Sorry, I know, this is not the board to ask this, maybe you can still 
give me a hint:

Do you know how to change the midi-channel-setting of a track in 
cubase? I change it in the arrangement window, save it, when I reload 
it, it will appear under the previous midi channel I just changed. 
Checked the notes in the drumwindow though - clicking on a single 
note reveals the notes through the new midi-channel, the arrangement 
window says something different. When I load the pattern to my mp-7, 
it will appear under the previous unwanted channel. Hmm? Any 
suggestions? I checked the event-list , but where does the midi-
channelsetting hide? Or is it somewhere else?

Thanx for listening
