How to automatically spread the PRV notation out?

I've written a project where, in the PRV notation, there are too many notes in one measure. I would like to spread them out by half a measure without affecting the project tempo (and without rewriting the track.) How do I do that?
 
Thanks!

Actually, this isn't one measure. I wrote about twenty measures of PRV notation at the wrong tempo. I want to maintain the tempo, but the measures tick by too slowly.
 
I'm only an amateur, so I guess the best way to explain it would be that I'm using the wrong "time signature"? The 4/4 is correct, but the measure count it too slow, so I wish to expand my work across a proper measure count.
 
How would I go about doing that?

The Fit Time function? I don't really understand the problem.

I think I did what he's talking about. I wrote a midi song and started with an arbitrary note length. And used that length to add new notes. It still lined up with the grid(by luck I think) but was not in time with the metronome. So I set the tempo I wanted and hand moved all the notes to their correct places. It took a while but I saw no other way to do it. First thing I do in a new song now is set the tempo and get the note lengths to what I want that match the grid.

EDIT: oops...ignore this post, I misunderstood the OP's issue
 
Maybe this will help?

EDIT: actually rather than make you read the whole thread...this is what I wrote in it (and Jeff Evans resolved)...if this is not the problem you're having then please disregard my suggestion-
More than a couple of times I've hastily started recording an idea (trying not to lose the idea) and somehow counted it (say a 4/4 metronome) as playing 1 and 2 and 3 and etc as opposed to 1,2,3,4 and had to start the whole thing over so that the instruments later added work out in the PRV and/or staff....so I really am hoping what Jeff is talking about would fix my goofs that will inevitably happen again. 

This is one of the most confusing threads I have seen in a long time.
 
I assume the OP must be talking about beats not notes in a measure, since there is no limit to the number of notes one can put in a measure depending on the duration of the notes, while the number of beats is fixed by the time signature. If so, then it would seem that he does not understand the basics of music notation. I am at a loss, however to figure out how he could cram say 6 quarter notes into a 4/4 measure in piano roll view. So I think we need a better explanation of the problem.
 
As far as midi playback is concerned, if the notes are at the correct time relationship to the tempo and to one another, then a tempo change will speed it up. But if individual notes are not at the proper duration, they need to be edited manually, since just speeding up the meter will not change the relative duration of the notes, just make each beat duration shorter or longer.

Maybe the length tool would work.  I'm not in front of my recording rig right now but it's under the "Process" heading (I think).  It has an option to adjust start times and duration.

I'm wondering if there is a CAL script that can do this.
