Can't edit in MIDI

[JAMES P COSTELLO]

Hello all, 

For some reason, I can't edit my MIDI files.  When I double click on the "recorded" part, a piano roll does not appear.  Any ideas?

You can also have the Piano roll as part of the multi dock and if you have 2 monitors keep it open on the second screen. 

Just go to views on the main menu bar and choose Piano roll.
