I need to stretch a midi file in sonar. It's at the wrong tempo. This seems like something that should be easy to do. Why can't I figure this out? Someone help me out.

Just change the project tempo. MIDI will follow the project's tempo. Its audio that needs to be stretched.

That's what I thought too. There is something obvious I'm not seeing here. You see the project has audio clips so I can't change the tempo.

The midi clip is 80 measures. If I change the tempo it stays 80 measures long. I need it to stretch to 160 measures. This seems really easy. What am I missing?

Is there really no way to stretch a midi file from 80 measures to 160? I just need for someone to tell me it can't be done so I can start redoing the midi part.

Copy paste the MIDI track to a blank project, change the tempo, and bring it back.
I assume that should work.
Stretching is simply something that can not be fitted in the MIDi-formula.
 
Oops. I did not read your post #3 carefully enough. Changing the tempo has got nothing whatsoever to do with the number of measures.
That will remain the same no matter what you set the tempo to. Doubling the number of measures requires simply copy-pasting, AFAIK.

You didn't mention the audio tracks in the original post. That's a whole other ball of wax.

Depending on the nature of your audio track, this could be easy or it could be a lot of work.  You can use the process/fit-to-improv feature.  Look it up in the doc.  Basically, you need to create a click track that has a note-on MIDI event for each beat and those align with the beats in the audio track.  Sonar will then take care of remapping the MIDI accordingly.  The click track is a throwaway.  Once you've done the fit-to-improv, it's of no further use.

Process/Length should do it. Change to 200%.

Just double all the note values in the midi. that will make it half as fast and twice as long won't it? Is that what your trying to do? If that screwes up the measures go to meter/key and halve  the denominator. Anyway... something like that ought to fix it.

How would it do it for a MIDI track??? In midi a measure is a measure, no matter what the length or tempo is.
No Processing could change a 80-bar MIDI track into a 160-bar one, AFAIK (???) Or have you actually tested that it works?
