@azlsow3: I was responding to mudgel using a simplified conceptual model. I was trying to describe the software implementation, not the GUI.

Exactly the same way they display now. No change necessary.
Try it in Sonar. Make two clips, add some notes to each and overlap one clip with the other. (Semi-transparent clips would be nicer, even now)
I program midi solutions and am only too aware of the difficulties balancing usability with features. But the current clip implementation in Sonar is not satisfactory.
If you have the time, please try the following, you will understand the issue better than me describing with endless words. Imagine you have a song where the first 3 notes of the chorus are actually still inside the verse's bar, like "Blueberry Hill", if you know that song. To simulate this:
1) Create a midi track and press Alt+3 to open the PRV.
2) Place some notes in the first bar for the verse and at the end of the first bar add 3 notes going from low to high which are the "intro" to the chorus. Then add some notes in the second bar for the main part of the chorus.
Now imagine you want to rearrange the song so you now need to separate the verse and the chorus. Remember: the first 3 notes of the chorus are those at the end of the verse. How are you going to separate them into 2 clips?
So what I am proposing is the ability to make notes members of a clip, or remove membership from a clip. This by implementation necessitates notes without clip membership to be possible.
