Just double all the note values in the midi. that will make it half as fast 

I hate when my music comes out sounding half fast
 (say it out loud - lol).

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.

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

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?

Yeah, it works. Make sure groove clip looping is not enabled for the clip. Then select the midi clip then choose Process/Length from the top menu items and change the "By:_Percent" value to 200 and check both "Start Times" and "Durations". 


EDIT:
Unless something has changed since Sonar 7.


Try it yourself and let me know what you happens.

Incorrect, and WDI has twice explained that no copying and pasting is needed - you use Process/Length and ask for note start times and length to be doubled.  Obviously, this will make the clip play at half the speed as in the original clip, as Andypanda points out.

But the Length tool is a quick and easy way to change MIDI clips.  I use the process a lot, most often I use it for fast, tricky passages which I play at what is actually half the project tempo, then I shrink the clip by asking for start times and lengths to be reduced to 50% of the original.

I'm not sure if Triscuit really wants this MIDI track to play at half the time as the original, but he does say it's the wrong tempo and he need 80 measures to be 160 - if this is an accurate description of what he needs, this is the way to do it, and takes 2 seconds.

Yep. That was cleared three days ago.

Oh, OK -But there's no indication of it being "cleared" by Triscuit, the OP-- His last post asks the same question again.

This thread was helpful to people who weren't previously familiar with the great, simple "Length" tool - Very useful, and so much more straight-forward than Interpolate (which of course is super at other, more complicated edits).

Thank you very much to all that helped. Process/Length did just what I wanted. I knew there had to be a very easy solution, but I just couldn't put my finger on how to do it.

That's great, Triscuit - I appreciate that you came back to let us know your problem was solved.  It's good to add "Solved" in the subject line of a thread, then other people know they can find a tip on the thread.  This info about the Length tool was helpful to Kalle, and probably others who didn't know about it.  These kind of threads are so helpful, and even more so when the original poster edits the subject line to indicate the issue's been fixed.

Hello everyone.
Concerning stretching midi tracks. Yes it can be done. This is how I did it except I reduced the track length.
In Sonar X1 loaded a Roland midi file titled TXPLASMA. It is a mess as is. The Tempo is marked 250.00.
However the actual meter of the music is 140.00. The notes are all out of alignment/sync with the bars.
Changing the Tempo to 140.00 caused the music to play too slow. After reading at this forum I did some tests.
Set the Tempo at 140.00. Then highlight all tracks. Next click on Process and select Fit to Time and set New Thru 
from 92:03:032 to 56:03:032 and click Ok. The notes are now more closely aligned/synced with the bars. 
The music also fits the Tempo of 140.00. The notes can now be Quantized and tweaked to perfection. 
The Fit to Time process works in fractions being more versatile than the Length feature which works in percentages.
This is a good method for syncing Midi to Audio or Video. Hope this helps. 

Hi Guy's .New to sonar, but need to learn how to stretch  midis to make them longer for dancing,as I use them as backup,but some are so short as they were probably made with sheet music,which is usually somewhere between 2 & 3 minutes long. I need at least 5 minutes,but I don't know the process of stretching a midi . Is there a tutorial somewhere,or some one who can explain the process to me in language a 12 year old could understand. I'm a Guitar player ,not a midi maker,but i really need help please.  Thanks in advance   Larry  summerbreezelandn@yahoo.com

Welcome to the forum.
You can either
a. right-click the clip, select Edit>Copy then paste the clip after the original clip or
b. right-click the clip and select Groove Looping. The corners of the clip will become bevelled to show they are Groove Clips, then you can drag either end of the clip as far as you want and it will repeat.
