EMU not responding to MPCs channel pressure

Hi there,

alongside my MPC I use an EMU Sampler (E4XT Ultra with EOS 4.7) and yesterday I was trying to assign the MPCs aftertouch to the EMUs filterfrequency. I used the "press" cord but nothing happend. I set the channel pressure to "poly" so the pads send out data via midi which the EMU receives. Any Idea?

Solved it: The EMU responds to channel pressure messages, not poly pressure. So simply connecting an external midi controller to the MPC helped.
