Midi setup

Hello everyone. I have been working with the MPC2500 and ran into some questions about the midi connection between the MPC and my Yamaha MM6.

I am looking to connect the MPC2500 with the Yamaha MM6 so that it would play the keyboard's internal sound.

I have tried several different combinations of the midi cable connections but the one that I have currently is: MM6 midi out ---> MPC midi in (A), MPC midi out (1) ----> MM6 midi in

In the MM6, I have turned off the local control and in the MPC2500, I have put the soft thru field to Omni A (I have also tried Omni-All and As Track).

I also have a Tascam US-144 for my audio interface. I have tried connecting the audio cables from the keyboard to the audio input of the US-144 and I have also tried connecting it to the audio in of the MPC. When I press the keyboard, the Tascam US-144's input L and R light up so I know that something is going through.

However, the result I get is the keyboard only playing the sounds loaded onto my MPC via the keys pressed. I do not get the internal sound of the MM6 at all.

Can anyone tell me what I can do to make this work? (or if getting the internal sounds of the MM6 is even possible through the MPC?)

Thank to everyone in advance.

Sorry if this is a daft question, but you have set the tracks midi channel on the main page to '1A' or something? and set synth recieve channel to '1'?
to stop the keyboard keys playing MPC sounds, just set the PGM field of the main page to 'off'
