    What are you using for a "module" ?
    What external box is it? is it connected correctly? Is it a General Midi Device ?

    Yeah I can play any sound I want on the MPC from the Yamaha keyboard on Ch1. But on Ch2-16 I get the same Organ except for Ch10 I get the keyboards drum kit. I want to change the voice of the instrument on the Ch2,3 etc. I cant even figure out why Ch10 plays the drumkit and not the same organ as Ch2-9 and 11-16.

    The dude on the other messages board was correct in his response. You need to send a bank select / program change.

    You were further correct saying you needed to put this code in the MPC.

    What is the keyboard? Is it GM? If it is and you don't need anything other than the GM sounds, you can just send a program change.

    If you want to go beyond the "capital bank" (that is, the default bank one gets by simply sending a program change) you need to send a bank select.

    Typically, when sequencing it is good to have a blank bar (or two or how ever many you want) for "setup". In that setup bar, you can place preset mix info (patch changes, volume, panning, etc.)

    The bank select message will depend on the keyboard you're using. If the keyboard is GM, the bank select messages use controller 0 (MSB) and controller 32 (LSB). So, a program change with bank select message theoretically looks like this:

    1.1.000 controller 0, value x
    1.1.005 controller 32, value y
    1.1.010 program change, value z

    If you have a MIDI implementation chart, you can fill in the values of x, y and z to suit your needs.

    WOW! Everytime I think I'm gettin a grip on MIDI another door opens and I realize I how much I dont know.
    Thanks for the response. What you guys are saying about program changes makes sense now its just now I have to figure out how exactly to carry it out on the MPC.
    I'm gonna work on it some more. I'll probably get back to you.
    P.S what about this Midi charrt? is that a standard thing or is it something that is equipment specific?

    Oh so I find out now that GM reserves Ch10 for percussion that explains that mystery. Now to be able to change the others voices would be heavenly.
