Drum Notation

Hi there,

I guess, this question must have been posted a lot of times, but unfortunately I didn't find an adequate answer...

• I open up a LogicPro Drum track
• I use presets to create some drum lines

• Now I want to manipulate/edit these automatically generated lines in the piano roll or the score editor
• The drum track is highlighted, I open the piano roll window
• And nothing is shown, just the remark: No midi region elected

Question is quite simple: How can I manipulate/edit an automatically generated drum line manually with the piano roll...?

Any ideas

Thanks a lot

Christian
