mpc 2kxl w/reason

First let me tell you my set up first b4, I start. I am using my mpc 2000xl, with m audio ozonic, reason 3.0, recyle 2.1 with a mt4 emagic.
So I have a firewire pluse plus this emagic interface.
I want to do more with my mpc thou do i need another midi interface to be able to use it again
A bus= ozonic B bus= mt4

now the thing is I am saving some sequence on disk with the midi on reason, on the pc. So everytime i turn on the computer, I have to load up my mpc just to get that beat played i did b4.. now thats ok becuase I want it like that. but the thing is redrum have only 10 channels.
And by the way I can only use like 4 of the channel becuase for some reason my mpc is not playing all the channels. I need to know how to get all chennels to play together.
I want to be able to load up another sound module like mybe nntx and be able to save that on the disk to
becuase after thos 10 chennels are used I have to use the ozonic but I dont want to use the ozonic becuase it cant save on disk like the other stuff I have from the mt4
I only want to use that for basslines.

I am asking two different things hope you understand
