I have a file with many many changes in tempo ( it sounded good while listening) but when I get to singing with it I realize that the entire piece needs an increase in tempo but with all the variations intact..

Now, of the tempo was an envelope I'd just grab it and raise it up. But of course it isn't.
Is there any way in Sonar ( or with some external mfx) to accomplish this?

Thanks,
Fred

I would just go into your tempo map and increase each section by the same amount. I think its the only way to do it

CJ,  would the Process - Length    or   Process - Fit to time accomplish this?  I have never used either of these functions but from the description of what he is trying to do and what it says these functions do it seems like it may work.  I don't know if you can select the whole project or if there are any special considerations like ensuring all clips start at the same place or not.  Maybe someone can jump in here who has actually used these utilities.

You don't say, but I assume the existing tracks are all MIDI?  In any event, look up "Fit to time" or "Process-Fit to time" in the doc.  I think it may do exactly what you need.

I cant say for sure.. I never done what the poster is trying to do. I have changed the temp to a whole project with audio snap, but the project was the same tempo. Now, i have no clue if the poster means midi or audio.

What about a CAL script to do it?

Fred, you gave me an idea for a feature:
I wish the Tempo list was formatted like an excel spreadsheet. Then to bump everything up 20bpm or 20% it would be as simple as copying the list into excel, running the numbers through the right formula, and pasting it back in.

It would sure beat tweaking each entry of a drawn line manually. (But envelopes would be even nicer.)

Perhaps the Scale Tempo CAL script here?

I confess I've never tried fit-to-time, so I can't say with certainty it'll work.  But tempo control is a topic I'm pretty intently interested in and I've inferred from several other posts here over the last year that it'll do exactly what the OP wants.  Using a CAL script, as Reegs suggests, might work but it seems like it's using a bulldozer to drive a nail.  If fit-to-time keeps the relative tempo changes intact (and I'd bet money it will), it's just the hammer we need for the job.

Fit-to-time is the only solution.

A Tempo offset would be good to have eh?
