Editing MIDI data

Hello,
I've been reading the manual, and from what I can tell, you cannot edit MIDI data in Notion unless you are working with a Sequencer staff. Is this correct? I'm trying to find out how to change MIDI controller data, including velocity and modulation wheel settings, to a staff that is not a Sequencer staff. Additionally, it would appear that you cannot enter notes in a step-by-step fashion in the Sequencer staff, only in real-time, which would suggest that based on my tinkering, you cannot change MIDI data for anything other than real-time recorded passages? This can't be right, so hopefully someone can point me to the right tool for seeing/editing this stuff on note staves.
Thanks.
