In my opinion, it's much easier and makes more sense musically to work solely in the PRV to do this type of work.
Reason? Well, I've noticed over the years that with certain soft synths, if you have note lengths which extend right up to the start of the next note Sonar will sometimes "miss" the new Note On message, so I'll drag the end of the first note back, not by much, maybe a few ticks but this guarantees that the first note will finish sounding and a new Note On message will be generated when the sequence reaches the new note.
This type of detailed editing is impossible in the Staff View, where a 1/4 is a 1/4 note and will always be a 1/4 note.
I have noticed this same thing myself when working in staff.... but it is easily remedied. It happens mostly when I am editing or manually inserting a new note. It never happens when I play the parts in on the keyboard. It will happen there only if I go to edit a wrong note or add a note. Then I must be aware of the overlap principle.
In staff, a quarter note doesn't (actually) have to be a quarter to sound like a quarter. well.... let me explain. If you set the note default resolution to quarters, you will get quarters (for manual input only), and if you have one quarter playing the same pitch followed by another exactly the same and they overlap by as much as one tick yes... the off/on signals will get lost. This happens when the snap to grid is turned off..... thus allowing the full quarter note to be placed on the staff exactly where you click, and not necessarily on the beat. It might be 10 ticks past the beat (2:02:010) but to the ear it sounds right, 10 ticks is hard to hear but midi never misses it......BUT... if that occurs, you simply right click to get to note properties and lower the duration number by a few ticks and waa laa, you have the notes sounding properly and when you reduce a note by a few ticks, your ear can not hear that difference.
If you prefer to edit in staff or PRV... it really doesn't matter... you can do it from either screen... it just depends on what YOU feel more comfortable working with. PRV may actually have some advantages in that you can draw in envelopes of velocity and a few other things more easily.
