Emu XL-7 & MP-7 User's Group

I loaded a 1-track-sequence from cubase to my mp-7. Everything worked 
well,  E-loadser transferred the file (around 5 k), I saw the midi in 
(mp-7) flashing, the new pattern arrived, track 1 was lit as its 
supposed to do, pattern length was 14 bars, all correct. But: No 
sound, when I´m playing it from my mp-7. I checked: No event or note 
in track 1 (despite its lit). I tried everything, different settings 
(midi rechannelise, saving pattern again and so on), it doesn´t work.

What Am I doing wrong?

Any ideas are very welcome.
