively.does anyone know where to get good environments???

The enviornment would have to be a midi enviornment
in order for you to play the midi instruments not audio.

With my Logic Platinum 4 I can play three midi instruments
at one time and layer my track hope someone with Logic
seven can give you some better advice.

I know it has to do with pulling the midi trk up and creating
the scene from there somehow.
