Midi Notes ?

I was wondering can jj os 2 edit multiple midi notes at one time

in step edit?? no i dont think so

any mpc1000 os can edit multiple midi notes in one time with seq edit

Please do explain, I may tinker out some key's on my key board in different passes to get one solid take and find the last overdub is out of place by one or two ticks so then i go to the midi grid edit page to slide the notes and is like a million little dots to adjust. How do i go about grabbing what ever event i want and adjusting in one pass???
