Drum 3P Midi Problems with Polyend Seq

[7even]

Hello Forum,

My problem is this: I connected the 3P to the Polyend Seq, but the Sequencer only sends Data to three channels in Global mode(two, three and six).

The only thing that differs in individual mode is that in Ch 1, Ch 4 or Ch 5 the 3P receives data in four channels
(2, 3, 6 + either 1, 4 or 5).

I think I choose all the options mentioned in the manual correctly:
Local - off, Channel - off, PC and CC - receive, Midi in/out connected to the Seq.

Both, the 3P and the Seq are new.

Which parameters do I have to change, to be able to play all six channels with the Seq at the same time?

Thanks in advance for your answers!

Update : problem solved. Channel selection error
on the Seq....
