Fsx Mcp

Hello folks out there im at the daunting task of now trying to connect up some more buttons on my sim, swicthes i have no problem with its with the encoders and the rotation sensors.
i have the 8/8/8 and the 0/16/16 boards and i have a usb encooder and a rotation sensor.
what im wanting to do is control the altitude control knob in the default 767 in FSX and perhaps navagation.

i have all of the software that is needed fuicp,etc etc. is it possible to be able to turn knob and see the altitude change in the FSX 767.

Thanks.......Robert
